Danish KU Forest Heights
Introduction
The Danish University of Copenhagen (Københavns Universitet, KU) - Department of Geosciences and Natural Resource Management — is developing and maintaining a Danish National Forest Inventory map. Latest update was made in 2017 with data sources originating from 2014-2015. The map is generated from national aerial laser-scans along with associated modelling to describe the relation between laser-scans and actual recordings from a number of test areas. Processed forest inventory data is made available at a 25m grid resolution.
Data Applicability and Availability within windPRO
The forest height data are used as input for the dedicated sub-models in windPRO which takes into account the forest impact on the wind flow. This is the displacement height calculator and the Objective Roughness Approach (ORA) tool. Both forest models are available from windPRO 3.2+. The forest data is accessed from the online-services from the ‘elevation grid object’ with data-type set to ‘Heights above terrain (a.g.l) for elements’.
