I'm new to QGIS and I'm trying to create a statewide map using specific regions, which break down by county. The steps I'm using are:
- Vector Geometry: Fix geometries
- Vector Geometry: Delete holes
- Vector Geoprocessing tools: Dissolve by region
This works, but one county still has an outline on the map, even when the region map is the only layer (though if I check the attribute table, it is combined with its region).
In the attribute table,
Shape_Area are all
0 for only this county, so I'm guessing this may be part of the issue. Is this likely the cause of the problem? And if so, how can I fix it? I got the shapefile from the SOS of the state and I don't have any other source.
