At the moment I do this manually:
- open a shapefile
- open the attribute table
- use "select features using an expression" - the expression is "area" < 200
- then I use vector/geoprocessing tools/eliminate sliver polygons
- I select "common boundary", add a name and location for a new shapefile.
I have tried to automate this process using the modeller, but even after looking at some tutorials I could not achieve this.
Since I have many shapefiles, I would like to process them one at the time automatically. Note that the resulting shapefile should have the original shapefile name with a prefix or a suffix - I don't mind which.
After spending some time with QGIS, I had a look at the "Processing Toolbox" and I have tried "Eliminate Sliver Polygon" as a Batch Process. It seems like it should do what I am looking for - but I guess that my parameters are not correct and reading the help file did not help me. There are three entries that I have to fill in:
- Selection Attribute
In "selection attribute" I have tried "AREA" (with and without quotes), but is this the correct parameter?
