ABSTRACT
A New Landcover Map of Central Africa derived from Multiresolution, Multitemporal Satellite Observations

We describe a new map of the Central African region that was derived from NOAA AVHRR observations using a fusion of Local (LAC, 1 km), Global Area Coverage (GAC, 8 km), and ancillary information. The land cover map, produced for the Central Africa Regional Program for the Environment ( CARPE), offers a synoptic view of the extent of central Africa dense humid forests, at relatively fine spatial resolution. Land cover types include dense humid forest, disturbed or degraded forest and various savanna classes. Ancillary information includes political and park boundaries, settlements, rivers and roads. Map validation was performed using a combination of field visits and finer resolution imagery (Landsat MSS). Forest cover type mapping errors were at most 20%. The resulting map is useful for addressing a number of resource management issues, a few of which are examined.
