African Marine Atlas
What is AMA?
The purpose of the African Marine Atlas (AMA) is to identify, collect and organize available geospatial datasets into an atlas of environmental themes for Africa, under the sponsorship of the ODINAFRICA Project of the Intergovernmental Oceanographic Commission's (IOC) International Oceanographic Data and Information Exchange (IODE) Programme. The African Marine Atlas will include and involve a number of other geo-spatial data projects on and around the African continent.
At the present time, the majority of the data layers in the African Marine Atlas are
continental-scale, but the structure of this interface already allows for the
inclusions of national- and local-scale layers. All the African Marine Atlas datasets, images and
grids use the standard GIS mapping convention of signed decimal degrees, with
longitudes ranging from -180 to +180 (i.e. not 0 to 360). No data are
projected, and as far as can be determined all data products are provided in "geographic coordinates" using the
WGS84 Datum, in absence of
other information. Seasonal references in the datasets refer to the
northern (boreal) seasons (i.e. winter ranges from January to March),
unless otherwise stated.
How to use the African Marine Atlas data?
The African Marine Atlas is comprised of easily downloadable data on
various key themes relevant to the marine and coastal environment of
Africa. The download data sets can be used in many
geographical information systems, including the most common commercial and
public domain systems. AMA also contains dataset descriptions and
links to the original publisher and/or current source of the data, and
links to pertinent metadata records, when available. This atlas is
intended both to provide necessary datasets directly to concerned
scientists, and to set the stage for the development of decision-makers' toolkits that rely on geospatial
