This tender is an open procurement for data acquisition and processing of LiDAR data for revising the Danish Height Model (DK-DHM). The contract is initially for a 2-year period covering 2/5 of Denmark (roughly 17 000 km2) with possibility of a 3-year extension granted annually for the last 3/5 (roughly 26 000 km2).

Data acquisition is to be undertaken in spring/early summer before foliation, have an equal or better point density (4 pts/m2) and processed to meet the geometric and classification qualities of the existing data.

The DK-DHM is part of the Danish Basic Data Programme (https://www.digst.dk/Servicemenu/English/Digitisation/Basic-Data) and was revised last time in 2014/15. Data from the Basic Data Programme is publicly available and can be downloaded from various portals – mapping and height data in particular from Kortforsyningen (http://kortforsyningen.dk).

This tender is an open procurement for data acquisition and processing of LiDAR data for revising the Danish Height Model (DK-DHM). The contract is initially for a 2-year period covering 2/5 of Denmark (roughly 17 000 km2) with possibility of a three-year extension granted annually for the last 3/5 (roughly 26 000 km2).

Acquisition and classification of LiDAR point cloud with point density better than 4 pts/m2, and accuracy better than 5 cm in Z and 15 cm in XY RMSE.

Scannertype must be of rotating prism.

Area will be partitioned into acquisition blocks defined by SDFE to ensure smooth production and invoice flow.

Over a 5 year period the entire country will be covered (the last 3 parts is a possibility via prolongation of the contract see section II.2.7).

Ground Control Points and CORS data is supplied by SDFE.
