overlapping, QGIS can be used to remove some labels. However, selecting the option to "Show all labels for this layer (including colliding labels)" overrides this setting, which creates the undesired situation.
If I have two overlapping polygons and I want to remove the overlapping area, theresulting geometry is invalid. I've noticed this using EPSG:3061. It is always failing (for a few tests). I've tried to reproduce the error with EPSG:3763 and I was not able to get the invalid geometrie...
QGIS doesn't seem to handle vectors with overlapping features properly and throws out some random errors when editing them. Feature 4 and 10 in your shapefile contains some overlapping. Could you remove those features and try again? Also, worth trying in QGIS master. 9060 was configured as ove...
Now the scaled polygons will have much better placement. We see another problem. Many features in the layer areMultipolygons, i.e. they have more than one part. Such features have 2 or more polygons that are part of the same geometry. With our current expression, both are scaled with ...
Remove the intersection output from QGIS and data folder. Search for Fix geometries tool in the processing toolbox. Double-click to open. Select Zoning as Input layer. Keep all the other inputs as default and save the output layer as zoning_fixed.shp in the data folder by clicking Save to...
Cartograms make it easy to see large variations in the data. The simplest method to create a cartogram is by scaling the size of each region according to a variable. This method retains the original shape of the polygon and only changes the size. These are known as Non-contiguous ...
