Lidar Base Specification v. 1.3: Figure 2. Designed double coverage collection, 50-percent overlap. In this example, three adjacent overlapping swaths (green, red, and yellow) have been collected. Because the design of the project achieved the required aggregate nominal pulse density (ANPD) through double-coverage, the blue areas that are not covered by two swaths are considered data voids, which are grounds for rejection of the project.
