| Abstract | Airborne SAR imagery from the Intera Technologies Ltd., STAR-1 system, along with Landsat TM, airborne MSS and SPOT data were acquired for an experimental site near Swift Current, Saskatchewan. The
STAR-1 data were acquired at three difference look (flight) direction. The primary objective of this study was to determine the relationship between radar backscatter and cultural practices, in particular row direction. A Digital Terrain Model
(slope, aspect and elevation) was used to establish which backscatter variations were mainly due to topography. In addition, the complementary role of SAR and visible and infrared data was evaluated using the multi-sensor data set. digital
classification accuracy along with the results from feature selection algorithms were used as evaluation criteria. |
