True Orthophoto / Orthophoto

Orthophoto/True Orthophoto in detail

Orthophotos are created by correcting the distortion of aerial photographs. This combines the geometric accuracy of a map with the level of detail of a photograph. They are ideally suited for planning purposes, cadastral surveys, and GIS applications.

The crucial difference lies in True Orthophoto: While in classic orthophotos prominent objects like houses, trees, or bridges can appear tilted in the image, they are displayed correctly in True Orthophotos. This is achieved through significantly higher image coverage (80%/60%) and calculations based on precise surface models (DSM).

This eliminates areas with no visibility, creating a continuous, seamless image of the Earth's surface – even in densely built-up urban areas or complex infrastructure zones. True orthophotos thus provide a particularly realistic basis for analysis, planning, and simulations.
