| Abstract | Mapping tillage activities, and the corresponding crop residue cover, is important for monitoring the adoption of conservation tillage practices and for quantifying wind and water erosion. Previous
studies have demonstrated that remote sensing data can provide information on residue and tillage management practices. To determine the role of RADARSAT in mapping these practices, SAR imagery and corresponding ground data were gathered over a site
in southern Manitoba in October of 1996. No-till surfaces could be identified on imagery collected at shallow incidence angles and radar returns were affected by the type of residue on these surfaces. Using a second data set and a change detection
approach, tillage events and harvesting activities were detected using Standard Mode RADARSAT data. Although further investigation into this application is required, this study concludes that RADARSAT can provide some information critical to
determining soil erosion risk. |
