Land Use, complete ORMGP coverage 2023

Description

The Southern Ontario Land Resource Information System (SOLRIS) version 3.0 surface has been expanded and infilled in the northern regions where the original layer remains incomplete. The process was necessary to obtain a contiguous surface covering the greater ORMGP jurisdiction.

Methodology

• Data Source - Southern Ontario Land Resource Information System (SOLRIS) 3.0
  • See source metadata.
• Data Source - Agriculture and Agri-food Canada Annual Crop Inventory (2013)
  • See here.

• Rasterization
  • SOLRIS and the AAFC-ACI rasters were re-projected (EPSG 3161) and rasterized at a 15m resolution.

  • The AAFC-ACI codes were reclassified to SOLRIS codes and use as infill in the northern extents where SOLRIS is unavailable.
