We have mapped land cover classes for the 2000-2019 period for
continental Europe at 30-m resolution using spatiotemporal Machine
Learning (we used R and python for modeling). Explore the dynamic EU
landscapes on your palm using the ODS-Europe viewer:
https://maps.opendatascience.eu
To access almost 10TB of data using R you use the terra or similar
packages e.g.:
R> library(terra)
R> in.tif =
"/vsicurl/http://s3.eu-central-1.wasabisys.com/eumap/lcv/lcv_landcover.hcl_lucas.corine.rf_p_30m_0..0cm_2019_eumap_epsg3035_v0.1.tif"
R> tif = rast(in.tif)
From here you can use any native operation e.g. to crop some polygon
or resample / aggregate values (there is no need to download whole
data sets). A detailed tutorial on how to work with Cloud Optimized
GeoTiffs is available here:
https://gitlab.com/openlandmap/global-layers/-/blob/master/tutorial/OpenLandMap_COG_tutorial.md.
Complete list of Cloud Optimized GeoTiffs we produced so far for Europe
is available here:
