description: This dataset provides additional information on environmental attributes (minimum distance to land cover classes, topographic information) based on the dataset "BETA-FOR_SPZ_Patches_2022/2023" (https://zenodo.org/records/14748236) (centroid coordinates: decimalLongitude, decimalLatitude).

 

From the following three geospatial datasets the information on environmental attributes were derived:

 

- DLM250 = Digital Landscape Model for Germany (Vector data, https://gdz.bkg.bund.de/index.php/default/open-data/digitales-landschaftsmodell-1-250-000-ebenen-dlm250-ebenen.html)

- ESA Worldcover = Global product on land cover (Raster data, https://developers.google.com/earth-engine/datasets/catalog/ESA_WorldCover_v100?hl=en)

- SRTM = Global Digital Elevation Model (Raster data, https://developers.google.com/earth-engine/datasets/catalog/USGS_SRTMGL1_003?hl=en)

 

The following attributes were added to the "BETA-FOR_SPZ_Patches_2022/2023" table and exported as .csv file (tabular data):

 

DLM250:

- min_dist_sie01_p = minimum distance to urban areas [m]

- min_dist_ver01_l = minimum distance to technical infrastructure (roads) [m]

- min_dist_veg01_f = minimum distance to agricultural areas [m]

- min_dist_gew01_l = minimum distance to waterbodies [m]

 

Please consider that the DLM250 is spatially discontinuous vector data where e.g. agricultural areas are incompletely assessed.

 

ESA WorldCover (ESAWC):

- min_dist_esawc_30 = minimum distance to grasslands (land cover class value = 30) [m]

- min_dist_esawc_40 = minimum distance to cropland (land cover class value = 40) [m] 

 

SRTM:

- SRTM_elevation = elevation [m]

- SRTM_slope = slope [°] 

- SRTM_aspect = aspect; 90° = E, 180° = S; 270 ° = W; 360°/0° = N [°]

 

The original vector and raster data can be made available upon request, e.g. to inspect benefits and limitations of DLM250 and ESA WorldCover.
