On May 3, 2016, Aero-Graphics acquired high resolution LiDAR data and digital 3-band stereo imagery over approximately 22 square miles located in Fremont County, Idaho. The LiDAR and orthoimagery deliverables were collected to support the Island Park Reservoir Enlargement Assessment. See the vendor supplied reportfor detailed collection information.

LiDAR and imagery acquisition for the Island Park Reservoir project was performed simultaneously with an Optech ALTM Orion H300 LiDAR sensor and an Optech CS-10000 aerial camera system. The LiDAR sensor and the aerial camera were paired in a customized mount to minimize error and increase accuracy between datasets. Aero-Graphics flew at an average altitude of 2,625 ft AGL (above ground level) and made appropriate adjustments to compensate for topographic relief. The imagery was acquired at a 5.9 cm ground sampling distance with 60% forward and 50% side overlap, collecting 2,579 images over 48 flightlines. LiDAR acquisition was performed with 50% overlap and yielded an average 8.8 points per square meter throughout the project area. The PRF (pulse rate frequency) used for collection was 125 kHz, scan frequency 57.1 Hz, and scan angle +/- 15° from the nadir position (full scan angle 30°).
