Buffer function

Priority: major Milestone: Support for GeoSPARQL 1.0.1
Component: postgis Version: all

Description (last modified by kkyzir) (diff)

The implementation of the buffer function needs to be modified. We could adopt the definition of the buffer function defined in GeoSPARQL.

geof:buffer (geom: ogc:geomLiteral, radius: xsd:double, 
             units: xsd:anyURI): ogc:geomLiteral

This function returns a geometric object that represents all Points whose distance from geom1 is less than or equal to the radius measured in units. Calculations are in the spatial reference system of geom1.

This ticket should be addressed after ticket #23 is fixed.

The geof:buffer function should be accessible from the SELECT clause of a SPARQL query.
