Vertical aerial photographs were taken on Joal spit using a Canon EOS 5D Mark II camera and full frame sensor embedded in a gyroplane. A first range of treatments under Agisoft PhotoScan software has generated an orthophoto with 5 cm resolution and a
digital surface model (DSM) with 20 cm resolution. A second range of treatments allows, using ArcGIS® software, the assessment of the vertical accuracy of the DSM, comparing it differentially with a topographic survey previously conducted in the same site with Very High Resolution Real Time Kinematic (RTK) Differential Global Positioning System (DGPS). The results of this assessment are analyzed and discussed.
