Contours 50ft 2016

2016 10-foot contour data(queried to display every 50 ft) derived from 3ft pixel bare earth rasters for the Seattle Area that were acquired and processed 02/24/2016 -03/28/2016 by Quantum Spatial (QSI). Displays data from IMAGE.Contour_2016 with the following definition query: Contour IN( 0 , 50 , 100 , 150 , 200 , 250 , 300 , 350 , 400 , 450 , 500 , 550 ). This layer does not display when zoomed out beyond 45,000. Labels are based on the attribute Contour. Because of the size of this dataset, we do not recommend trying to download it.
