[jira] [Commented] (JENA-10) GeoARQ: a geo location property function for ARQ

["Laurent Pellegrino (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JENA-10?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13036727#comment-13036727 ] 

Laurent Pellegrino commented on JENA-10:
----------------------------------------

I am also interested by this functionality. Geo-spatial data are more and more popular and users need to have the possibility to deal with.

There is a similar but older project which is available here:
http://code.google.com/p/geospatialweb/

> 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).
