I am completely new to Qgis and to gis in general. I have start to work my way through the documentation but have a question that I can not find a answer to. When looking into the documentation related to Data Capturing I find plenty of examples when creating lines and polygons using interactive picking.
If I instead have the data in text file (containing coordinates) how do I import the text file? I have tried to create a layer from "delimited text files" but I do not want to create a new layer I would like to add this data to an existing layer and in addition add attribute data.
How is this done in the best way?
