#793: Provide breakline (fault line) support for surface interpolation modules -------------------------+-------------------------------------------------- Reporter: marisn | Owner: [email protected] Type: enhancement | Status: new Priority: normal | Milestone: 7.0.0 Component: Vector | Version: unspecified Keywords: | Platform: Unspecified Cpu: Unspecified | -------------------------+-------------------------------------------------- Current v.surf.* modules do not support breaklines (fault lines). It's common in geology and other fields to have line/surface that limits interpolated value expansion - interrupts spatial correlation (neighborhood influence).
IMHO breaklines should be taken into account at two times - first when choosing data input points for calculation (only points at one side of line) and second time - when assigning values for cells - only cells at one side of line should receive values. I understand that this is longterm goal and it requires lot of discussions how it should be implemented. Still it's a wanted feature. -- Ticket URL: <http://trac.osgeo.org/grass/ticket/793> GRASS GIS <http://grass.osgeo.org>
