I am having trouble creating a buffer around a polygon of a county in QGIS. When I run the "fixed distance buffer" geoprocessing tool, no features are returned in the 'buffer' shapefile that is created. Has anyone had trouble with this as well? Or does anyone have suggestions of what I may be doing wrong?

Here is the polygon I am attempting to buffer: enter image description here

    Did you try to run the Check Geometry Validity tool? Corrupted geometries may cause this issue.

  • @mgri I just ran that tool and it only returned files with valid geometry, so it looks like there is no invalid geometry to be found within the shapefile.. Commented Feb 21, 2017 at 22:52
  • Did you try with different parameters? Which ones you used, instead?

  • I used the "Check validity" under "vector geometry tools." There weren't any parameter options to select from. I am thinking that the problem may be that the polygon has internal enclaves, but I have been unable to dissolve those into the larger polygon so far. Commented Feb 21, 2017 at 23:12
  • I can't check it now, but I may have a look to your shapefile if you upload it. Is it possible?
