ABSTRACT:
This article dedicated to the features of the use of space imagery and remote sensing data for the various tasks of cartography.
Maps produced by satellite imagery are more modem and accurate outlines of mapped objects that best represent the phenomena are
interrelated and that in the absence of such images in general could not be mapped. There was considered two new directions of
space cartography. The first simulates the cosmic view of the Earth on the maps, which led to the creation of so-called "orbital"
maps. Combination of traditional cartographic map image with aerospace is the essence of the second direction. Remote Sensing,
carried out in a wide range of scales, to update maps of small and medium-size directly from the photographs, not seeking renewal of
large-scale maps. The Technical characteristics of modem space images are suitable for mapping scale of 1:5000 and smaller.
Cosmic digital images opens up new possibilities: reduction of the cost of repeated surveys, the increase in area coverage areas,
reducing the distortions associated with the relief. Therefore, surveying from space can become the main method of updating
topographic maps.
1. INTRODUCTION
Cosmonautics and remote sensing images have made in
mapping the Earth is truly revolutionary transformation.
The main sources of information in remote satellite surveys are
satellite imagery - images of objects obtained as a result of
registration with the great distance of their own or reflected
radiation.
For mapping use are important the properties of these
satellite images, as their huge territorial scope and completeness
of mapping territory. To this have to add simultaneity fulfill
mapping, a sharp reduction of time collecting information and
ensuring a high consistency of created on its base the series of
thematic maps.
The development of radio electronics led to a flight of
aerospace systems for imaging areas, different from traditional
photography, such as television, scanner, radar and thermal
surveys.
The introduction of aerospace methods of creating maps and
the development of automated compilation sheet systems - two
major problems of modem theoretical and practical cartography
generated by scientific and technological revolution.
2. MAIN BODY OF TEXT
Development of space surveys gave new impetus to the remote
methods of mapping. They expanded their capabilities - the
global reach of information, including the previously
inaccessible area of the Earth and the surface of other planets,
regular speed and repeatability of receipt and processing of
information, imaging on the satellite pictures of phenomena that
otherwise could not fix.
Maps produced by satellite imagery, are more modem and
accurate outlines of mapped objects that best represent the
phenomena are interrelated and that in the absence of such
images in general could not be mapped (eg, deep faults on
geological maps).
Using space images allows for control and revision of maps in
part: a) the correctness of the boundaries outlines of areals and
geographical distribution of mapping objects and phenomena;
b) overlay compilation of cartographic representation and the
relative position of objects;
c) the reliability of the content of individual units and maps in
general.
In connection with the aerospace mapping there were
developed two new directions. The first simulates the cosmic
view of the Earth on the maps, which led to the creation of so-
called "orbital" maps. Combination of traditional cartographic
map image with aerospace - the essence of the second direction.
It led to the creation photomaps. Photomap - this printing
impression of photomaps, at which the photo image of the area
obtained by mounting transformed aerospace photography
(Gruenberg, Lapkina, 1991). These photographs, thanks to the
generalization of the optical image passing nature of the Earth
in "natural" form and saving the nuances and details, highlight
the most significant.
In the U.S. there photomap this state, assembled from 569
images obtained by satellite "Landsat". It is reproduced on the
scale of 1: 250000 to 1: 5 000 000 for the different seasons in
different spectral regions. Similar photomaps compiled for the
territory of other countries (Canada, France, Britain, Japan,
etc.).
Modem surveying space materials in the quality and level of
resolution can compete with the aerial photographs as a basis
for large-scale topographic maps, and the problem of updating
topographic maps are generally very successfully solved with
satellite imagery. Remote Sensing, carried out in a wide range
of scales, to update maps of small and medium-size directly
from the photographs, not seeking renewal of large-scale maps.
This gives a great gain in time, in the fullness and present
information, as well as the rapid cartographic provision of major
socio-economic projects.
The modem world is very variable: growing cities, new
settlements, built roads, communication networks, engineering
structures, and new areas of mining, cut down forests.
