CountTags returns the different tags in the database and the number of instances of each one.

DominantType returns the most frequently occurring type among the given features.

ExtractFile extracts OpenStreetMap data from the given file path, determining whether it is an XML or PBF file from the extension (.osm or .pbf, respectively).

ExtractPBF extracts OpenStreetMap data from osm.pbf file rs.

ExtractTag extracts OpenStreetMap data with the given tag set to one of the given values.

ExtractXML extracts OpenStreetMap data from osm file rs.

KeepAll specifies that all objects should be kept.
