Digital Spring Photography and AT 2025-29

Description

Danish municipalities and Agency for Climate Data (KDS), via the joint cooperation GeoDanmark (http://www.geodanmark.dk), have established a common vector- and raster-dataset as a public geographical ad-ministrative basis for digital management (e-governance) in Denmark. For the maintenance of this dataset, full land coverage of digital spring aerial photos is tendered. The purpose of the tender is to create the necessary snow-, ice- and leaf-free high quality stereo aerial photos in digital form, without blurring effects (clouds, smog etc.) and with a contrast and brightness sufficient to distinguish details and objects corresponding to actual ground sample distance (GSD) of 15 cm and optional 10cm in certain parts. The aerial photos must be acquired during springtime in a very short timeframe during March, April and beginning of May. The results of the production based on this tender will in spring 2025 (and beyond) become input for both ortho photo and vector-map production. Ortho photo and vector mapping are tendered separately at a later time. This service was also tendered in parts or full in 2015 (parts), 2016 (full), 2017 (parts) and 2020 (full). The contract is 2 years with possible prolongation for addi-tional three years, one year at a time. To ensure the entire country is acquired with digital aerial photos, the con-tract will be split into five more or less identical lots based on how long time it will take to acquire with a stand-ard Plane and large scale photogrammetric camera, in this tender called acquisition unit (AU). A new feature in 2025, is the possibility for KDS to swap up to 8 blocks between suppliers for one year at a time, the purpose being to reduce co2 emission and thereby get an overall greener acquisition.
