Module kml_bridge 

KML import/export bridge.

KML <Placemark> → NQuin stream using GeoSPARQL predicates (internal storage) and PROV-O temporal quins for <TimeStamp> / <TimeSpan>.

Named graph context IDs: SPATIAL_CONTEXT — geometry quins (geo:hasGeometry, geo:asWKT) T_CONTEXT — temporal quins (prov:generatedAtTime, prov:startedAtTime, prov:endedAtTime)

encode_geohash_64

Encode (lon, lat) into a 64-bit interleaved GeoHash integer. Uses 32 bits each for latitude and longitude mapped to [0, 2^32).
