This page covers the many small lidar surveys conducted by King County after the comprehensive 2002 survey, through 2012. The only rasters here are bare-earth. The 2009 raster was created by the PSLC from a King County raster.
LAZ files were added these pages, and we are trying to figure out the las and lax files.
