Land Cover Classification 2020 (raster)

A land cover classification for Metro Vancouver plus a 5km buffer, providing a contiguous surface mapped to broad biophysical classes. Created using PlanetScope 5m multi-spectral satellite imagery and full feature LiDAR data (wherever available). The imagery dates from August 2020.

LiDAR data were obtained from the Metro Vancouver member jurisdictions where available. As a result, the LiDAR data used in the project represents a mosaic of vintages (from 2016 to 2020). LiDAR data were available for much of the study area, including the Capilano and Seymour watersheds; however, none were available for the rest of the Mountain Wilderness subregion. Three terrain surfaces were generated from the LiDAR data: a digital elevation model (DEM), a digital surface model (DSM) derived from first return values from each LiDAR pulse, and a canopy height model (CHM), which includes vegetation and building heights. These surfaces were resampled to a 5 m resolution to match the PlanetScope imagery.

A random forest approach was selected to perform a supervised classification of the study area. This iterative process generates hundreds of unique decision trees, each producing a classified image. The benefit of using a random forest algorithm is that the ensemble method compensates for any model weaknesses present in the individual trees; thereby, producing better classification results. Additionally, it is a data-driven approach that is flexible enough to accommodate a variety of predictor variables and can be easily scaled to fit the study area. For this project, a random forest model was built to match the class framework and definitions used in the 2014 Land Cover Classification. Table 1 below summarizes the land cover classes and associated definitions.
