The number of tools to geo-analyze is growing
To use it we need a good

New Trend
All for users!
Geo- in Web 2.0

Geoinformation is coordinate information on geospatial and its facilities.

geoinformation cartography
a new look at the meaning of “cartographic image” in regard to its displaying, perception and
availability in new conditions
Cartographic image

15
Cartographic image as a product
16
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.
Electronic cartographic image

Electronic map consists of graphical primitives
digital presentation of graphical elements:pixels and vectors
Traditional and electronic cartographic image

The interaction of man and cartographic image
Traditional cartographic image
Map legend
The person separates the cartographic
objects, comprehends its properties, and
composes the cartographic patterns

Geocoded databases
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 cartographic objects.
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
3 computer terrain models are made in geoinformation mapping:
geoinformation model (GTM);
electronic map (EM);
digital map (DM).
Terrain models
Features of Geoinformation
22
1) is information about a specific geographical area;
2) in the space-time coordinate system;
3) digital form.
