4* Economic aspects of making-up of architectural documentation 
183 
Difficulties rise from the fact, that seperate objects are 
different and it is not easy to compare documents prepared 
using differezit methods. 
Large scale character of architectural documentation works in 
Poland was a reason, that production norms were introduced for 
this kind of work. 
For field work the following coefficients taking in account 
camera orientation and station of the camera are applied: 
- when tilted or averted photographs are taken 1,2 
- when photograps are taken from 3?oofs or balconies 1,5* 
During office work, when rectification is performed other 
coefficients depending on tilt of screen are applied: 
- for angles 10° - 3Cr ..... 1,2 
-for angles 30° ••••• 1.4 
The biggest differences in coefficients are introduced when 
stereometric technique is used and the degree of complication as 
well as variety of interior decoration must be plotted. Then 
coefficients from 0.1 to 2.0 are assigned. 
Let s analyze three main technologies used in architectural do 
cumentation: 
1. Stereometric 
2. Rectification 
3. Orthoprojection 
For each technology, one can distinguish the four following steps: 
I. Preliminary field work /plan of photographs taking, reconna 
issance, marking and measurements of control points/, 
II. Taking photographs /single or stereo/, 
III. Instruments office work /setting-up orientation, plotting, 
profiling and scanning, rectification/, 
IV. Final work /architectonical interpretation, drawings, 
montages, compilation, reproduction/. 
Detailed comparison of the time and costs of individual steps is 
based on documentation at scale 1:50 done by University of Mining 
and Metallurgy in CracOw. All three technologies were used when 
inventory measurements on the ruins of the Krzyztopor castle in 
Ujazd were performed. Photographs was taken with UMK 10/1318 
Zeiss-Jena camera, the plotting was done on Topocart B plotter, 
the orthophotos were produced on Topocart-Orthophot system and 
rectification was performed on SEG V rectifier. The range of 
work contained full documentation: elevations, inferior eleva 
tions, horizontal and vertical cross-sections. Let s analyse 
these parts of documentation only, which were performed using 
the three above mentioned methods i.e. exterial and interial 
elevations. 
When exterial elevations were documented the scale ratio between 
photo and output was 1:4, but for interial elevations 1:1,5 only 
because of height and width of rooms.
