ESA Gabon Station Oil Spill Detection
The ground "footprint" for the ERD-series and
other synthetic aperture satellites in Gabon facilitates tracking oil spills
and other shipping pollution. The best coverage includes the Gulf of Guinea
and western coast of central Africa, including the Cabinda enclave of Angola.
Waters off the coast of Cameroon can be observed regardless of weather.

Space Agency SAR data for Central Africa
ESA-ESRIN reported in 1996 it had completed and
in some instances had ongoing projects testing Synthetic Aperture Radar
in Central Africa. Projects included map updating, pipeline planning, volcano
monitoring, water pollution and ship detection and others. Imagery and
other data is available for Cameroon, Central African Republic, Congo (Brazzaville),
Equatorial Guinea, Gabon, Guinea-Bissau, Nigeria and parts of former Zaire.
Famine
Early Warning System - FEWS
This sophisticated U.S. AID-funded project merges
weather imagery, rainfall data, ground observation, local price information
for agricultural products and related data for the entire continent of
Africa. Its objective is to provide early warning of potential food and
water crises. Much weather satellite imagery is available online.
