[Neo4j] Re: Searching for spatial nodes into geometry box from shapefile

2014-08-20 Thread Jim Biard
Arnaud, If you are using the Neo4j Spatial plugin, geometries will be computed from the shapes if you use the shape file importer. They will be in the Well-Known Binary (WKB) format, but they will be present. Are you looking for something more or different than this? Grace and peace, Jim On

[Neo4j] What constrains the possible inputs to a legacy index provided by an extension in Cypher?

2014-08-20 Thread Jim Biard
Hi. I am working with Neo4j Spatial, and have found that when constructing queries in Cypher alone (no parameters) I appear to be unable to pass anything but a string literal as an argument to a spatial index query. As best as I can sort out so far, this isn't a constraint imposed by the plugi

[Neo4j] Re: Relationship between SpatialDatabaseRecord nodes

2014-07-26 Thread Jim Biard
Alireza, The SpatialDatabaseRecord class holds a reference to the node you created when you made the runningLayer.add() call. This node reference is returned when you call getGeomNode(). (I assume that the runningLayer is holding WKT or WKB geometries - otherwise adding these different geometry

[Neo4j] Re: How many indexes for spatial data?

2014-07-18 Thread Jim Biard
Alireza, These questions are so broad that it's hard to answer. If you want to be able to get all of your different nodes back from a single query, then they must all be in the same RTree layer (accessed through a spatial index in Cypher). If different kinds or subsets of spatial nodes are to
