Land Cover

Is your feature request related to a problem? Please describe

The land cover layer on the explore site currently has artifacts around the edges of the features. The underlying geoparquet is overlapping as well.

Describe the solution you'd like

Prior to the release of the land cover layer, the geometries are trimmed to guarantee no overlaps.
