to have a certain overdetermination, i.e. control for absolute accu- 
racy. The residuals at the control points allow the analysis of the 
geometric quality reached in the whole process. 
5. Results 
5. 1 Orientation Procedures 
At the Federal University in Curitiba many LANDSAT "models" have 
been processed at the Planicomp. The results reported here are 
from a Master Thesis (CANEPARO 1983) with geoscientific background, 
analyzing only a very small image section (aprox. 40 km x 40 km). 
Consequently, the image geometry is very good, anyway better than 
it could be expected for a full scene.

Table 1: Orientation record 
Table 1 shows the orientation record. Plotting scale at the table 
is 1 : 100 000, photo scale is 1 : 1.150 351 (Pixel size 50 um 
corresponds to 56 m), determined via ground control, just as flight 
height (962 km) and the coordinates of the perspective center 
(XG0, YGO, ZGO). The parameters of relative orientation like
