An orthomosaic is like Google Earth, but way sharper. It is a large, map-quality image with high detail and resolution made by combining many smaller images called orthophotos.An orthophoto, orthophotograph or orthoimage is an aerial photograph or satellite imagery geometrically corrected ("orthorectified") such that the scale is uniform: the photo or image follows a given map projection. Unlike an uncorrected aerial photograph, an orthophoto can be used to measure true distances, because it is an accurate representation of the Earth's surface, having been adjusted for topographic

The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface.

A digital elevation model (DEM) is a 3D CG representation of a terrain's surface – commonly of a planet (e.g. Earth), moon, or asteroid – created from a terrain's elevation data.

A DSM is an elevation model that includes the tops of buildings, trees, powerlines, and any other objects. Commonly this is seen as a canopy model and only 'sees' ground where there is nothing else overtop of it

3D technology in GIS maps is explanatory illustrations that represent the scale of real-world objects. 3D models assist appearance, survey in a large number of different domains

Point cloud scene layers can be built directly from a LAS dataset layer and help support sharing 3D point cloud content across the platform.
