Julian et al., -- is there a project/Github wiki, or something similar where I could write up a plan for implementation of OpenGIS functions, their mappings to ESRI library, and have this open for review?
Or should I just open up a new Google Doc. for this? Edmon On Wed, Nov 1, 2017 at 5:50 PM, Edmon Begoli <[email protected]> wrote: > Julian, thanks. Sounds like a plan.
