{0><}100{>Existing Existence of geoinformatics
in a complex of sciences about the Earth as a new scientific discipline
and its close interaction with
cartography in processes of elaboration and analysis of the spatial information
demands reconsideration of a map role in the life of modern society.<0}
{0><}100{>In traditional
cartography the analog figurative-sign cartographic model visualized earlier on
a paper, and in modern conditions also on technical means, for subsequent use
is created.<0} {0><}100{>Thus the
geoinformation is completely included in the geoimage, perceived and used
directly by the person for processing and the analysis. <0}
Side by side with
geoinformatics there was a geoinformation model of
data in the digital form in which geodata contain in a database and can be used
for the computer analysis and processing, both without direct interaction with
the user, and with participation of the person by means of the cartographic geoimage which acts as a tool of the user interaction and a
computer (the original interface) as means of processed geodata
visualization.<0} {0><}100{>Thus the map loses the former function of storehouse and a
source of the geoinformation, but gets new function of available geoinformation
model original presentation and geodata bases.<0}
{0><}100{>As a result of
distinctions researches between different models of geodata
visual representation a number of analogue (paper) distinctive properties,
raster and vectorial electronic geoimages are revealed:<0} {0><}100{>Limitation of the content, feature of symbols, distinctions during
generalization, etc.<0}
{0><}100{>Today electronic cartographical geoimages are generated in
personal computers, notebooks and pocket computers, in GPS devices, in mobile
phones in special user terminals, electronic boards at stations, at the
airports, etc. Creation and development of business, work of structures of the
government, realization of navigation, sea and ground transportations, etc. are
not thought any more without their use.<0}
{0><}100{>Specificity of such image perception is shown in the approach
distinct, from traditional cartography to resolution of conflicts between
requirements of their visibility and readership:<0} {0><}100{>Instead of one map a series of cartographic images and dynamic
generalization, both geometry, and semantics of the electronic maps are used,
allowing to provide greater visibility and readership on small video screens.<0}
{0><}100{>In precomputer epoch the basic users of maps were basically experts
of various branches of economy (designers, geologists, military, etc). In
connection with difficulty of map distribution the population access to them
have been limited.<0} New technical opportunity {0><}100{>occurrence of
granting access to electronic maps (Internet) and means of their reproduction
promote popularization of electronic cartographic images among wide layers of
the population.<0} {0><}100{>For the first time the map becomes a mass source of
information, original « the second writing », providing wide disseminations of
information about spatial properties of the world encircling us.<0}
