the complex inventory documentation /which contains planimetric 
maps, vertical and horizontal cross-sections, elevations, 
frontages and views of the roofs/ or fragmentary documentation 
/elevations and/or frontages only/. 
In the first case /for complex inventory documentation/ stereo 
phot o gramme trie methods have to be used* Therefore photogrammetrie 
cameras and stereo cameras as well as plotting machines /and/or 
stereocomparators/ and orthophoto-projectors must be available* 
For the second case /fragmentary documentation/ single image pho% 
togrammetric methods can be applied and only photographic /non 
metric/ cameras and devices for rectification purposes should 
be accesible* 
All technologies involve two stages: 
- field work, and 
- office work* 
Field work combine: 
a/ project of photo-taking /distribution of camera stations and 
control points/, 
b/ marking /painting/ onx the facade control points /if necessa- 
ry/, 
c/ geodetic survey of basic network including control points and 
camera stations, 
d/ photograph-taking /outside and inside of the monument/* 
Usually fild work includes also direct measurements of some 
details, which are not visible on photographs* 
Office work in all technologies depends on presentation of 
results and qquipment available* Always the sections of stable 
paper or transparent material for cross-sections /vertical and 
■horizontal// and elevations are needed* All points of network 
are plotted on these sections* If necessary transformation of 
control points to the plane of facade is computed and next points 
are plotted* Control points plotted on vertical cross-sections, 
horizontal cross-sections and on the elewations make this docu 
mentation comparable, and therefore the same control points must 
be carefully plotted on both these documentations* 
Using stereo-photographs and plotting machine the above mentioned 
documents can be partly plotted from one model* Before starting 
to plot, the machine should be precisly-tested and rectified* 
In the case when photographic result is wanted - orthophoto-pro- 
jector or rectifier must be accesible* V/hen all the orientation 
elements of the photographs are known it is not difficult to set 
up a stereo-model and then to scale and level it according to 
the plane of the facade* Line map needs plotting* The other 
office works in the orthoprojection method after connection the 
orthophotoscope and plotter, consists in profiling and scanning* 
If necessary the same stereo-model /used in this case for produc 
tion of the orthophoto/ - can be measured for line-plotting of 
the same details on facade /window or door oppenings, missing 
plaster, or ports of the wall/ or for drowing horizontal cross- 
sections on each storey, as v/ell as for drowing indicated verti 
cal cross-sections*
