Description

Builds further on https://github.com/Open-EO/openeo-geotrellis-extensions/issues/330

This 30min process graph has some stages that could be better partitioned: j-2501031abdb847068383f2563236ee2a Jeroen Dries found that adding a spatial partitioner here would probably enhance it: https://github.com/Open-EO/openeo-geotrellis-extensions/blob/88b8ef663958776861b2387f31caf32cbd703514/openeo-geotrellis/src/main/scala/org/openeo/geotrellis/geotiff/package.scala#L439

Contributor guide
