EBSCO Open Dissertations

EBSCO Open Dissertations makes electronic theses and dissertations (ETDs) more accessible to researchers worldwide. The free portal is designed to benefit universities and their students and make ETDs more discoverable. 

Increasing Discovery & Usage of ETD Research

EBSCO Open Dissertations is a collaboration between EBSCO and BiblioLabs to increase traffic and discoverability of ETD research. You can join the movement and add your theses and dissertations to the database, making them freely available to researchers everywhere while increasing traffic to your institutional repository. 

EBSCO Open Dissertations extends the work started in 2014, when EBSCO and the H.W. Wilson Foundation created American Doctoral Dissertations which contained indexing from the H.W. Wilson print publication, Doctoral Dissertations Accepted by American Universities, 1933-1955. In 2015, the H.W. Wilson Foundation agreed to support the expansion of the scope of the American Doctoral Dissertations database to include records for dissertations and theses from 1955 to the present.

How Does EBSCO Open Dissertations Work?

Your ETD metadata is harvested via OAI and integrated into EBSCO’s platform, where pointers send traffic to your IR.

EBSCO integrates this data into their current subscriber environments and makes the data available on the open web via opendissertations.org .

EBSCO Open Dissertations

Search millions of electronic theses and dissertations (etds).

With EBSCO Open Dissertations, institutions and students are offered an innovative approach to driving additional traffic to ETDs in institutional repositories. Our goal is to help make their students’ theses and dissertations as widely visible and cited as possible.

This approach extends the work started in 2014, when EBSCO and the H.W. Wilson Foundation created American Doctoral Dissertations which contained indexing from the H.W. Wilson print publication, Doctoral Dissertations Accepted by American Universities, 1933-1955. In 2015, the H.W. Wilson Foundation agreed to support the expansion of the scope of the American Doctoral Dissertations database to include records for dissertations and theses from 1955 to the present.

Get involved in the EBSCO Open Dissertations project and make your electronic theses and dissertations freely available to researchers everywhere. Please contact Margaret Richter for more information.

How to find resources by format

Why use a dissertation or a thesis.

A dissertation is the final large research paper, based on original research, for many disciplines to be able to complete a PhD degree. The thesis is the same idea but for a masters degree.

They are often considered scholarly sources since they are closely supervised by a committee, are directed at an academic audience, are extensively researched, follow research methodology, and are cited in other scholarly work. Often the research is newer or answering questions that are more recent, and can help push scholarship in new directions.

University of Minnesota Dissertations and Theses FAQs

What dissertations and theses are available.

With minor exceptions, all doctoral dissertations and all "Plan A" master's theses accepted by the University of Minnesota are available in the University Libraries system. In some cases (see below) only a non-circulating copy in University Archives exists, but for doctoral dissertations from 1940 to date, and for master's theses from 1925 to date, a circulating copy should almost always be available.

"Plan B" papers, accepted in the place of a thesis in many master's degree programs, are not received by the University Libraries and are generally not available. (The only real exceptions are a number of old library school Plan B papers on publishing history, which have been separately cataloged.) In a few cases individual departments may have maintained files of such papers.

In what libraries are U of M dissertations and theses located?

Circulating copies of doctoral dissertations:.

• Use Libraries Search to look for the author or title of the work desired to determine location and call number of a specific dissertation. Circulating copies of U of M doctoral dissertations can be in one of several locations in the library system, depending upon the date and the department for which the dissertation was done. The following are the general rules:
• Dissertations prior to 1940 Circulating copies of U of M dissertations prior to 1940 do not exist (with rare exceptions): for these, only the archival copy (see below) is available. Also, most dissertations prior to 1940 are not cataloged in MNCAT and can only be identified by the departmental listings described below.  
• Dissertations from 1940-1979 Circulating copies of U of M dissertations from 1940 to 1979 will in most cases be held within the Elmer L. Andersen Library, with three major classes of exceptions: dissertations accepted by biological, medical, and related departments are housed in the Health Science Library; science/engineering dissertations from 1970 to date will be located in the Science and Engineering Library (in Walter); and dissertations accepted by agricultural and related departments are available at the Magrath Library or one of the other libraries on the St. Paul campus (the Magrath Library maintains records of locations for such dissertations).  
• Dissertations from 1980-date Circulating copies of U of M dissertations from 1980 to date at present may be located either in Wilson Library (see below) or in storage; consult Libraries Search for location of specific items. Again, exceptions noted above apply here also; dissertations in their respective departments will instead be in Health Science Library or in one of the St. Paul campus libraries.

Circulating copies of master's theses:

• Theses prior to 1925 Circulating copies of U of M master's theses prior to 1925 do not exist (with rare exceptions); for these, only the archival copy (see below) is available.  
• Theses from 1925-1996 Circulating copies of U of M master's theses from 1925 to 1996 may be held in storage; consult Libraries search in specific instances. Once again, there are exceptions and theses in their respective departments will be housed in the Health Science Library or in one of the St. Paul campus libraries.  
• Theses from 1997-date Circulating copies of U of M master's theses from 1997 to date will be located in Wilson Library (see below), except for the same exceptions for Health Science  and St. Paul theses. There is also an exception to the exception: MHA (Masters in Health Administration) theses through 1998 are in the Health Science Library, but those from 1999 on are in Wilson Library.

Archival copies (non-circulating)

Archival (non-circulating) copies of virtually all U of M doctoral dissertations from 1888-1952, and of U of M master's theses from all years up to the present, are maintained by University Archives (located in the Elmer L. Andersen Library). These copies must be consulted on the premises, and it is highly recommended for the present that users make an appointment in advance to ensure that the desired works can be retrieved for them from storage. For dissertations accepted prior to 1940 and for master's theses accepted prior to 1925, University Archives is generally the only option (e.g., there usually will be no circulating copy). Archival copies of U of M doctoral dissertations from 1953 to the present are maintained by Bell and Howell Corporation (formerly University Microfilms Inc.), which produces print or filmed copies from our originals upon request. (There are a very few post-1952 U of M dissertations not available from Bell and Howell; these include such things as music manuscripts and works with color illustrations or extremely large pages that will not photocopy well; in these few cases, our archival copy is retained in University Archives.)

Where is a specific dissertation of thesis located?

To locate a specific dissertation or thesis it is necessary to have its call number. Use Libraries Search for the author or title of the item, just as you would for any other book. Depending on date of acceptance and cataloging, a typical call number for such materials should look something like one of the following:

Dissertations: Plan"A" Theses MnU-D or 378.7M66 MnU-M or 378.7M66 78-342 ODR7617 83-67 OL6156 Libraries Search will also tell the library location (MLAC, Health Science Library, Magrath or another St. Paul campus library, Science and Engineering, Business Reference, Wilson Annex or Wilson Library). Those doctoral dissertations still in Wilson Library (which in all cases should be 1980 or later and will have "MnU-D" numbers) are located in the central section of the third floor. Those master's theses in Wilson (which in all cases will be 1997 or later and will have "MnU-M" numbers) are also located in the central section of the third floor. Both dissertations and theses circulate and can be checked out, like any other books, at the Wilson Circulation desk on the first floor.

How can dissertations and theses accepted by a specific department be located?

Wilson Library contains a series of bound and loose-leaf notebooks, arranged by department and within each department by date, listing dissertations and theses. Information given for each entry includes name of author, title, and date (but not call number, which must be looked up individually). These notebooks are no longer current, but they do cover listings by department from the nineteenth century up to approximately 1992. Many pre-1940 U of M dissertations and pre-1925 U of M master's theses are not cataloged (and exist only as archival copies). Such dissertations can be identified only with these volumes. The books and notebooks are shelved in the general collection under these call numbers: Wilson Ref LD3337 .A5 and Wilson Ref quarto LD3337 .U9x. Major departments of individual degree candidates are also listed under their names in the GRADUATE SCHOOL COMMENCEMENT programs of the U of M, available in University Archives and (for recent years) also in Wilson stacks (LD3361 .U55x).

Obtaining Dissertations the Library Does Not Hold

Current University of Chicago faculty, students, and staff may borrow dissertations and theses by placing an interlibrary loan request .

Dissertations from U.S. or Canadian Institutions

ProQuest Dissertations and Theses contains records for most North American doctoral dissertations. To locate dissertations of interest, search by keyword.  Select More Search Options or use the Advanced search interface to search for terms in specific fields (Author, School, etc.).  Note that some fields (Abstract, Advisor, Committee Member, Department) will not work for dissertations produced before a certain date.  Most titles submitted since 1997 are available online.

The Theses Canada Portal provides additional information about Canadian theses.

Dissertations from Academic Institutions Outside the U.S.

Dissertations and theses from institutions outside the United States and Canada can sometimes be challenging to obtain. The Center for Research Libraries has a large collection of foreign dissertations. We borrow material from them, and in many cases interlibrary loan staff will ask CRL to acquire material they do not hold. See the CRL guide to dissertations for additional information.

Other Sources for Identifying Dissertations

While ProQuest Dissertations & Theses and the CRL Guide to Dissertations are good starting points, many of the Library's subscription databases contain records for dissertations. Along with the records for books and other material, WorldCat contains records for dissertations or theses held by member libraries. Most of the major subject-specific indexes (such as PsycINFO, SciFinder Scholar, or Sociological Abstracts) will also include citations for dissertations. Some of the Library's research guides mention additional sources.

The Library also has some print sources and bibliographies which you may use to locate dissertations. Locate these sources by searching the Library Catalog using the subject term Dissertations, Academic in either the subject keyword search or the Begins with subject search option. If you are looking for dissertations from a specific country, you can add the country into your search terms (i.e. Dissertations, Academic -- Mexico ).

CRL Dissertations

Based in Chicago, the Center for Research Libraries was founded in 1948 by a consortium of Midwestern universities seeking to pool lesser-used resources. The collection holds over 800,000 dissertations from 90+ universities in Germany (66%), Netherlands (2%), France (16%), Switzerland, Denmark, Norway, Sweden, and the UK; also from Latin America, South America, and Africa. What CRL does not own, it will acquire for interlibrary loan to Graduate Center affiliates.

British Dissertations

The Center for Research Libraries reviews all Grad Center ILL requests for loan or demand purchase of UK dissertations. If CRL finds the title accessible through EThOS or that it can be digitized free of charge (in approx 30 days), CRL will notify the requesting institution of its availability via the EThOS online venue. CRL will also place orders via EThOS and alert requestors when a dissertation is available for download. If EThOS requires a fee for digitization, CRL will place the order on behalf of the requesting institution and pay for digitization.

Search Help

Get the most out of Google Scholar with some helpful tips on searches, email alerts, citation export, and more.

Finding recent papers

Your search results are normally sorted by relevance, not by date. To find newer articles, try the following options in the left sidebar:

• click "Since Year" to show only recently published papers, sorted by relevance;
• click "Sort by date" to show just the new additions, sorted by date;
• click the envelope icon to have new results periodically delivered by email.

Locating the full text of an article

Abstracts are freely available for most of the articles. Alas, reading the entire article may require a subscription. Here're a few things to try:

• click a library link, e.g., "FindIt@Harvard", to the right of the search result;
• click a link labeled [PDF] to the right of the search result;
• click "All versions" under the search result and check out the alternative sources;
• click "Related articles" or "Cited by" under the search result to explore similar articles.

If you're affiliated with a university, but don't see links such as "FindIt@Harvard", please check with your local library about the best way to access their online subscriptions. You may need to do search from a computer on campus, or to configure your browser to use a library proxy.

Getting better answers

If you're new to the subject, it may be helpful to pick up the terminology from secondary sources. E.g., a Wikipedia article for "overweight" might suggest a Scholar search for "pediatric hyperalimentation".

If the search results are too specific for your needs, check out what they're citing in their "References" sections. Referenced works are often more general in nature.

Similarly, if the search results are too basic for you, click "Cited by" to see newer papers that referenced them. These newer papers will often be more specific.

Explore! There's rarely a single answer to a research question. Click "Related articles" or "Cited by" to see closely related work, or search for author's name and see what else they have written.

Searching Google Scholar

Use the "author:" operator, e.g., author:"d knuth" or author:"donald e knuth".

Put the paper's title in quotations: "A History of the China Sea".

You'll often get better results if you search only recent articles, but still sort them by relevance, not by date. E.g., click "Since 2018" in the left sidebar of the search results page.

To see the absolutely newest articles first, click "Sort by date" in the sidebar. If you use this feature a lot, you may also find it useful to setup email alerts to have new results automatically sent to you.

Note: On smaller screens that don't show the sidebar, these options are available in the dropdown menu labelled "Year" right below the search button.

Select the "Case law" option on the homepage or in the side drawer on the search results page.

It finds documents similar to the given search result.

It's in the side drawer. The advanced search window lets you search in the author, title, and publication fields, as well as limit your search results by date.

Select the "Case law" option and do a keyword search over all jurisdictions. Then, click the "Select courts" link in the left sidebar on the search results page.

Tip: To quickly search a frequently used selection of courts, bookmark a search results page with the desired selection.

Access to articles

For each Scholar search result, we try to find a version of the article that you can read. These access links are labelled [PDF] or [HTML] and appear to the right of the search result. For example:

A paper that you need to read

Access links cover a wide variety of ways in which articles may be available to you - articles that your library subscribes to, open access articles, free-to-read articles from publishers, preprints, articles in repositories, etc.

When you are on a campus network, access links automatically include your library subscriptions and direct you to subscribed versions of articles. On-campus access links cover subscriptions from primary publishers as well as aggregators.

Off-campus access

Off-campus access links let you take your library subscriptions with you when you are at home or traveling. You can read subscribed articles when you are off-campus just as easily as when you are on-campus. Off-campus access links work by recording your subscriptions when you visit Scholar while on-campus, and looking up the recorded subscriptions later when you are off-campus.

We use the recorded subscriptions to provide you with the same subscribed access links as you see on campus. We also indicate your subscription access to participating publishers so that they can allow you to read the full-text of these articles without logging in or using a proxy. The recorded subscription information expires after 30 days and is automatically deleted.

In addition to Google Scholar search results, off-campus access links can also appear on articles from publishers participating in the off-campus subscription access program. Look for links labeled [PDF] or [HTML] on the right hand side of article pages.

Anne Author , John Doe , Jane Smith , Someone Else

In this fascinating paper, we investigate various topics that would be of interest to you. We also describe new methods relevant to your project, and attempt to address several questions which you would also like to know the answer to. Lastly, we analyze …

You can disable off-campus access links on the Scholar settings page . Disabling off-campus access links will turn off recording of your library subscriptions. It will also turn off indicating subscription access to participating publishers. Once off-campus access links are disabled, you may need to identify and configure an alternate mechanism (e.g., an institutional proxy or VPN) to access your library subscriptions while off-campus.

Email Alerts

Do a search for the topic of interest, e.g., "M Theory"; click the envelope icon in the sidebar of the search results page; enter your email address, and click "Create alert". We'll then periodically email you newly published papers that match your search criteria.

No, you can enter any email address of your choice. If the email address isn't a Google account or doesn't match your Google account, then we'll email you a verification link, which you'll need to click to start receiving alerts.

This works best if you create a public profile , which is free and quick to do. Once you get to the homepage with your photo, click "Follow" next to your name, select "New citations to my articles", and click "Done". We will then email you when we find new articles that cite yours.

Search for the title of your paper, e.g., "Anti de Sitter space and holography"; click on the "Cited by" link at the bottom of the search result; and then click on the envelope icon in the left sidebar of the search results page.

First, do a search for your colleague's name, and see if they have a Scholar profile. If they do, click on it, click the "Follow" button next to their name, select "New articles by this author", and click "Done".

If they don't have a profile, do a search by author, e.g., [author:s-hawking], and click on the mighty envelope in the left sidebar of the search results page. If you find that several different people share the same name, you may need to add co-author names or topical keywords to limit results to the author you wish to follow.

We send the alerts right after we add new papers to Google Scholar. This usually happens several times a week, except that our search robots meticulously observe holidays.

There's a link to cancel the alert at the bottom of every notification email.

If you created alerts using a Google account, you can manage them all here . If you're not using a Google account, you'll need to unsubscribe from the individual alerts and subscribe to the new ones.

Google Scholar library

Google Scholar library is your personal collection of articles. You can save articles right off the search page, organize them by adding labels, and use the power of Scholar search to quickly find just the one you want - at any time and from anywhere. You decide what goes into your library, and we’ll keep the links up to date.

You get all the goodies that come with Scholar search results - links to PDF and to your university's subscriptions, formatted citations, citing articles, and more!

Library help

Find the article you want to add in Google Scholar and click the “Save” button under the search result.

Click “My library” at the top of the page or in the side drawer to view all articles in your library. To search the full text of these articles, enter your query as usual in the search box.

Find the article you want to remove, and then click the “Delete” button under it.

• To add a label to an article, find the article in your library, click the “Label” button under it, select the label you want to apply, and click “Done”.
• To view all the articles with a specific label, click the label name in the left sidebar of your library page.
• To remove a label from an article, click the “Label” button under it, deselect the label you want to remove, and click “Done”.
• To add, edit, or delete labels, click “Manage labels” in the left column of your library page.

Only you can see the articles in your library. If you create a Scholar profile and make it public, then the articles in your public profile (and only those articles) will be visible to everyone.

Your profile contains all the articles you have written yourself. It’s a way to present your work to others, as well as to keep track of citations to it. Your library is a way to organize the articles that you’d like to read or cite, not necessarily the ones you’ve written.

Citation Export

Click the "Cite" button under the search result and then select your bibliography manager at the bottom of the popup. We currently support BibTeX, EndNote, RefMan, and RefWorks.

Err, no, please respect our robots.txt when you access Google Scholar using automated software. As the wearers of crawler's shoes and webmaster's hat, we cannot recommend adherence to web standards highly enough.

Sorry, we're unable to provide bulk access. You'll need to make an arrangement directly with the source of the data you're interested in. Keep in mind that a lot of the records in Google Scholar come from commercial subscription services.

Sorry, we can only show up to 1,000 results for any particular search query. Try a different query to get more results.

Content Coverage

Google Scholar includes journal and conference papers, theses and dissertations, academic books, pre-prints, abstracts, technical reports and other scholarly literature from all broad areas of research. You'll find works from a wide variety of academic publishers, professional societies and university repositories, as well as scholarly articles available anywhere across the web. Google Scholar also includes court opinions and patents.

We index research articles and abstracts from most major academic publishers and repositories worldwide, including both free and subscription sources. To check current coverage of a specific source in Google Scholar, search for a sample of their article titles in quotes.

While we try to be comprehensive, it isn't possible to guarantee uninterrupted coverage of any particular source. We index articles from sources all over the web and link to these websites in our search results. If one of these websites becomes unavailable to our search robots or to a large number of web users, we have to remove it from Google Scholar until it becomes available again.

Our meticulous search robots generally try to index every paper from every website they visit, including most major sources and also many lesser known ones.

That said, Google Scholar is primarily a search of academic papers. Shorter articles, such as book reviews, news sections, editorials, announcements and letters, may or may not be included. Untitled documents and documents without authors are usually not included. Website URLs that aren't available to our search robots or to the majority of web users are, obviously, not included either. Nor do we include websites that require you to sign up for an account, install a browser plugin, watch four colorful ads, and turn around three times and say coo-coo before you can read the listing of titles scanned at 10 DPI... You get the idea, we cover academic papers from sensible websites.

That's usually because we index many of these papers from other websites, such as the websites of their primary publishers. The "site:" operator currently only searches the primary version of each paper.

It could also be that the papers are located on examplejournals.gov, not on example.gov. Please make sure you're searching for the "right" website.

That said, the best way to check coverage of a specific source is to search for a sample of their papers using the title of the paper.

Ahem, we index papers, not journals. You should also ask about our coverage of universities, research groups, proteins, seminal breakthroughs, and other dimensions that are of interest to users. All such questions are best answered by searching for a statistical sample of papers that has the property of interest - journal, author, protein, etc. Many coverage comparisons are available if you search for [allintitle:"google scholar"], but some of them are more statistically valid than others.

Currently, Google Scholar allows you to search and read published opinions of US state appellate and supreme court cases since 1950, US federal district, appellate, tax and bankruptcy courts since 1923 and US Supreme Court cases since 1791. In addition, it includes citations for cases cited by indexed opinions or journal articles which allows you to find influential cases (usually older or international) which are not yet online or publicly available.

Legal opinions in Google Scholar are provided for informational purposes only and should not be relied on as a substitute for legal advice from a licensed lawyer. Google does not warrant that the information is complete or accurate.

We normally add new papers several times a week. However, updates to existing records take 6-9 months to a year or longer, because in order to update our records, we need to first recrawl them from the source website. For many larger websites, the speed at which we can update their records is limited by the crawl rate that they allow.

Inclusion and Corrections

We apologize, and we assure you the error was unintentional. Automated extraction of information from articles in diverse fields can be tricky, so an error sometimes sneaks through.

Please write to the owner of the website where the erroneous search result is coming from, and encourage them to provide correct bibliographic data to us, as described in the technical guidelines . Once the data is corrected on their website, it usually takes 6-9 months to a year or longer for it to be updated in Google Scholar. We appreciate your help and your patience.

If you can't find your papers when you search for them by title and by author, please refer your publisher to our technical guidelines .

You can also deposit your papers into your institutional repository or put their PDF versions on your personal website, but please follow your publisher's requirements when you do so. See our technical guidelines for more details on the inclusion process.

We normally add new papers several times a week; however, it might take us some time to crawl larger websites, and corrections to already included papers can take 6-9 months to a year or longer.

Google Scholar generally reflects the state of the web as it is currently visible to our search robots and to the majority of users. When you're searching for relevant papers to read, you wouldn't want it any other way!

If your citation counts have gone down, chances are that either your paper or papers that cite it have either disappeared from the web entirely, or have become unavailable to our search robots, or, perhaps, have been reformatted in a way that made it difficult for our automated software to identify their bibliographic data and references. If you wish to correct this, you'll need to identify the specific documents with indexing problems and ask your publisher to fix them. Please refer to the technical guidelines .

Please do let us know . Please include the URL for the opinion, the corrected information and a source where we can verify the correction.

We're only able to make corrections to court opinions that are hosted on our own website. For corrections to academic papers, books, dissertations and other third-party material, click on the search result in question and contact the owner of the website where the document came from. For corrections to books from Google Book Search, click on the book's title and locate the link to provide feedback at the bottom of the book's page.

General Questions

These are articles which other scholarly articles have referred to, but which we haven't found online. To exclude them from your search results, uncheck the "include citations" box on the left sidebar.

First, click on links labeled [PDF] or [HTML] to the right of the search result's title. Also, check out the "All versions" link at the bottom of the search result.

Second, if you're affiliated with a university, using a computer on campus will often let you access your library's online subscriptions. Look for links labeled with your library's name to the right of the search result's title. Also, see if there's a link to the full text on the publisher's page with the abstract.

Keep in mind that final published versions are often only available to subscribers, and that some articles are not available online at all. Good luck!

Technically, your web browser remembers your settings in a "cookie" on your computer's disk, and sends this cookie to our website along with every search. Check that your browser isn't configured to discard our cookies. Also, check if disabling various proxies or overly helpful privacy settings does the trick. Either way, your settings are stored on your computer, not on our servers, so a long hard look at your browser's preferences or internet options should help cure the machine's forgetfulness.

Not even close. That phrase is our acknowledgement that much of scholarly research involves building on what others have already discovered. It's taken from Sir Isaac Newton's famous quote, "If I have seen further, it is by standing on the shoulders of giants."

The theoretical mechanism of the sublimation of uranium hexafluoride are considered. The most contribution to the rate of evaporation of UF 6 is introduced by the conductive mode of heat exchange. Various modes of the intensification of the evaporation of uranium hexafluoride during the nitrogen supply in pulse mode to the product mass are investigated. The nitrogen supply results in the turbulization of gas flow within a vessel (Re = 2500–4000) and significantly increases the rate of evaporation of uranium hexafluoride with the substantial decrease in a weight of the nonevaporable residue of 5.6–1.0 kg. The complex application of the pulse nitrogen supply in combination with heating the bottom of the vessel is the most effective method for evaporating uranium hexafluoride. The rate of evaporation of UF6 increases by a factor of almost four in comparison with the design mode. The developed methods are applied in industry and provide the stable operation of Saturn reactors during the conversion of uranium hexafluoride into its dioxide.

WGS 84 coordinate reference system is the latest revision of the World Geodetic System, which is used in mapping and navigation, including GPS satellite navigation system (the Global Positioning System).

Geographic coordinates (latitude and longitude) define a position on the Earth’s surface. Coordinates are angular units. The canonical form of latitude and longitude representation uses degrees (°), minutes (′), and seconds (″). GPS systems widely use coordinates in degrees and decimal minutes, or in decimal degrees.

Latitude varies from −90° to 90°. The latitude of the Equator is 0°; the latitude of the South Pole is −90°; the latitude of the North Pole is 90°. Positive latitude values correspond to the geographic locations north of the Equator (abbrev. N). Negative latitude values correspond to the geographic locations south of the Equator (abbrev. S).

Longitude is counted from the prime meridian ( IERS Reference Meridian for WGS 84) and varies from −180° to 180°. Positive longitude values correspond to the geographic locations east of the prime meridian (abbrev. E). Negative longitude values correspond to the geographic locations west of the prime meridian (abbrev. W).

UTM or Universal Transverse Mercator coordinate system divides the Earth’s surface into 60 longitudinal zones. The coordinates of a location within each zone are defined as a planar coordinate pair related to the intersection of the equator and the zone’s central meridian, and measured in meters.

Elevation above sea level is a measure of a geographic location’s height. We are using the global digital elevation model GTOPO30 .
