[GRASS-dev] Submitting module to addons - r.sundenoise - mentor required

GRASS GRASS developer
1

Hi,

I have written an add-on module. It is called r.sundenoise and it is for denoising/despeckling DEMs to improve the quality of slope maps and other geomorphic products derived from them. The denoising is carried out by Sun's denoising algorithm, a GPL'd mesh filtering algorithm that I have been testing on topographic data as part of a research project. It does a very nice job.

My module is a shell script that works as a wrapper to the algorithm so that it can be run from within GRASS, in much the same way as r.surf.nnbathy works as a wrapper for nn. I would like to submit it to the add-ons repository.

I have read and will abide by the document RFC2 - Legal aspects of code contributions. I have an osgeo_id: stevensj

Would someone like to be my mentor? You can try the module at:

Cheers

Hi,

My module is a shell script that works as a wrapper to the algorithm so that
it can be run from within GRASS, in much the same way as r.surf.nnbathy

too much work to rewrite it to Python? (If I can suggest please write
new modules in Python). In GRASS7 there is no extra support for shell
scripts.

Hi Martin,

I have in my mind to write a python version at some stage, as it isn't a complicated script. But first I need to learn python...

I uploaded a shell script first as I have had a paper accepted about the denoising algorithm and I want to mention in the paper that it can be run via a GRASS module. I need to send the revised draft back to the editor next week, so I wanted to have a working version online as soon as possible. Once a working version is up and available I can have a look at making a python version.

Cheers

John
