A number of geoinformatics actual
problems are considered: building of the Knowledge Base about the Earth,
multilevel base of spatial data, geoinformational simulation of terrains, a
geoinformational securing of terrestrial and air navigating, geoinformational education.
Geodesy and Cartography Federal Agency, the Topographical Service of Russian
Federation Armed Forces are directed on the solution of these problem efforts.
Combination of geoinformational
technologies for the Knowledge Base building about our planet and country is
proved. It is necessary for science, economy, social sphere and defense
development. Knowledge of the processes existent in the Earth core, mantle,
crust, hydrosphere, atmosphere and biosphere, are integrated on the basis of
electronic map System. A mainstream is multi-dimensional existential simulation
and mapping of situations and places with usage of electronic maps and space
maps.
Specific features of electronic
marine cartography, the main of which is necessity of the sea-bottom relief and
marine water column description are considered. It leads to necessity of special
algorithm usage for their description, frames of the information storage and methods
of its search. Approaches to the solution of the electronic marine cartography primary
goals are assumed.
Approaches to integration of the
space information on the basis of cartographical representation in different
scales and with usage of multilevel base of space data are described. The list
of the software products is resulted, enabling to form complicated intellectual
systems, among others, on the basis of the above-stated conceptual approach
affiliation. The procedure of the space information integration on example of development
problem-oriented GIS experience is stated, paths of its
up-dating, refinement and replenishment optimization processes are represented.
Requirements to geoinformational
models of terrain are formulated. The basis of geoinformational simulation is
the informational and analytical bank of geographical knowledge constructed on
three-dimensional models and electronic maps. Relief simulation methods and
analytical processing with usage of the hardware-software complex for the
Internet-mapping allow to construct the optimal map of the Earth surface and to
use the geospatial information about lithosphere. Requirements, principles and
methodology of building three-dimensional models of terrain are stated. Usages
of space simulation of terrain is considered.
The System of electronic maps as
data ware for GIS is considered. Electronic aviation maps entering in this system provide
air navigation problem solving. Priority directions of GIS application in terraneous, air, marine and space
navigation are formulated.
The contents of courses on problems of global mapping and geoinformation
technologies are described.
