I have a csv file with information but not georeferenced. I'd like to load it in QGIS and add points (with coordinates) in the same file and later save as a shapefile. Is there any way to doing that or just creating an independent layer with the points and then joining both layers? If that is the case should I have a common ID to do that. I do not have one. Does the number ID could work on that?
It's probably easiest to create IDs using a Spreadsheet software. Then create points with those IDs in QGIS and join the files later.
Another approach would be to add fake coordinates to the csv and then move them to the correct position.
