recognizing that the on-line capability to measure and immediately process 
data increases the speed and reliability of photogrammetric triangulation 
T 
and mey significantly improve the organization of routinely performed work, 
recommends that studies of on-line photogrammetric triangulation be con- 
tinued. 
Mathemaricel Aspects of Digital Terrain Information 
The Congress, noting that Digital Terrain Models have been studied for a long 
time and a resolution for continuing those studies was made at the 13th. Con- 
gress, 
recognizing the importance of the results of such studies to practice, 
recommends that further studies, including comparative tests, be performed 
in such relevant areas as resampling and accuracy aspects. 
lmage Processing and Pattern Recognition 
The Congress, noting that the widespread development and application of image 
processing and pattern recognition technology and the involvement of many 
scientific and engineering fields in this technology, 
realizing its great potential for present and future photogrammetry and 
remote sensing, 
recommends that mathematical and numerical aspects of the entire spectrum of 
image processing and pattern recognition as related to photogrammetry and 
remote sensing be studied, and that communication with organizations and 
societies with similar interests be pursued.
