Description: Location and names of major streams within Bellevue's map extent, including characteristics. The sources are original digitized stream data, ortho photographs, LIDAR, and field checks.
Description: 2 foot contours were generated by GeoTerra, using 2016 LiDAR from PSLC (Puget Sound Lidar Consortium), supplemented with photogrammetrically-collected breaklines. Breaklines were added along major roadways and significant retaining walls, and the DEM was hydrologically enforced using waterlines. The contours were smoothed and generalized to create a more usable, cartographically-pleasing product. Contours with length less than 60 feet were deleted. (Update April 5, 2017)
