numerical radial triangulation gave the standard error + 0,1 mm and 
the precision mechanical triangulation (PMRT) + 0,2 mm with the 
maximum error about 0,4 mm. The Multiplex-triangulation with grids 
gave — after reduction to the same scale — a standard error + 0,5— 
0,8 mm. For the Multiplextriangulation there is, however, not the same 
high demand on the execution of the photography and hence the Multi- 
plex-results shall also be compared with the next group of tests. For 
that group normal photography was assumed and as to inclination some 
systematism in strip V and alternatively less systematism in the four 
strips B. A rigorous adjusted numerical triangulation of strip V gave 
the same standard error — + 0,7 mm — exactly as the mechanical 
radial triangulation and only slightly lower than an approximate nume- 
rical radial triangulation with the standard error + 0,75 mm. For the 
B-strip the standard error was 2- 0,5 mm both in numerical and mecha- 
nical radial triangulation as well as directly calculated from the standard 
direction error, according to the formulas of Reicheneder. 
These strip results are only reported in order to give a comparison 
with some other methods; as a matter of fact MRT is an area-method 
and has the real advantages as such one. 
Further results and analysis of them are to be found in the above- 
mentioned thesis.
