The CityJson format supports the GeographicalExtent meta information, which allows filtering fast if a file is within a given region of interest or not. This feature could be also added to .geoobj and .geoply.
Proposed .geoobj and .geoply extension with the line prefix e followed by 6 values (first 3 min extent, remaining 3 max extent):
...
e 0 0 0 10 10 10
...
geoply
...
extent 0 0 0 10 10 10
