| Product description | Aerial survey photos of the Czech Republic. Photos from 1936 to 2002 were acquired by Ministry of Defence and Armed Forces of the Czech Republic, more precisely by its predecessors. Colour aerial survey photos, acquired from 2003 until 2010 in cooperation with CUZK and Ministry of Defence, are digitized images from analogue sources. Digital colour photos, which were acquired from 2010 in cooperation with CUZK and Ministry of Defence, are provided together with an image in NIR band. Historical photos (approx. 770 thousand photos from 1936 - 2002) are made available gradually, depending on the progress of the digitalisation. In addition, each year photos of a half of the Czech Republic are taken. Aerial survey photos are acquired by central projection, therefore they are not orthophotos and it is not possible to use them directly for measuring spatial relationships among geographical objects. Aerial survey photos can be used for measuring spatial relationship with the use of special photogrammetric methods. | |
