2008 LiDAR - Reflective Surface

공공데이터포털

Reflective Surface Light Detection and Ranging (LIDAR) Data for Washington, Dc at 1 meter resolution. Reflective surface data represents the DEM created by laser energy reflected from the first surface encountered by the laser pulse. Some energy may continue beyond this initial surface to be reflected by a subsequent surface as represented by the Last Return data.

2009 LiDAR - Intensity

공공데이터포털

Intensity Light Detection and Ranging (LIDAR) Data - 1m resolution. Intensity information is captured from the Reflective Surface pulse and indicates the relative energy returned to the sensor as compared to the energy transmitted. The Intensity image is not calibrated or normalized but indicates differences in energy absorption due to the the interaction of the surface materials with laser energy at the wavelength transmitted by the sensor.

2014 LiDAR - Intensity

2008 LiDAR - Last Return

공공데이터포털

2008 Last Return Light Detection and Ranging (LIDAR) Data for Washington, DC at 1 meter resolution.

2004 LiDAR - First Return

공공데이터포털

First Return Light Detection and Ranging (LIDAR) Data - 1m resolution. The dataset contains locations and attributes of first return elevations in meters. LIDAR data provided by the Joint Precision Strike Demonstration Project Office of the US Army contained bare earth rasters. This raster contains elevations of all structures, tree canopies, and bare earth.
