GeoSEER - The Spatial Data Search Engine
There are many thousands of public-facing web-services out there using the OGC (new window) standards (WMS, WFS, WCS, WMTS) to serve data, but they have only limited discoverability. We wanted to create a search engine that would bring all of these services into a single place, so we created GeoSeer.

Global Administrative Areas (GADM)
GADM provides maps and spatial data for all countries and their sub-divisions. You can browse our maps or download the data to make your own maps.

Marine Ecoregions of the World
Marine Ecoregions of the World (MEOW) is a biogeographic classification of the world's coasts and shelves. It is the first ever comprehensive marine classification system with clearly defined boundaries and definitions and was developed to closely link to existing regional systems. The ecoregions nest within the broader biogeographic tiers of Realms and Provinces.|

Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales.

 

North American River Width Dataset
NARWidth is composed of planform morphometric measurements of North American rivers at approximately mean discharge. It was created using image processing algorithms on Landsat TM and ETM+ imagery. NARWidth is intended to be used in a wide variety of scientific and engineering applications including hydrologic, hydraulic, and biogeochemical models. Additional information can be found in the Data Set Development page and in this GRL article (pdf).
