them; /magine, has a single file (*img) which is 
described in documentation, but just a very skilled 
user can handle it from outside /magine environment. 
b. When Multiscope perform geometric corrections to 
images, the shape of the pixel remain the same and 
the transformation parameters are written in a file; 
when /magine perform geometric corrections to 
images, the shape of the pixel is modified. 
c. Module TopoLogic and Vectonsation algorithm can 
be compared with Arc/Info — Arc/Scan. The functions 
are similar, but Vectorisation algorithm can perform 
just full automatic vectorisation which is not always 
efficient. In this test, on brown mylar beside leveling 
there were and other elements (raster of populated 
piaces, so.) which need to be erased before 
vectorisation. This was a time consuming operation. 
d. It must be emphased that not all functions from 
parent software were included in this prototype. 
Up to now it was not decided the price for commercial 
purposes of VIRGOS, even the name will be probably 
changed. But, from our survey, the price will be 60% from 
ARC/INFO — Imagine. 
The added value for potential customers might be an 
ready-to-use, user friendly integrated system at moderate 
price, with rich sets of processing for both images and 
vector data. 
4 CONCLUSIONS 
The VIRGOS prototype system, tested by DTM using data 
over Romanian territory, is very good for compiling and 
up-dating of topographic maps for large organizations with 
a certain budget. 
In order to use such a system for compiling and up-dating 
of cadastral maps and plans we consider that it the 
software must be ported to PC's with WINDOWS NT 
operating system. By this way the aqusition price will be 
drastically reduced.
