RADAR, GEOGRAPHIC TOOL.

Examination of representative and recently declassified samples of imagery from the type of radar developed especially for reconnaissance and mapping purposes by the military, the Side-Looking Airborne Radar ("SLAB"), indicates that SLAB images look very much like medium-grade aerial photos and will serve the following types of geographic tasks even better. 1) Tasks which require an overview of subcontinental magnitude. 2) Tasks which require an overview in which careful timing is critical. 3) Tasks which require an overview with maximum economy of time and money.
