I have a problem with vector data tools/ merge vector layers using QGIS 2.18.0.
This is the procedure that I took:
And now I want to merge these two layers into the layer the already exists and is the first one that I created (that one with smaller separate polygons). My problem is, that after using the function merge vector layers, the result is same as it is in the original photo. The borders between the polygns are still there.
I don't know where I am making the error.
Is there any other option to delete the borders of the polygons, without having to save into a separate shapefile?
