Summary

Abstract:
The Canadian International Development Agency (CIDA) has sponsored analogue and digital aeromagnetic surveys in several countries. In certain cases the digital data are stored at the Geophysical Data Centre (GDC) while in other instances the host country holds these records. Datasets for each country were acquired during periods beginning in 1970 until 1991. As new data becomes available, it will be added to the database. Digital data is available at GDC for Cameroon, Ivory Coast, Pakistan, Rwanda, Upper Volta (Burkina Faso) (data from 1976-1980) and Zimbabwe. All countries, excluding Zimbabwe, require users to get permission from officials in that country in order to acquire the data from GDC. Data for Brazil, Guyana, Kenya, Mali, Niger, Thailand and Upper Volta (Burkina Faso) (data from 1972-1973) are not available in digital format or from GDC. Please contact CIDA for a representative in the country to get details on how to acquire the data.These data are being collected to assist in the understanding of the countries' landmass and near offshore regions. This knowledge is fundamental to mineral and hydrocarbon exploration, resource assessment, land utilization studies and identification of natural hazards.
