RADARSAT-1 Antarctic Mapping Project: change-detection and surface velocity campaign
TheRADARSAT-1AntarcticMapping Project (RAMP) is a collaboration betweenNASAandthe CanadianSpaceAgency tomapAntarcticausing synthetic aperture radar (SAR).The first Antarctic MappingMission (AMM-1) was successfully completed in October 1997. Data from the acquisition phase of the 1997 campaign have been used to achieve the primary goalof producing the first high-resolution SAR imagemap ofAntarct...
متن کاملComprehensive Annual Ice Sheet Velocity Mapping Using Landsat-8, Sentinel-1, and RADARSAT-2 Data
Satellite remote sensing data including Landsat-8 (optical), Sentinel-1, and RADARSAT-2 (synthetic aperture radar (SAR) missions) have recently become routinely available for large scale ice velocity mapping of ice sheets in Greenland and Antarctica. These datasets are too large in size to be processed and calibrated manually as done in the past. Here, we describe a methodology to process the S...
متن کاملOperational Surface Water Detection and Monitoring Using Radarsat 2
Traditional on-site methods for mapping and monitoring surface water extent are prohibitively expensive at a national scale within Canada. Despite successful cost-sharing programs between the provinces and the federal government, an extensive number of water features within the country remain unmonitored. Particularly difficult to monitor are the potholes in the Canadian Prairie region, most of...
متن کاملSpatial Mapping of Soil Moisture Using Radarsat-1 Data
In this research, a back-propagation neural network was used to retrieve and map the surface soil moisture in Oklahoma (97d35'W, 36d15'N) from Synthetic Aperture Radar data acquired by RADARSAT-1 satellite. In addition to SAR backscattering, different vegetation-related information (vegetation optical depth and Normalized Difference Vegetation Index) have been added as additional inputs to the ...
متن کاملThe Use of Multi-beam Radarsat-1 for Terrain Mapping
Multi-beam RADARSAT-1 satellite imagery has been used as part of a regional terrain mapping program in northern Alberta, Canada. Principal components analysis (PCA) has been applied to ascending and descending standard beam modes with incidence angles of 20-27o (S1) and 45-49o (S7). The resulting components yield imagery that highlights geomorphology, geologic structure, variation in vegetation...
