Landcover dataset to graph #8

Closed sdat2 closed 3 years ago

herbiebradley commented 3 years ago
  1. Only landcover dataset on CEDA - 300m resolution
  2. Copernicus global landcover dataset - 100m resolution, available GEE
  3. Copernicus European landcover dataset - 20m resolution, direct download.
  4. UK landcover dataset - 20m resolution, need to request access to data

All datasets appear to use GeoTiff format, so recommend we start with 1. since it's on CEDA. Then we can write some preliminary code to make a graph from the data for the Cambridge area as a first test, before scaling up or moving to one of the other datasets. Consider using pylandstats as a convenient way to process GeoTiff data.

Note: pylandstats does not lazily load large .tif files, so we may want to use rasterio for the full project.
