Alfredas, I am not too familiar with the natural resources industry, but for the meeting points and approximation of them, you could probably use something like the snapping support that is provided in Neo4j Spatial (right now for snapping points to line segments, see https://github.com/neo4j/neo4j-spatial/blob/master/src/test/java/org/neo4j/gis/spatial/TestSpatialUtils.java#L135 )
Would that be of interest?
