I am working on a street network in QGIS. I needed to increase the resolution of the street segmentation in an area of my network, so I copied and paste this area from another layer.
The street segmentation is now fine (I got the resolution I wanted in the area I was interested to). The problem is that in the resulting layer, in the areas where the network I pasted overlaps with my original one, I completely lost all of the data in the attribute table.
As you can see, I selected a random street segment in the overlapping area and the corresponding columns in the attribute table are all NULL.
Do you know a way to export this data into the attribute table? Since the street segments that now lack information in the attribute table are quite a lot, it would be great if the method was automatic.
