Satellite data

The new direction of space geoinformatics started to progress in Russia and in the world, pertaining to the creation of geoportals and web-map services. First Russian geoportals are Yandex.Maps and Kosmosnimki with satellite geolocated mosaics of largest cities and central administrative regions.

An important issue in a geoportal development is to fill it in with updated space images and to created mosaics from a set of satellite imagery. The solution can be the integration of geoportals and regional centers of operational RS data reception into a unified solid production mechanism.

On March 25-27 the St-Petersburg Central R&D Institute of Robotics and Technical Cybernetics partnered with ScanEx R&D Center to showcase the real-time processing and transfer of space images, acquired from RS satellites, via encoded Internet channels to the customers of the government committee of St-Petersburg.

Earth Remote Sensing Center at the St-Petersburg Central R&D Institute of Robotics and Technical Cybernetics, equipped with the Uniscan ground receiving station provided the RADARSAT-1, SPOT-2, SPOT-4, EROS-A and TERRA data reception. Kosmosnimki geo-service of ScanEx Center was used as a prototype of the regional geoportal. Relevant committees of Leningrad Region and North-Western Federal District administrations can be the potential clients of such geoportal.

Special attention was paid to the possibility of near real-time data reception from the all-weather RADARSAT-1 radar satellite. One of the images of the city and of the dike was acquired on the evening of March 25 during the blizzard with wind blasts over St-Petersburg.
The demonstrated version of geoportal can be used as a catalog for quick search for geospatial data and a tool for assessment and analysis of ecological situation, nature use control and environmental and high risk areas monitoring
