This is a great tool for comparing LiDAR elevations to survey, especially on projects where our survey extends are limited and we’re forced to adjust elevations in the terrain upstream and downstream of the survey to more accurately simulate the earth’s surface. If we know how far the survey is below the LiDAR, that gives us an idea of how to adjust the terrain upstream and downstream. Great video Kyle!
