  Here is a list of GeoSPARQL functions that are implemented on KiWi:
  
  || FUNCTION || TYPE || DESCRIPTION  || STATE || SYNTAX ||
- || INTERSECTS || Boolean || Returns geometries (arg_A) intersecting with 
other geometry (arg_B) || Implemented || geof:sfIntersects(?arg_A, ?argB) ||
+ || INTERSECTS || Boolean || Returns TRUE if arg_A intersect with arg_B 
geometry || Implemented || geof:sfIntersects(?arg_A, ?argB) ||
- || WITHIN || Boolean ||  Returns  geometries arg_A that are completely inside 
geometry arg_B || Implemented || geof:sfWithin(?arg_A, ?argB) ||
+ || WITHIN || Boolean ||  Returns TRUE if the geometry arg_A is completely 
inside geometry arg_B || Implemented || geof:sfWithin(?arg_A, ?argB) ||
- || CONTAINS || Boolean || Returns true if and only if no points of arg_B lie 
in the exterior of arg_A, and at least one point of the interior of arg_B lies 
in the interior of arg_A. || Implemented || geof:sfContains(?arg_A, ?argB) ||
+ || CONTAINS || Boolean || Returns TRUE if and only if no points of arg_B lie 
in the exterior of arg_A, and at least one point of the interior of arg_B lies 
in the interior of arg_A. || Implemented || geof:sfContains(?arg_A, ?argB) ||
  || OVERLAPS || Boolean || Returns TRUE if the Geometries share space, are of 
the same dimension, but are not completely contained by each other. || 
Implemented || geof:sfOverlaps(?arg_A, ?argB) ||
  || TOUCHES || Boolean || Returns TRUE if the geometries have at least one 
point in common, but their interiors do not intersect. || Implemented || 
geof:sfTouches(?arg_A, ?argB) ||
- || EQUALS || Boolean || Returns true if the given geometries represent the 
same geometry || Implemented || geof:sfEquals(?arg_A, ?argB) ||
+ || EQUALS || Boolean || Returns TRUE if the given geometries represent the 
same geometry || Implemented || geof:sfEquals(?arg_A, ?argB) ||
+ || DISJOINT|| Boolean || Returns TRUE if the Geometries do not "spatially 
intersect" - if they do not share any space together. || Implemented || 
geof:sfDisjoint(?arg_A, ?argB) ||
+ || CROSSES || Boolean || Returns TRUE if the supplied geometries have some, 
but not all, interior points in common. || Implemented || 
geof:sfCrosses(?arg_A, ?argB) ||
+ || INTERSECTION || Geometry|| Returns a geometry that represents the shared 
portion of arg_A and arg_B. || Implemented || geof:intersection(?arg_A, ?argB) 
||
+ || CONVEXHULL|| Geometry|| The convex hull of a geometry represents the 
minimum convex geometry that encloses all geometries within the set. || 
Implemented || geof:convexHull(?arg_A) ||
+ || BUFFER || Geometry|| Returns a geometry that represents all points whose 
distance from this Geometry is less than or equal to distance. || Implemented 
|| geof:buffer(?arg_A, radius) ||
