2D Features
A layer of the type "2D features", delivers 2D geometries. It can contain lines, points or polygons.
Since the 2D geometries are not optimized for WebViewing, the use of "2D Features" is only recommended for relatively small amounts of data.
If you want to publish large quantities of 2D geometries with high performance, please use the “MapProxy” or “PMTiles” layer types.
