HOME ยป PHP

I'm looking for a very basic example of using neo4j spatial features from php, preferably with the use of this library neo4jphp


i want to store a list of venues with their latitude and longitude


how do i store such information? can the lat and long be stored with the other venue info in one node?


how do you find venues around some given point?


thanks


edit: with spatial features i mean the spatial plugin for neo4j

Neo4j Spatial Converting wkt values to something else
18/1/2015 9:10 pm PHP

My application uses point queries to find stores based on a user's current location.

public class Store extends AbstractNode {

    @Indexed(indexType = IndexType.POINT, indexName =
"ErrandLocation") 
    private String wkt;

   public void setLocation(float lat, float lon) {
      this.wkt = String.format("POINT( %.2f %.2f )",lat,lon);
   }
}

On saving a shop with shop.setLocation (12, 12); and I use the neo4j browser to inspect my nodes, the wkt value changes to POINT( 56.34 -2.80 ).

I do not understand why the value changes to this from POINT (12.00, 12.00).


is Neo4J-spatial already included in heroku?
PHP

I have been reading about Neo4J: https://github.com/neo4j/spatial/blob/master/src/test/java/org/neo4j/gis/spatial/TestSimplePointLayer.java


but I cant' understand how to use them, in fact I don't even know if this is supported in the beta version of Neo4J in heroku, could someone tell me if this is possible and if so, do you have some code that can guide me on how to add Latitude/Longitude to a node? In REST API if you can, because I'm using .Net so I can't have the complete client library in java


thanks in advance


neo4j spatial wgs84 distance

I'm using this code to find nearest nabours to an given point in the wgs84 format(the variable co)for(Node n : geomPoints){ ExecutionResult result = engine.execute("START a=node(" + n.getId() + ") "+ "MATCH a-[:FIRST_NODE]->()-[:NEXT*0..]->()-[:NODE]->b "+ "RETURN b"); Iterator<Node> nodes = result.columnAs("b"); while(nodes.hasNext()){ Node nodesInGeom =
