Description

Received from the Ontario Ministry of Natural Resources, the Digital Raster Acquisition Project (DRAPE) imagery was collected during leaf off conditions between April 28th and June 7th, 2014. Fugro acquired the Digital Imagery with sensor Leica geosystems ADS100 Digital Camera systems, including inertial measuring unit (IMU) and dual frequency airborne GPS were used for the digital image acquisition.
