City of Tacoma GISThis layer's geometry has been simplified to make it easier to display on maps and to improve performance. The 7-class land cover dataset was generated using object-based image analysis. Ancillary datasets were incorporated into the analysis to aid in the object classification process. The ancillary datasets used were a rasterized lidar point classification, lidar height products, imagery derived vegetation indices, publicly available open street maps layers, and publicly available impervious Ecopia 3-ft raster data (2021-2022). Automated clean-up routines were developed to ensure feature continuity, reduce noise, and classify streets. A quality assurance process was used to ensure that all data were appropriately classified at a 1:1000 scale. Where the automated classification failed, heads-up digitization was used to correct the appropriate classification. The minimum mapping unit for the land cover classification is 200 square feet. The land cover data follows a canopy dominant classification scheme where features are classified from an aerial perspective. Therefore, features that are obstructed by canopy will be mapped as the canopy class.
