Canadian Red River Watershed

Operational Implementation Plans

Crop mapping at 30m pixel resolution

  • 2014 growing season crop inventory maps were created (30m resolution) covering all Manitoba as a part of the Agriculture and Agri-Food Canada annual EO-based national crop inventory program
  • Developing spatial data and very accurate EO-based crop identification at 5m pixel resolution: Testing various EO-statistically-based methods and developing methodologies for highly accurate classification of target crops in different parts within the Manitoba pilot area with various levels of landform homogeneity. A journal paper is submitted for publication related to this component.
  • Testing the application of multivariate statistical methods to improve classification of pasture and forage crops from some of the annual target crops within the Manitoba pilot site. Results submitted for publication as a journal paper.
  • Testing, developing and applying geostatistical methodologies for re-allocation of target variables to the Terrestrial Monitoring sampling framework points within the Prairies province based on the results of the pilot sites.
  • Developing spatial databases based on the above methods to estimate value: As discrete data for the location of the samples of the Terrestrial Monitoring Framework, and depending on the variable, and as continuous spatial data.
  • Methods to accurately estimate the area of target major crops based on the stratification of the pilot sites by farming systems   are being tested and developed.

Crop Condition/Stress

  • Collected crop phenology, leaf area index, and biomass over selected fields in 2014.

Soil Moisture

  • With the addition of 3 new stations in 2014, this site currently has twelve automated in situ monitoring stations set up to capture larger scale variation in soil moisture to support calibration and validation of remotely sensed and modelled soil moisture data products. The data from these stations is collected every 15 minutes and transmitted to a central server, where it undergoes a quality control filtering before it is released for distribution.
  • Soil moisture measurements were taken at 5-cm depth weekly over two spring wheat fields, two corn fields, two canola fields and two soybean fields throughout the growing season using a Theta probe.

Crop Residue, Tillage and Crop Cover Mapping

  • Nothing for 2014.

 

Plans for Next Growing Season:

The EO-based 2015 crop inventory map (30 m) resolution will be created for the whole agricultural area (accuracy of crop classes around 85%) covering the JECAM monitoring area. Field work will be done to record crop types for all fields within some of the monitoring sections located in the JECAM monitoring area. Results will be applied to develop methods for very accurate crop area estimations.

Crop conditions will be monitored at weekly time intervals in an area south of the JECAM monitoring site (Figure 1). Methods to derived crop growth stage and harvest status from radar and optical satellites will be developed.

Soil moisture mapping from active and passive microwave is being piloted over this site due to the high quality soil moisture validation available.
