[GRASS-web] GRASS i.segment

Dear Guy,

[CCing Markus Metz who is the author of i.segment and has a better 
picture of its dependencies.]

Could you explain what exactly you mean by "standalone python package of 
the i.segment" ? i.segment is written in C. Are you looking for someone 
to port the code to a Python  ? Are you looking for python wrapper code 
around the C code ?

i.segment relies on many elements of the GRASS GIS core libraries, so 
porting as such would not be easy because it would mean rewriting large 
parts of the GRASS GIS raster libraries in Python.

No, there is no plan to create standalone apps out of GRASS GIS modules.
There are however efforts to make GRASS GIS modules very easy to call 
even without the normal preparatory steps of creating a location, 
mapset, etc.

Vavlav has been very active providing the grass --exec interface.

However, this still means installing GRASS GIS, at least the core parts 
of it (no needs for the GUI components, for example), or, as mentioned, 
rewriting large parts of GRASS GIS.

There might be developers willing to work on something like, this, but I 
think you will have to clarify your request a bit more.

Maybe a solution with the core, necessary elements of GRASS GIS 
libraries and a python wrapper around the i.segment module would be an 
acceptable solution for you ?


Best wishes,
Moritz
