Acquire various raster layers from ODS Europe and crops to an eLTER site boundary.
Source:R/get_site_ODS.R
get_site_ODS.Rd
Download and return a SpatRaster object containing the requested dataset from ODS, cropped to an eLTER site boundary, which is obtained from the DEIMS-SDR API.
Arguments
- deimsid
A
character
. The DEIMS ID of the site from DEIMS-SDR website. DEIMS ID information here.- dataset
A
character
. The requested dataset. One of: "landcover", "clc2018", "osm_buildings", "natura2000", "ndvi_spring", "ndvi_summer", "ndvi_autumn", "ndvi_winter", "ndvi_trend", "forest_broadleaf", "forest_mixed", "forest_coniferous". Default is "landcover".
Value
The function returns a SpatRaster object (from the terra
package)
of the requested dataset, cropped to the site boundaries
The user should save the raster to disk, if necessary.
i.e. writeRaster(ds_site, "site_dataset.tif")
Details
Supported datasets from the ODS repository include: Landcover: Land-cover class according to the highest probability, generated by a spatiotemporal ensemble-ML model. 30 m. resolution CLC2018: Corine land cover rasterized to 100m spatial resolution and provided by Copernicus Land Monitoring Service. OSM buildings: Buildings according to OSM polygons and the Copernicus impervious build-up layer (2018), aggregated and rasterized first to 10m spatial resolution and after downsampled to 30m by spatial average. Natura2000: Protected areas rasterized from NATURA 2000 (A, B and C site categories) and OSM (IUCN Ia, IUCN Ib, IUCN 2, IUCN 3, IUCN 4, IUCN 5, IUCN 6 and others categories), first to 10m spatial resolution and after downsampled to 30m by spatial average. The overlap areas are indicated in a new category. NDVI: NDVI time-series, derived from the Landsat quarterly temporal composites NDVI Trend from 2000 - 2019 as OLS regression Forests: Broadleaf, coniferous or mixed forests All datasets are georeferenced to the EPSG:3035 coordinate reference system. and all except clc2018 have 30 meters resolution
