The purpose of the tender is to create the necessary high quality stereo aerial photos in digital form, without blurring effects and with a contrast and brightness sufficient to distinguish details and objects corresponding to actual ground sample distance (GSD) of 15 cm and optional 10 cm in certain parts. The aerial photos must be acquired during springtime in a very short timeframe from March to May. The results of the production based on this tender will become input for both ortho photo and vector-map production. The contract is 2 years with possible for prolongation for up to an additional 3 years. To ensure the entire country is acquired with digital aerial photos, the contract will be split into 5 more or less identical lots based on how long time it will take to acquire with a standard Plane and large scale camera, in this tender called acquisition unit (AU).
