Aerial images swisstopo oblique

About 4,000 black and white oblique aerial photos form a small part of the image collection of swisstopo. There are snapshots of small towns and photos of the atmosphere in the pre-alpine and alpine regions, which were taken during the regular aerial surveys. There are also photos as documentation of natural events and important buildings. In addition to this, numerous stereo recordings were made, covering larger areas in the lowlands, but also details of rock formations. For the positioning of the recordings only the coordinates of the image centre were calculated. Of the approximately 4000 oblique aerial photos over 2,000 are now accessible (June 2018).
