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 two-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).
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 /2015. 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 ).

Acquisition and classification of LiDAR point cloud with point density better than 4 pts /m², and accuracy better than 5 cm in Z and 15cm 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 years period the entire country will be covered (the last three parts is a possiblelity via prolongation of the contract see section II.2.7).
Ground control points and CORS data is supplied by SDFE.
