The purpose of the experiment was to validate the radiometric calibration of the spectrometer and determine the georegistration accuracy achievable from the on-board global positioning system (GPS) and inertial navigation sensors (INS) under operational conditions. In order for low-cost hyperspectral systems to compete with larger systems flown on manned aircraft, they must be able to collect data suitable for quantitative scientific analysis. The results of the in-flight calibration experiment indicate an absolute average agreement of 96.3%, 93.7% and 85.7% for calibration tarps of 56%, 24%, and 2.5% reflectivity, respectively. The achieved planimetric accuracy was 4.6 m (based on RMSE) with a flying height of 344 m above ground level (AGL).<\/jats:p>","DOI":"10.3390\/rs4092736","type":"journal-article","created":{"date-parts":[[2012,9,18]],"date-time":"2012-09-18T03:49:33Z","timestamp":1347940173000},"page":"2736-2752","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":139,"title":["Radiometric and Geometric Analysis of Hyperspectral Imagery Acquired from an Unmanned Aerial Vehicle"],"prefix":"10.3390","volume":"4","author":[{"given":"Ryan","family":"Hruska","sequence":"first","affiliation":[{"name":"Idaho National Laboratory, 2525 North Fremont Ave, Idaho Falls, ID 83415, USA"}]},{"given":"Jessica","family":"Mitchell","sequence":"additional","affiliation":[{"name":"Boise Center Aerospace Laboratory, Idaho State University, 322 E.
