I have a single polygon shapefile (EPSG: 3044) which I want to enlarge using QGIS 2.18.16. I tried to use the vector affine transformation plugin, but whenever I try to change the size of the polygon, the whole layer changes its position and shape. Is there a tool in QGIS where I can do this task or is it possible with the affine transformation plugin and I just cannot find the right values?
What I have: Some csv points and a country-border. The points do not have the correct positional accuracy. Therefore I want to enlarge the country-border so that all points fit into the poylgon.
