The 2D mapping is designed to create high resolutions orthomosaics, elevation models, and multispectral indices.
Most larger scale print maps are 2D plan. Every point on this kind of map is viewed from directly overhead. The viewpoint is at infinity so the viewer looks vertically down the Z axis along parallel projection lines.
Rapid 3D Mapping is a stereophotogrammetry technology. The system generates three-dimensional maps by image captures of the terrain from a manned aircraft, helicopter and/or UAV.
