This month in AvaFrame - June 2025 edition

Welcome to the June 2025 update:

As announced, we finished our report on ForestFrame 2 Report, please have a look over at zenodo (German only).

We added new tools for the com6RockAvalanche module: generating scarp and resulting DEMs based on polygons.

The deployment of releases to pypi was overhauled. It should run more stable now.

Also very exciting: we started to include code and configuration for MoT-PSA as well as MoT-Voellmy by NGI (see here ). We are looking forward to getting this to run and fully calibrated. But it will take some time….


Project report ForestFrame II

We uploaded the project report for ForestFrame II in our reports section: https://avaframe.org/reports/

This month in AvaFrame - May 2025 edition

Welcome to the May 2025 update:

This month we took part in the INAC 2025 conference, including a talk on “New Normative and Digital Instruments in Avalanche Protection” which also had AvaFrame as a topic.

One of the biggest change this month is the switch away from conda to pixi for our development environment. The documentation has been updated accordingly.

The project ForestFrame 2 is coming to an end, we are currently working on the report. You can expect some changes regarding resistance areas in future releases.


This month in AvaFrame - April 2025 edition

Welcome to the April 2025 update:

This month we released version Version 1.12

We improved documentation based on user feedback regarding com1DFA null variant and naming, and com2AB splitpoints. We added a profile plot example to documentation gallery.

For our Windows users we updated installation instructions.

Added new functionality for remeshing release thickness raster files similar to DEM remeshing.
