Sample results from Bainbridge Island LIDAR survey



1) Comparison of standard USGS photogrammetrically-derived topography with LIDAR topography. All views are of same 2-km-wide area. Note how photogrammetrically derived topography (A and B) fail to show that drainage from small basin in left-center of map area is into north-flowing creek just to right of center.

A. Primary source: USGS 1:24K contour topography

B. Shaded-relief image from standard 10m DEM derived from 1:24K contour topography

C. Shaded-relief image from LIDAR DEM of same area
