How to convert a csv file to shapefile

Imagine you need to have a shapefile made of some points you have around from a sampling.
You want to create a shapefile out of it.

step 1: create a simple CSV file with the coords to add an attribute:

11.33260, 44.16922,test1
11.34121,44.17156,test2



step 2: go under the file menu and select import



step 3: fill in the wizard parameters
  • the csv file to convert
  • the output shapefile
  • the description of the shapefile. The first is the geometry, which can be of 2 coordinates or 3 (need to check the box for that). Then every other attribute needs to have exactly one equivalent in the csv file
  • the coordinate reference system




step 4: press finish and drag the new created shape in the map
