SWISSIMAGE HIST
The orthophoto mosaic SWISSIMAGE HIST is a composition of historical (before 1998) black and white aerial photographs over the whole of Switzerland with a ground resolution of 50 cm.

The historical (before 1998) black and white Orthophotomosaic of Switzerland
Images that have been freed of their distortions and therefore show a uniform scale over their entire surface, are designated as orthoimage. They can for instance be overlaid with other geodata and serve as a basis for accurate measurements of coordinates, distances and surfaces.
Applications
The field of applications of orthophotos is as various as the content of its underlying aerial photographs.
The historical dimension of SWISSIMAGE HIST and the possible comparison with newer orthophotos make it an ideal basis for studies on the evolution of natural and built environment.
