This poster displays map-to-field conformances regarding culvert locations, flow channels and wetland borders for the Alberta Foothills. The map refers to flow channels, flow-stream crossings, wetland borders, and the cartographic depth-to-water (DTW) index, all digitally derived from LiDAR-DEMs at 1m bare-ground resolution, and from provincial DEMs at 10m resolution (interpolated from 30 m). |
