Understanding of python, some understanding of Dutch and at the end only a little understanding of QGIS required.
The elevation of this point appears to be 667.6 m. The output on the screen looks like:
To read the elevations of a file of coordinates the python code may look like here below.
Thsi si the file: readaltitudes2a.py (not for use! Only to help you write your own program.)
And the output on the screen like this:
A text file is created with outcrop number, SVG-GUI coordinates, Swissgrid coordinates and the elevation
(in meter) as shown below:
We import this text file with the elevations into QGIS prject with the
appropriate georeferenced Swiss topographic map as shown below. In the lower
right corner you can see that the coordinate reference frame (CRS) is EPSG:21781
Now add delimited text layer (symbol with the big comma) and the below pop up
window appear. Select the text file with the coordinates of the outcrops. Space and
comma should be selected as delimeters. As x-field chose field_4, as y-field
chose field_5, as Z field chose the elevations of field_6 and as M field the
outcrop numbers of field_1 and add.
The result may loo like here below. You know yourself how to improve the lay out.
