Subset of Tetra Cam ADC Imagery
We recently received a data collection courtesy of David Dvorak using the Tetra Cam ADC Multi-spectral image sensor. DroneMapper processed 189 geo-tagged 3.2 mega pixel images into geo-referenced Orthomosaic, DEM, DSM and Point Clouds with an area of 1.6 km sq. The AGL of the flight was 1000 ft resulting in a 15 cm GSD per pixel. Processing time was about 2 hours for this data set.
Accurate DEM construction is still possible using 3.2 mega pixel images:
