Catchment Structural Units

This project generated unique numerical codes at the pixel level to provide wall-to-wall coverage of 128 unique Catchment Structural Units (CSUs) codes based on land use-land cover (LULC), surficial geology, wetlands and slope across the Province. The Provincial CSU layer represents the quantification of combined structural influences at an individual pixel scale, as expressed by a specific numeric and text code. These codes reflect the geospatial layers used to represent catchment structure. The CSU data is presented at a pixel resolution of 20 x 20 m and five initial structural layers (i.e., land cover, land use, surficial geology, wetlands and slope). This resolution was chosen to balance detail with computational efficiency. Each class within the structural layers were assigned unique numeric codes of different orders of magnitude.
