Lidar data were acquired when water levels within the park were historically low. Based on results from the pilot study, our team, supported by our subcontractor Leading Edge Geomatics, co-mounted a Riegl VQ820G topobathymetric lidar sensor, a Riegl LMS Q680i topographic sensor, and a small digital camera in a Piper Navajo aircraft. By utilizing this unique multi-sensor, high-density topobathymetric lidar technology, we were able to acquire both terrestrial near-infrared wavelength and submerged green-wavelength topography data. Prior to collection, extensive ground surveys were performed to calibrate and test the lidar. The data collected will be used to assist USGS and NPS in environmental management of the park, including initiatives to address sea level rise, and help increase the predictive capability of hydrologic models and improve understanding of the park’s diverse habitats and drainage characteristics.
