The image below represents an ideal data collection courtesy of Morgan from New Zealand. The flight is over mountainous terrain and has large areas of homogeneous ground cover. The image footprint polygons are visible and highlight the overall quality of the data collection. Morgan provides some additional information, and tips for other operators:

DroneMapper has implemented blending and smoothing algorithms in order to eliminate or at least significantly minimize the appearance of seamlines in orthomosaics. Figure 1) shows a field imaged in the NIR with seamlines apparent throughout the field. A seamline detection algorithm was utilized to identify edges (shown in Figure 2) between processed tiles and apply a blending or feathering of …
