Swath Separation Image

Figure 6 of the Lidar Base Specification. Example of a Swath Separation Image. Overlapping swath differences were calculated using a TIN algorithm. Point-in-pixel algorithm also okay as long as the spatial resolution is coarse enough to contain at least one point from each swath. Pixel colors are based on swath differences using green for 0 cm to 8 cm, yellow for 8 cm to 16 cm, and red for greater than 16 cm.  Continuous RGB values throughout area of overlap make it possible to see patterns in the data. A distinct vertical offset in this dataset is indicated by red pixels in the most central overlap region.
