Hi Alex,
More than ten years ago, two features were added to GDAL during GSoC
projects: the raster correlator [0] and support for the Geographic
Network Model (GNM) [1]. Both features seem to have remained
limited/experimental, with almost no activity except for code
formatting and compilation fixes.
True
As far as I know, they also are
rarely included in default builds by major distributions/packages,
Are you sure about that ? The raster correlator is part of the build and
cannot be disabled easily, and even if GNM can be disabled, it is on by
default. Debian or conda-forge builds include it for example
the correlator API is not exposed via SWIG.
True
I wonder what is the status and future of this code? Are there any
plans to improve and expose it, or is the project leaning toward
deprecation and removal to reduce maintenance overhead?
I was also wondering lately. We also don't see bug reports or questions
related to them, so they might be little used.
And the fact that gnmanalyze & gnmmanage haven't been ported to the new
CLI will not help build awareness around them.
Those features don't get that much in our way so there's no immediate
need to consider deprecation
In the past I developed an experimental QGIS plugin that uses GDAL GNM
via Python bindings and considered exposing the correlator as well.
In the same plugin ?
I would love to hear your thoughts on the future of these two features
before investing further into plugins, and potentially to the GDAL.
It might be a chicken & egg problem: not enough exposed ==> not enough
used ==> no feedback ==> no change.
But what's true is that the original developers are apparently no longer
available (I pinged recently for a GNM related pull request and got no
feedback).
