A new version (5.0.1) of pygsf adds tools for the creation and analysis of parallel profiles, for instance directly into a Jupyter notebook.
What is pygsf? It's a Python module devoted to the processing of topographic and geological data.
With the new tools, multiple profiles can be plotted, as well as their statistical properties: for instance the range of the profiles, their minimum, maximum and mean traces. The profiles can also be exported as a line shapefile, in order to visualize them in a GIS software (e.g. QGIS), or exported as an animated gif.
The images below represent a brief tour of the methods available.
First is a simple plot of a single topographic profile.
We can create multiple parallel profiles, for instance 5 parallel profiles produced from the base profile using a user-provided normal offset:
The multiple profiles can be plotted into a single graph:
They can be composed into an animation (quite slow to play, I admit):
The minimum and the maximum of the profiles along the trace can be plotted in a single profile:
and also the range (maximum - minimum) calculated and plotted:
Last showed method is the possibility to save the multiple profiles into a new line shapefile, that can be loaded for instance in QGIS to display the locations of the topographic sections created (the Mt. Alpi zone in the Lucania Southern Apennines, Italy):
