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.

This month in AvaFrame - March 2025 edition

Welcome to the March update:

Apart from the usual bug fixes and improvements, we changed one pain-point by adding mid-run persistence (e.g., saving progress/simDF) and resume capability for multi-simulation runs of com1DFA. This allows for restarts of simulations

Regarding shapefile polygons produced by AvaFrame: these are properly closed (endpoint equals startpoint) now, both for idealized release areas and when writing shp files

On the admin side, we replaced Code Climate and Codecov with qlty.sh, which is relevant for developers only.

This month in AvaFrame - February 2025 edition

Welcome to the February update:

As you might have noticed, we released two new versions this month:

-Version 1.10

-Version 1.11

So one includes the new geotiff capabilities, while the other one is a maintenance release to update the benchmarks.

So to emphasize this: due to the changes in the IO routines, the benchmarks have changed slightly! This is mostly visible in areas on the border of the flow or really strong gradients. However, the differences are well within acceptable ranges. But don’t take it from us, please see the attached report for the differences (version 1.11).

Release Version 1.11

We released Version 1.11

QGis users please note (after updating the plugin): do not forget to run Admin -> Update AvaFrame from within the toolbox to receive the updated core as well.

As mentioned in the previous release, there are some changes in the benchmarks, which are now updated:

This is a maintenance/benchmark release. We updated ALL benchmarks due to the IO changes in version 1.10. The report with the differences in v1.10 is attached as pdf.

This month in AvaFrame - January 2025 edition

Welcome to the first update of 2025:

Major work is being done of a change on our input side: we are including support for geotiff files. We will of course keep the asc format, but the geotiff format allows for a better integration and checks in relation to geographic information (i.e. coordinates, projections, etc.). Expect this to be released with a new version within the next weeks.

Work on the ISeeSnow paper is progressing nicely, as well as the work on our regional modelling project.

Release Version 1.10

We released Version 1.10

QGis users please note (after updating the plugin): do not forget to run Admin -> Update AvaFrame from within the toolbox to receive the updated core as well.

The path generation and geotiff release. So the main changes are:

  • The raster reading routines now accept geotiff files as well
  • we updated the automatic path generation, this will also end up in the QGis connector
  • added a new spatialVoellmy friction setup, to read mu/xi values from raster during initialization.
  • fix a long/long Windows bug (again…)
  • some plot can include a (online) background map

Please be aware: the module ascUtils is being deprecated. Please use rasterUtils which has the same functions in it. ascUtils will be removed in a future version.

This month in AvaFrame - December 2024 edition

Welcome to the December 2024 update:

Related to ForrestFrame 2 we are looking into different treatment of resistance forces, experimenting with existing approaches and ideas. A lot of work is going into the report of the ISeeSnow project, which we aim to publish next year.

And this is basically a repeat from last month: the regional modelling project is also coming along nicely.
Current topics are the splitting of larger input areas and efficient handling during computation.
