A first point cloud corresponds to the terrain topography during a first time period. A second point cloud corresponds to the terrain topography during a second time period. One or more processors collectively execute instructions to: for each point in the first point cloud, determine a point plane; align the first and second point clouds based on a plurality of plane offset distances; for each point in the aligned second point cloud, calculate a normal direction; for each point in the aligned second point cloud, identify one or more corresponding points in the aligned first point cloud; and generate a third point cloud representing topographical differences. The first point cloud can be divided into a plurality of grid cells and a plurality of graphics processing cores can execute parallel point processing based on the plurality of grid cells."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for evaluating changes in terrain topography over time","description":"Systems and methods for evaluating changes in terrain topography over time are provided.
