收藏资源简介:
This Bridge feature layer is comprised of features identifiable in the orthoimagery and Lidar point cloud collected for Leon County, FL in the Spring of 2018. The delineation of the bridge features in this layer reflects ground conditions at the time of source data acquisition. Acquisition Information: 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.
