Aerial photographs Liechtenstein (1964 and 1970)

The data set consists of digitised aerial photographs of the so-called photogrammetric plans from 1964 and 1970, respectively, on which known boundary signs were marked and evaluated at a scale of 1:2000 (so-called aerial photographs, cadastral plans). The aerial photographs were digitised using an aerial scanner. The images are not georeferenced (no external orientation available), but are suitable for photogrammetric analysis or can be used to create an orthophoto if required.
