Hi,</p>
<p>I think, your data topologically is not perfect. Use the GRASS Tools to check your data. </p>

Hi,<div>I have problem with geoprocessing tools. I use shp polygon data with projection ESRI:102067. When I try to apply geoprocessing tools on it, there are several errors depending on the tool. Buffer tool is OK.</div><div>
<br></div><div>When try difference or intersection (concretely layers buf_kom, chodniky) two things happened. Sometimes there is bad result (the result layer is the same like the input layer buf_kom, or the result is empty layer). The second thing is attached error.</div>
