Orthomosaic Photography
An orthophoto, orthophotograph or orthoimage is an aerial photograph geometrically corrected (“orthorectified”) such that the scale is uniform: the photo has the same lack of distortion as a map. An orthorphoto can be used to measure distances, because it is an accurate representation of the Earth’s surface, having been adjusted for topographic relief, lens distortion, and camera tilt.
An orthomosaic is a series of multiple orthophoto images (sometimes hundreds) stitched together to create a highly-detailed satellite view of an area on a single image.
3D Modeling
Three-dimensional (3D) models represent a physical object using a collection of points in 3D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc.
By using this collection of data points and information the surfaces can be further defined with texture mapping from the imagery.
Elevation Models
An Digital Elevation Model, or DEM, is a visual representation of the changes in elevation along the surface of terrain or structures.
This type of data can be valuable in terrain analysis, precision farming, surface analysis, creation of relief guides, and much more.
