This competitive tender has been divided into 3 subprojects; see the list below for details of the subprojects and the river stretches.
The map available in Annex 6.2 shows in more detail which areas must be covered.
Riverbed mapping of rivers in Vestland and Møre og Romsdal County: A: 25 km stretches of the rivers Ørstaelva, Valldøla, Jostedøla and Oselva B: Option: 30 km stretches of the rivers Nesstun and Apeltun.
Riverbed mapping of river in Trøndelag County: 21 km stretch of the river Orkla.
Riverbed mapping of rivers in Rogaland County: 49 km stretches of the rivers Vikedalsåna, Suldalslågen, Frafjordsåna and Dirdalsåna.
The subproject 1B are options. We suspect that these rivers will be difficult to collect good data on, due to overhanging vegetation, parts of the rivers are canalized, and it is in an urban area. However, these rivers are important to us, and we want to see what kind of data collection we can achieve here.
Options: In all projects, we ask for the price for full coverage for ALS-data collected, as an option.
