I have two layers each of which have hundreds of polygons. I want to create a new layer, which is reflective of the features which the two layers don't share.
I've been using the QGIS difference and the symmetrical difference tools, and even though the map displays right, the feature count is totally off.
For example, the first layer has 3,000 features and the second has 1,000. The new layer should have 2,000. And, again, even though it displays just fine with the difference tool, the feature count is like 2999 on the new layer. I don't get what's happening. I need the feature count to be accurate because I need the CSV file.
