Browse Library geospatial data holdings: "The X drive" 

UC San Diego affiliate can browse the Library's geospatial data holdings that are hosted on the X drive in our Data & GIS Lab. You must be connected to UCSD VPN in order to browse. This is for BROWSING ONLY. You CANNOT DOWNLOAD any files. You must visit the Lab to access files until we are able to publish the data into an online portal (currently under development)

The data is organized geographically, roughly by continent, with topical data arrangement inside each folder.

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.
