Dense point clouds are the foundation of nearly every mapping product and consist of a set of points in space representing the surfaces of scanned objects. They can be used for comparison against CAD models, in visualization, and 3D printing applications.
Surface models are a surfaced version of the dense point cloud. This surface provides a complete view of the point data and a more compact, smaller file format for conveying the captured data.
Digital elevation models, or DEMs, are uniformly sampled grids of elevation data. DEMs are valuable as base layers in GIS systems and can be used for terrain visualization, flood modeling, and volume calculations.
Ortho-mosaiced images transform simple aerial photographs into maps. Orthophotos can service as the base layer in many GIS and other mapping applications such as displaying road vectors and contours.
Contour maps clearly illustrate the change in elevation by tracing fixed elevations with contoured lines. These maps provide valuable insight for mapping water flow and drainage.
Volume change maps illustrate changes in terrain over time without the need for a dedicated survey team. These maps are built from ultra dense point clouds resulting in accurate estimates of volume.
