[postgis-users] Cost weighted distance raster

[Pierre Racine]

There is no .sql. just copy the functions into a .sql text file and execute.

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.

That makes sense. I don't see a master .sql file to use for adding the functions to the database. The GSOC proposal I linked to previously has code for the Euclidean Distance function, but not for the Cost-Weighted Distance function. Is there a single .sql file somewhere that I can use to create both functions? I'd love to take a look and see if I can get them both working.
