GIS & Geospatial Technologies: GIS Data

This guide provides GIS tutorials, data, books, course-specific GIS guides and other geospatial related information that might be of interest.

Browse Library geospatial data holdings: "The X drive" 

If you are a UC San Diego affiliate, you can browse the Library's geospatial data holdings that are located on what is known as the X Drive. The data is organized geographically, roughly by continent, with topical data arrangement inside each folder.

If you need a particular dataset, please request remote access to the Data & GIS Lab from your @ucsd email account. Pending approval, you will be granted remote access to the computers where you can access the data holdings. The Library geospatial data holdings can be browsed from this GitHub page of X drive data until we are able to publish the data into an online portal.

Remember, if you are looking for data on a smaller area of geography, be sure to check the folder with the larger geography first.  An example would be if you are looking for data for only one of the states in the United States, you would want to look in the United States Data folder as well as the North America data folder.
