[Qgis-user] digitizing locations (Vol 226, Issue 2)

[Garth Fletcher]

The shapefile you created from your .csv contains only Attributes, NO 
Geometry.
I don't know of a way to easily add geometries, e.g., coordinates.

You could have as easily used Layer > Data Source Manager > Delimited Text
to read in the .csv into an attributes-only layer.  Lets name it "ATTRIB".

A way I would approach it is to create a new point shapefile with an 
attribute which will match an attribute in your .csv or ATTRIB layer.

You are looking in your .csv  or ATTRIB for a field whose values are 
unique to each record.
If the unique field is too verbose, or doesn't exist, then you could add 
a new field to the attributes-only layer in which you place a unique number.

Then create your point shapefile, adding the same type of field, maybe 
naming it "KEY".

As you digitize each location, set its "KEY" value to the same value as 
you have in the .csv
(which is why I recommend using a simple number rather than having to 
type in a long name)

When done, double-click on your new points layer, in its Layer 
Properties dialog scroll down to Joins
to create (+) a new Join.  Specify the attributes-only layer as the 
"Join layer", the name of its matching column
in "Join Field", and the name of the "Target Field" (which would be 
'KEY') in your points layer.

Your points layer, in addition to the location geometry, will  now also 
include all the attributes from your attributes-only layer.
