LIDAR 2004 Intensity Imagery
Entry ID: lidar_2004_Intense


Summary
Abstract: Light Detection and Ranging (LIDAR) is a method of locating objects on the
ground using aerial-borne equipment. It is similar to RADAR or SONAR in that
the two-way travel time of an energy beam reflected off an object is precisely
measured, but this technology uses laser light instead of radio or sound waves.
This technology has proven very useful in remote sensing of the earth. It can
be used for ... View entire text

Quality Computational Consulting Services, the LIDAR processing vendor, used
proprietary algorithms to remove features and artifacts in the First and Last
Return data that did not reflect true ground elevation. Subsequent quality
assurance testing by Dewberry determined that the data met FEMA and MD DNR
specifications for both vertical accuracy and other consistencies (see QA
report at http://dnrweb.dnr.state.md.us/gis/data/lidar ).
