The mosaic from the BAT images showed better edge matching than the mosaic from the modified model airplane images, and the BAT image mosaic displayed perfect overlay with the DOQ. We also created a digital elevation model (DEM) from the 8 images (Fig. 10). There was lack of overlap between the 2nd and 3rd image, where no elevation values could be generated. The image orientation shows that the UAV was off-course from the rest of the image strip. The pitch value was 12 degrees for the 2nd image, and it appears that wind had affected the UAV. Although the DEM accuracy has to be assessed in more detail, lower elevations in ditches and higher elevations in vegetated areas are depicted correctly. Several artifacts are probably due to the lack of sufficient ground control.
