[postgis-users] Cost weighted distance raster

[Pierre Racine]

Hi Spencer,

Integrating something in the main PostGIS core is hard work. That’s why I started the PostGIS Addons: to quickly gather PLpgSQL-only functions into an easy to install .SQL file. Why I did not integrate those functions in the Addons yet? Lack of time, not much work involving PostGIS since a while, not sure the code is working properly.

Did you get time to test it? If it work fine, I might take time to add it to the Addons before FOSS4G 2017.

Thanks, Pierre. Did all that work stagnate? Have there been efforts to incorporate into the main PostGIS code? Just curious to know what happened. It would be a shame not to provide such useful functionality if there has already been substantial work done.

My alternative at the moment is GRASS, which I've not found to be terribly flexible for incorporating into a larger workflow.
