Aerial photos

Our aerial images are vertical or oblique high-resolution landscape photographs. They contain a great deal of information and are used as a valuable source for identifying dynamic processes, as well as for documentation and planning purposes.

Their main purpose is to serve as the basis for updating the National Map and producing the SWISSIMAGE orthophoto mosaic. The photos encompass the entire country and are taken at regular intervals. 

The scale of the images usually varies between 1:20,000 and 1:30,000. They are available in black and white for the period from 1927 to 2003, and in colour since 1998. 

One section of the collection contains all aerial photos that were taken in order to meet the needs of various federal inventories (meadows, moorlands, dry pastures), for monitoring glaciers or documenting natural disasters (storms, floods, avalanches, rockfalls, landslides, etc.), and for a variety of other special requirements. They are available as colour, colour infrared or black and white images at scales ranging in scale from 1:3,000 to 1:40,000. 

Digital cameras have been used for taking aerial photos since 2008. These devices scan the landscape in strips and all images are available in digital form only.
