Influence of new technologies
on the work with Geo-spatial
Associate prof. Katsko S.Yu.
The number of tools to
geo-analyze is growing
To use it we

16. Electronic cartographic image
Cartographic image visualize the quality of real
objects and phenomena, as well as their forms,
sizes, location, and semantics.
A computer-visualized cartographic image is a
pattern-based and can be generated, scaled,
generalized, metrical in particular projection,
oriented to visual perception of the person.

19. Geocoded databases
The advent of geoinformatics has provided for
data transferring of spatial objects and
phenomena from the cartographic image to
geocoded databases and generating the
geoinformation (digital) terrain model (GTM)
20. Digital map
The person “teaches” a computer to draw an
analogy between database records and
As a result, the computer gets a possibility to
perform those metrical and analytical operations on
user’s request, which only the person was formerly
able to perform them on a traditional map.
Accordingly, digital map is appeared.
A digital map is defined as a dynamical object. It is
formed by software as complex of GTM and
electronic cartographic image.
21. Terrain models
3 computer terrain models are made in
geoinformation model (GTM);
electronic map (EM);
digital map (DM).
