system for airial 
surveying. 
large-scale 
A great number of functions for 
creating digital DPS "Delta" has a 
convenient human-computer 
interface accomplishes 
superimposition of vector- and 
raster-images, realizes fast screen 
regeneration on passing from one 
part of stereopair to another, 
allows to work in interactive mode 
with a large number of entities. 
DTM transformation into a digital 
map is accomplished in graphic 
mapping editor, which allows to 
correct commited errors, add 
conventional signs and captions to 
DTM, make subject colouration 
of geographical entities. When the 
graphical image is connected with 
individual features of an entity, 
cadastre basedata used during 
preparation of standard data for 
land tenure inventory making is 
being filled. According to the 
basedata structure all the 
characteristic fields can be modified 
by user in compliance with 
requirements to the kind of task. 
Information system has a wide 
range of subject requirements 
which | are directed toward 
interaction with terrain cadastre 
basedata, assures obtaining reports 
tied up to the graphic image of an 
entity on display screen. Thus it 
allows to make a number of such 
standard documents as plan of 
setting land-tenure boundaries and 
to search information by given 
criterion, etc.
