Description

In the new API SAGA GIS v2.1 has changed overlapping polygons, now the "Polygons Intersects" function is divided into six separate functions: Intersect, Identify, Difference, Symmetrical Difference, Union and Update.

I attached the path with the new SAGA descriptions of the six features for Sextante, So I think it is not necessary the PolygonIntersection.txt file.

Regards,

Samuel Mesa.

Hi,

After applying this patch for SAGA 2.1 mode, at this time there is no tool that allows to do these operations on SAGA 2.0.8 compatibility mode.

the tools that changed in saga 2.10 need to be "splitted" in processing. Have a look in the tools descriptions file folder and you will see that there are tools (file names) that begin with 210 and also with 208.

Hi Giovanni,

But we don't have any of these on 2.0.8 mode: Intersect, Identify, Difference, Symmetrical Difference, Union and Update. At least in stable QGIS 2.0.1.
