Description: Two-foot contours were created by GeoTerra utilizing existing 2016 Puget Sound Lidar Consortium data and new digital terrain data as collected using stereo imagery acquired on March 19, 2017. Existing 2016 ground-classified Lidar data was reviewed for areas of change using imagery acquired for the 2017 Eastside Aerial Mapping Project. Existing ground-classified Lidar data was updated or edited where changes were identified. In addition, 3D breaklines were collected in stereo to assist in better-defining sharp breaks in terrain where existing ground Lidar data was insufficient to define the ground for contours. The resulting updated terrain surface used to generate two-foot contours is included with this dataset.
