The Use of Multi-beam Radarsat-1 for Terrain Mapping
نویسنده
چکیده
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 and a measure of moisture balance in the study area. These features are highlighted due to the interaction of incidence angles and look directions within and between the two beam modes.

Difficulties in acquiring a complete aerial photography coverage on a regular basis in the Brazilian Amazon due to adverse environmental conditions affect the quality of the national topographic database. As a consequence, topographic information is still poor, and when available needs to be up-dated or re-mapped. In this research, altimetric information derived from RADARSAT-1 (Fine and Standa...

متن کاملTerrain Slope Correction and Precise Registration of SAR Data for Forest Mapping and Monitoring
SAR data acquired over hilly terrain show geometric and radiometric distortions due to the sidelooking configuration of the radar sensors. These effects usually lead to a distortion of the useful backscatter information related to land cover or bio-geophysical parameters. Post-processing approaches to remove such distortions are very important to broaden the application possibilities of radar r...
متن کاملFusion of Modis and Radarsat Data for Crop Type Classification — an Initial Study
Agricultural land use mapping and change detection are important for environmental assessment and crop yield estimation. An effective mapping and change detection of crop land use requires large image coverage with sufficient resolutions in spatial, spectral and temporal dimensions. But few earth observation sensors can solely collect image data that meet all these requirements. The MODIS (Mode...
متن کاملAssessment of Terrain and Land Use/Land Cover Changes of Mine Sites using Geospatial Techniques in Plateau State, Nigeria
In this paper, we report a geospatial assessment of the selected mine sites in the Plateau State, Nigeria. The aim of this work is to determine the impact of mining on the terrain as well as the Land Use/Land Cover (LULC) of the host communities. The Shuttle Radar Topographic Mission (SRTM) is used for the terrain mapping. The derived impact of mining on LULC between 1975 and 2014 is determined...
