Applications - The APPS was developed to meet a requirement for rapidly 
locating the positions of objects in support of the U. S. Army. The 
basic concept being that cartographic photography and the associated 
triangulation data provide a convenient source for accurate determination 
of ground positions. The Army plans to use the APPS primarily for locating 
the position and elevation of friendly as well as potential adversary units. 
Other potential applicationsof the APPS which are being investigated are: 
a. Establishing Survey Control 
b. Determination of Range and Azimuth 
c. Terrain Masking 
d. Determination of Slopes 
e. Determination of the Size of Objects 
f. Determination of Areas and Volumes 
There are a number of other related applications whereby the rapid and 
relatively low-cost capabilities of the APPS can be utilized. The only 
constraint is the existence of a photographic data base over the area of 
interest. If that area has been previously mapped from photography, these 
photographs can be used for the data base. 
Future Developments - Future developments should be considered in the 
context of the original concept of the APPS as a simple and relatively 
low-cost application of photogrammetry to the general problem of point 
location. Because of this concept, the APPS approach cannot be considered 
to have the precision of analytical triangulation or ground surveys.
