Impervious Surfaces 2018

TLCGIS regularly uses digital orthophotos and planimetric/hydrographic/topographic data to support regulatory functions, land management and acquisition, planning, engineering and habitat restoration projects. This dataset is part of a regularly scheduled update of LiDAR and digital orthophotography products. The dataset was created from source imagery acquired by a Trimble TAC80 natural color digital camera and LAS data acquired by a Optech ALTM HA500 (Pegasus) LIDAR sensor from January 18, 2015 to February 5, 2015. The dataset was updated using source imagery acquired by a LEICA ADS100 digital mapping camera on January 30-31, 2018, and an LAS dataset acquired by a LEICA ALS80 HP LiDAR system from February 5 through April 25, 2018.
