African Magnetic Mapping Project (AMMP)

Participants

Paterson, Grant & Watson Limited (PGW), in collaboration with GETECH and ITC, compiled all the available airborne and marine magnetic surveys for the continent of Africa.

Data

• The known surveys number approximately 800 individual datasets, acquired largely for hydrocarbon and mineral exploration interest.
• Coverage is approximately 80% of the land and continental shelf area.
• Survey data from 1948 to 1992 and cover all 52 African nations.

Products

• Survey Atlas - location and specifications for all surveys.
• Digital Technical Database - all original survey specifications and processing parameters.
• Map Atlases - 1:2,000,000 and 1:5,000,000 shaded relief total field magnetic maps.
• Country Digital Grids - 1 km x 1 km grid draped on topography.
• Higher resolution magnetic and radiometric data is available for selected surveys (with the permission of the original owner).
