Results of the pilot project on satellite-based monitoring of situation with floods in Sverdlovsk Region were summed up. The project was carried out by the specialists of the Space Monitoring Center of the Urals Federal University. This study materials were provided to the Territorial Center of Monitoring and Emergency Response of Sverdlovsk Region, which specialists gave positive assessment of the possibilities of operational use of space images of different resolution for analysis of water bodies status and for detected of flooded areas.
A complex (radar and optical) space imagery of high and middle resolution (3-60 m) was applied for monitoring the floods progress. Satellite data in direct reception mode were received by the “UniScan-24” ground station of the Urals Federal University and еру specialists of this university conducted processing and analysis of the images.
For thematic solutions the data of Kosmosnimki.Ru geo-service was used in addition to the university-based Space Monitoring Center’s tools; a thematic geo-service “Kosmosnimki – Sverdlovsk Region” was created operating in closed mode. The application of web-technologies enabled to practice quick access to project data and to conduct express-analysis of the imaging results.
47 scenes were received for monitoring the floods in Sverdlovsk Region in March-May 2011: EROS A (5 сцен), EROS B (4), SPOT 5 (7), SPOT 4 (13), RADARSAT-1 (18).
For detailed analysis of the floods the areas, located in Slobodo-Turinsk Region on Tura River (Krasny Yar, Barbashino, Zhirykovo and Makui villages) were selected. Within the frames of this project river width changes during the snow cover melting, general area, covered with water and the condition of the infrastructure impacted by the flood, including roads, bridges, construction sites and residential areas and arable lands were assessed.
In 2012 there are plans to conduct floods satellite-based monitoring on the rivers of Sverdlovsk Region with due account for the results of this pilot project.
More information about handling RS data at Urals Federal University is available in the magazine “Earth from Space – the Most Effective Solutions”, issue №9. Also, one may learn more about the current activities and plans of the Urals University specialists during the 5th International Conference “Earth from Space – the Most Effective Solutions” (November 29 – December 1, 2011, Moscow Region “Vatutinki” recreation center).
REFERENCE:
Space Monitoring Center of the Urals Federal University was open in March 2011. It consists of the “UniScan-24” ground receiving station built on national technology and developed by ScanEx RDC and a laboratory of geo-information technologies and processing of Earth remote sensing data. The Space Monitoring Center ensures operations in the mode of direct reception of data delivered from Terra, Aqua (MODIS), SPOT 4 and RADARSAT-1 satellites. “UniScan” station is planned to be upgraded later on to receive data from other RS satellites.
