USGS maintains its core strengths in characterizing and understanding complex Earth and biological systems through research; modeling; highly accurate topographic, geologic, hydrographic, and biogeographic maps; and delivery of high-quality earth observation data. Programs include cooperative data collection systems, cross-boundary synthesis, and scientific data delivery for users worldwide. USGS...

The purpose of the Program is to develop a sound understanding of the potential for development of potable groundwater supply in selected African countries and build local capacity to plan and conduct the hydrologic investigations and monitoring necessary to help ensure that groundwater resources are developed and managed efficiently and sustainably.

The US Geological Survey collaborated with Northern Arizona University and New Mexico State University in a project funded by the United States Agency for International Development-Kenya and East Africa Mission to investigate the use of satellite image data, along with hydrological and geological data sets, to research and develop maps of the potential of groundwater resources in southern Turkana...

Landscapes of West Africa: A Window on a Changing World is an atlas and unique dataset that uses time-series satellite image data and field-based photography to tell the story of wide-ranging land change across 17 countries. EROS scientists selected the years 1975, 2000 and 2013 to characterize the landscapes and create the product, which represents the broadest effort to map the region in history...
