from the imagery and any other available source in other colors, maps can be 
generated which provide a basis for regional planning of a wide variety of 
types at a reconnaissance or qualitative level. Data included are: 
1) The proper names of natural features such as rivers, valleys, 
mountain ranges, volcanoes, islands, bays, lakes and related 
physiographic features; 
2) The proper names of man-made features such as towns, villages, 
dams and reservoirs, arterial roads, railroads, powerlines, harbors, 
airports, etc.; and 
3) Spot elevations of prominent topographic features and valleys. 
Such maps also provide an effective background for overprints of terrain 
information permitting the reader the opportunity to evaluate the interpreta- 
tion. This type of presentation using radar mosaics was developed by Motorola 
MARS and is being used by the Nigerian Department of Forestry for the genera- 
tion of a vegetation map series. The completion of the Radarmaps and 
vegetation and land use maps provides a basis for development and planning in : 
Nigeria which is at present unparalleled in Africa. 
  
Conclusion 
PH.) A289 | —S 8. 
SLAR need not be relegated only to mapping areas plagued by extensive 
cloud cover as it has been demonstrated to be a useful and cost-effective tool 
in all latitudes. Although SLAR is used primarily in reconnaissance studies, 
its shadowing capability and unique responses to target parameters justify its 
utilization for generation of a wide variety of terrain and vegetation data. 
It should be noted that even in areas of relatively detailed mapping, these 
unique capabilities of SLAR have resulted in the procurement of data previously 
unattainable.
