Lidar Base Specification v. 1.3: Figure 3. Designed double coverage collection, cross-flights with 20-percent overlap. Four overlapping swaths, shown in green, red, cyan, and magenta are shown in this example. The lower cyan swath was erroneously flown too far south, causing the data voids shown in blue. Because the design of the project was to achieve the required aggregate nominal pulse density through cross-flight double-coverage, the blue areas that are not covered by both a horizontal and a vertical swath are considered data voids, which are grounds for rejection of the project.
