Topo Creation and Topo Projection

The video introduces two tools, “Topo Creation” and “Topo Projection,” for working with topographical surfaces. The “Topo Creation” tool allows users to pick points on a grid, creating a topo surface based on those points. The presenter emphasizes the importance of selecting more points in depression areas for accuracy. The “Topo Projection” tool is demonstrated as an alternative, useful for projecting an existing topo surface onto a point cloud. This method is presented as a time-saving and convenient approach compared to manual point adjustments.
