Hi, At present the union tool does not give correct results in sextante/ftools. After looking at some bug reports, I feel that even in QGIS 1.8, the union tool was not producing the correct output either attribute-wise or geometry-wise.
My question is how should the real output be? I have two cases here. 1. Union of a single layer against itself - https://www.dropbox.com/sh/asicnvr71vxeaz2/TKVUpdleIX#f:singleLayerInput.png 2. Union between two different layers - https://www.dropbox.com/sh/asicnvr71vxeaz2/TKVUpdleIX?lst#f:twoLayerInput.png It looks to me that for case 1, the result could be like below(11 geometries in total) https://www.dropbox.com/sh/asicnvr71vxeaz2/TKVUpdleIX?lst#f:singleLayerResult1.png and for case 2, the result could be like below https://www.dropbox.com/sh/asicnvr71vxeaz2/TKVUpdleIX?lst#f:twoLayerResult1.png what do you think? Anybody knows how it looked in 1.8?
