> GeoARQ: a geo location property function for ARQ
> ------------------------------------------------
>
> Key: JENA-10
> URL: https://issues.apache.org/jira/browse/JENA-10
> Project: Jena
> Issue Type: New Feature
> Components: ARQ
> Reporter: Paolo Castagna
> Priority: Minor
>
> Similarly to LARQ, we can use Lucene spatial capabilities to provide a
> geo/spatial property function for ARQ.
> An initial and experimental implementation as proof of concept is available
> here: https://github.com/castagna/GeoARQ
> The initial implementation can provide:
> - ?s geoarq:nearby ( lat long ) // lat and long are in WGS 84, results are
> sorted by some "unspecified" score
> - ?s geoarq:nearby ( lat long dist ) // restrict withing dist km from
> (lat,long)
> - (?s ?d) geoarq:nearby ( lat long ) // results are sorted by distance (?d)
> which is made available to the user
> - (?s ?d) geoarq:nearby ( lat long dist )
> - ?s geoarq:within ( lat1, long1, lat2, long2 )
> GeoARQ would be better as a separate module from ARQ (same as LARQ).
