The system operates from a King-Air 200 aircraft flying at altitudes between 200 and 700 meters with ground speeds between 125 and 175 knots. CHARTS provides a fully operational compact airborne lidar (Light Detection And Ranging) hydrographic and topographic mapping and charting system using infrared 532 nm) laser technology. The CHARTS system also includes a ground-based data processing system for calculating accurate horizontal position, water depth and elevation. Purpose: The purpose of the survey is to obtain the existing near shore bathymetric conditions along Vashon Island.

A unique ground control system (GCS) is required to process the data. The GCS main functions are (1) import airborne data collected onto removable hard drives; (2) perform quality control checks on initial depths/elevations and horizontal positions; (3) provide display edit capabilities; (4) calculate depth/elevation position values for each sounding; (5) output final xyz for each sounding.
