Set to "Local or none" for maps with no labels.
If choosing Ad-hoc search, first choose either WGS84/WebM, or raster tiles (or both).
Style selection is for raster tiles only at present. You need to choose a point/poly style according to the chosen binning.
Note: If none are selected then no filter is applied, which is equivalent to selecting them all.
This is in line with all GBIF search APIs.
