Qgis Connector
Webinar
Welcome to our monthly update for November.
Feeback
working MacOs
There are some changes especially for those wanting to try and test AvaFrame:
Some problem related to QGis
- the AvaFrame QGis Connector is now out of the experimental state, so it is easily installable via the QGis plugins
manager. No more need to enable experimental plugins. See
[QGis plugin directory](https://plugins.qgis.org/plugins/avaframeConnector/).
- We had our first webinar with about 15 test users. This group is testing AvaFrame from an operational point of view.
The first feedback is already rolling in, and we already discovered some more snags. However, so far nothing too serious.
Some, as yet to be solved, problems concern file access rights on windows machines. If you hit a similar problem, we'd
be happy to hear from you! (e.g. via a github bug report...)
We're back from summer! And with some exciting news too!
- For those working on MacOS: there are successful installations on current MacOS versions. The safest way seems to be
to install QGis via conda (anaconda; conda-forge).
[Version 0.6](https://github.com/avaframe/AvaFrame/releases/tag/v0.6),
the **QGis/pypi and testing** - release, was published.
- We are investing more effort into the improvement of our testing. Both unit testing and model testing are tackled.
This is applied right away for current developments like the ongoing investigation into initial particle distribution
methods.
So what is included in this release?
- Work is also being done on the similarity solution test, comparing DFA results to an analytic solution.
- The installation process was completely changed and (hopefully) made a lot easier for you:
- installation of AvaFrame is now working via [pypi](https://pypi.org/project/avaframe/),
i.e. through *pip install avaframe*.
- the *pip* install is provided for Windows, Linux and MacOS for python versions *> 3.6*. Note that
we did not test MacOS (anyone got a free Macbook lying around?! :-); seriously: if you work on MacOS
we'd be happy about some feedback!)
- the QGis connector plugin is now in the public
[QGis plugin directory](https://plugins.qgis.org/plugins/avaframeConnector/)
and installable via the QGis plugin manager. This allows you to run the standard operational
workflow from within QGis.
- see our [installation instructions](https://docs.avaframe.org/en/latest/installation.html) for more information
- As mentioned last month, a, what we call *hybrid model* is being developed. This includes automatic path finding
from a combination of DFA simulations (com1DFA) and alpha beta results (com2AB). Expect the full module hitting our
code base soon.
- Our testing / code coverage has improved considerably. We are still long ways away from perfect, but this is an
ongoing process. As a side-note: we switched from codecoverage to codeclimate as service provider, since we felt we
gain more insights this way.
- Modules with the most substantial changes are:
- *com1DFA*:
- any resolution is possible (also see the new [FAQ](https://docs.avaframe.org/en/latest/FAQ.html))
- option to track particles by ID and know which parent particle they originate from.
- include entrainment thickness from shapefiles
- new option for the initialisation of particle mass
- *ana3AIMEC*: adjust raster cellsize (for different resolutions) and mass analysis plots
- The documentation now includes information about an extended method to split and/or merge particles during computation
of the com1DFA module. See [here](https://docs.avaframe.org/en/latest/DFAnumerics.html?highlight=merge#particle-splitting-and-merging)
for more information.
- And as always: many more functional changes under the hood, see the main ones in our
[release notes](https://docs.avaframe.org/en/latest/releaseNotes.html).
We invite you to give this version a try, especially the *standard installation using QGis*. Please let us know
if you run into problems (which you will...). We are looking forward to your feedback!
We plan on offering a **public webinar** for everyone interested. It is currently set for the beginning of February,
watch this space for an announcement soon!
And since I can see fresh snow up on the mountains from where I'm writing this: let the next avalanche season begin...
Till next month,
That's it for this month, happy skiing, snowboarding or whatever satisfies your winter-y needs!
