Consortium for Spatial Information (CGIAR-CSI) is spatial science community that facilitates CGIAR’s international agricultural development research using spatial analysis, GIS, and remote sensing.
A very rich website with lots of GIS data from Columbia University portals such as CIESIN (Center for International Earth Science Information Network), SEDAC (Socioeconomic Data and Applications Center), and the World Data Center for Human Interactions.
An excellent site for GIS data for almost every country in the world. Very easy to use, comprehensive and a great starting point for files on administrative boundaries, water, roads, railroads, elevation, land cover, population, climate, and a gazetteer.
A product of the UN FAO, this site provides data on political boundaries, agriculture, climate, fisheries, forestry, water, land cover/use, population data, soil info and topo info.
From the Goddard Space Flight Center, this site offers access to portals for data on agriculture, atmosphere, biosphere, climate, human dimensions, oceans, earth, and more.
This gazetteer is a key resource to find the official name, latitude and longitude of domestic, foreign, Antarctic or undersea features. Note that if you are looking for foreign names, the link on the GNIS will take you to the GNS (also available as a link on this guide).
From OSU's Davey Jones' Locker, this is a great place to start any marine/coastal GIS project. Here you will find the full spectrum of links for agencies, bibliographies, conferences, data, labs, software tools and more.
