Aerial Cartographics of America, Inc.collected LiDAR for over 681 square miles in Accomack, Dorchester, Somerset,Sussex, Wicomico, and Worchester Counties in Maryland, Delaware and Virginia.The nominal pulse spacing for this project was no greater than 0.7 meters. Thisproject was collected with a Riegl LMS-Q680i Full Waveform LiDAR Sensor whichcollects an intensity value, GPS Week Time, Flightline and echo numberattributes for each discrete pulse . Dewberry used proprietary procedures toclassify the LAS into an initial ground surface. Dewberry used proprietaryprocedures to classify the LAS and then performed manual classificationsaccording to project specifications: 1-Unclassified, 2-Ground, 7-Noise,9-Water, and 10-Ignored Ground due to breakline proximity. Dewberry produced 3Dbreaklines and combined these with the final LiDAR data to produce seamlessDTMs, DSMs and hydro flattened DEMs, for 833 tiles (1500 meters x 1500 meters)that cover the project area.This is a MD iMAP hosted service.
