for semi-metric and medium format, whereas negli- 
gible for non-metric and small format. 
5.6 Concerning control information 
* 3196 solutions used minimum control information. 
* 69% solutions used maximum control information. 
* The flunctuation of the results is little when using 
max. control in contrary to min. control (given 
measures as distances and defined verticals) solutions. 
5.7 Photogrammetric restitution results 
Although the main objective of this test has been to 
evaluate the different programs of bundle adjustments 
available, as well as to proof the possibility of using 
amateur cameras for recording with photogrammetry our 
cultural heritage, it should not be forgotten that the 
fundamental application of photogrammetry in the field of 
architecture continues to be that of obtaining graphic 
records. 
Up until the present, only two centers have carried out a 
graphic plotting of the building presented here. As a 
comparative element we have at our disposal a plotting 
previously carried out by the Bundesdenkmalamt using a 
SMK metric bi-camera from Carl Zeiss Oberkochen and 
an analogical plotter. In our case we have used the 
photographs obtained with the Rolleimetric 6006 camera 
and the ADAM MPS2 stereoplotter. For this instrument 
an interface for working directly in Autocad have been 
used. As records of reference, three of the four elevations 
have been plotted, since the two lateral elevations are 
practically identical. By joining the elevations we were 
able to make up a three-dimensional model with which to 
construct perspectives of the building from different 
positions and angles. 
By comparing the results of the analogical plotting carried 
out by the Bundesdenkmalamt with the drawings now 
effected, a similarity may be appreciated both with regard 
to the precision achieved and with regard to the graphic 
result. The most remarkable difference can obviously be 
observed in the lighter weight and greater ease in the use 
of the equipment used at present, particularly with 
reference to the photographic camera, and above all, the 
considerable advantages there are on the availability of 
the results in CAD and with three dimensions recording. 
This whole system provides undeniable advantages, from 
the simplification of data-taking thanks to the use of light 
cameras which are easy to transport and to handle as well 
as to the reduction in control data. At the same time there 
are possibilities of obtaining a graphic quality similar to 
that achieved by means of traditional equipment.
