Hi, Recently someone asked a question on StackOverflow, if Neo4j Spatial was capable of one of the Oracle geoprocessing funtions, SDO_LRS.LOCATE_PT specifically. Since this is related to the ongoing GSoC projects for Neo4j Spatial, I thought I would do a quick investigation. What I found was that the requested capabilities are available in JTS (which we include in Neo4j Spatial), but with very different names. The code to achieve this in JTS is 'new LengthIndexedLine(geometry).extractPoint(measure,offset)'. I have wrapped these in the SpatialTopologyUtils.locatePoint(geometry,measure,offset), so that it is accessible together with some other spatial topology functions, and also looks more like the Oracle function.
I pushed this to github, and think it can be included as a prototype for the discussions for the GSoC on Geoprocessing. Regards, Craig _______________________________________________ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
