A national topographic manping program is equired for the prober utilisation of natural resources in developing countries In many of these countries mans are often comniled piecemeal and at various scales This resulte in patchy coverage of the total land area at great expense. It also delays the evaluation of unexolored regicns Recent advances in photo acouisttion and cartographic technology allow the rapld implementation cf a technolomlcally proftclent data collection and analysis system for netionel mapping and rescurce surveys. The desertbed systen ineludes examples cf hardware componente and operattonal characteristics. Tt optimizes the ut1lization of U,5. spade, electronics, ootical and computer teahnology for advanced, integrated and low cost manbing.
