Tree Canopy Cover Loss Yearly per District - Germany, 2018-2021

The product contains information of tree canopy cover loss in Germany per district (Landkreis) between January 2018 and April 2021 at monthly temporal resolution. The information is aggregated at from the 10 m spatial resolution Sentinel-2 and Landsat-based raster product (Tree Canopy Cover Loss Monthly - Landsat-8/Sentinel-2 - Germany, 2018-2021). The method used to derive this product as well as the mapping results are described in detail in Thonfeld et al. (2022). The map depicts areas of natural disturbances (windthrow, fire, droughts, insect infestation) as well as sanitation and salvage logging, and regular forest harvest without explicitly differentiating these drivers. The vector files contain information about tree canopy cover loss area per forest type (deciduous, coniferous, both) and per year (2018, 2019, 2020, January-April 2021, and January 2018-April 2021) in absolute numbers and in percentages. In addition, the vector files contain the district area and the total forest area per district.

Explanation: See the referenced specification.

Pass: Yes

Statement: All Sentinel-2 and Landsat-8 data since 2017 available through the Google Earth Engine (GEE) with less than 80 % cloud cover were used.

Description: Tree Canopy Cover Loss - Germany 2018-2021 - Processing

Processing:

The Sentinel-2 level 2 surface reflectance dataset available from GEE was processed using sen2cor and the Landsat-8 level 2 dataset is composed of surface reflectance data processed using the land surface reflectance code (LaSRC).

Quality Assurance:

With regard to the spatial accuracy, our assessment based on pixel counts revealed an overall accuracy of 92.8%. The sample-based accuracy assessment revealed an overall accuracy of 98% ± 1% and an area estimate of 643,735 ha ± 120,726 ha canopy cover loss. This map is a modified version of the paper, where we removed low-confidence losses, particularly during early 2018 and the 2020/21 winter.
