Current (mid 2019) coverage SR16 - Norwegian Forest Heights. Classified areas are shown with red color - a total of 152 municipalities are covered out of 432.

Introduction

The Norwegian Institute of Bioeconomy Research (NIBIO) is developing a national forest resource map (Skogressourskart, SR16). Currently - summer 2019 - coverage is still being expanded - with the goal to get full national coverage. At this time a total of 152 of 422 municipalicies have been relased as a part of the dataset. The map is generated through automated processing of existing maps, terrain models, 3d-remote-sensing and field-data measurements. The Norwegian forest heights in windPRO comes with a 16m grid resolution. This dataset will be updated as new data become available from NIBIO.

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’.

Technical Details (EMD processed data)

Dataformat: Raster / GeoTiff

Coordinate System: UTM - zone 32N - EUREF89 (EPSG: 25832)

Pixel values:
- Average canopy height in meters
- 32767 is a null value: the pixel does not belong to forestry land or canopy height is outside boundaries set (0.5m to 50m)
- For the data distributed in windPRO, the null values and missing data are neglected.

Spatial Resolution: 16m

Coverage: This dataset covers 152 of 432 municipalities - however more areas will be added in 2019. See the coverage in the figure to the top-right.

Releases:
- 2019.08: 152 of 432 municipalities are released with windPRO 3.3+
