Canadian Red River Watershed

Project Overview

  1. Crop identification and acreage estimation: Estimates are required end-of-season. An early in-season estimate is desirable.
  2. Residue and Tillage mapping: Monitoring of fields through fall and spring tillage season with minimum requirement of weekly mapping. This aspect of the project targets identification of tillage events and estimates of residue cover and changes in residue cover due to tillage activities.
  3. Soil moisture: Information is required in near-real time (within hours) for watershed and field level estimates of absolute volumetric surface soil moisture and changes in soil moisture. Regional estimates are needed to define risk due to moisture anomalies. These regional estimates are to be provided on a weekly basis.
  4. Crop biophysical variables (LAI): Information is needed frequently throughout the growing season (if possible, weekly from emergence to harvest). LAI estimates are to be assimilated into locally calibrated yield models, and to provide a more quantitative evaluation (relative to NDVI) of crop condition.

The mapping resolution varies from within field to watershed and regional mapping. The timeliness (with regards to growing season) varies depending on the mapping activity.
