Orthophoto
Orthophoto is a digital topographic product which has a great wealth of information registered on the aerial image, but also all measurement capabilities of topographic maps. Selection of the appropriate resolution of the digital orthophoto (DOF) ie. pixel size in the field, provides a level of detail and accuracy that is required for specific purposes. On the other hand, selection of proper altitude of aircraft means an optimal balance between demands for DOF quality and its price. According to the client's requirements, timelines and required accuracy MapSoft can produce:
- „fast“ orthophoto – based on automatic procedures – available in short time after finished flight missions and
- „pure“ orthophoto – produced using verified DTM, seam lines, … - it takes more time.
