Christmas zig

I have some exciting news for you zigGIS users - editing functionality has finally received some love! Click on to view a screencast of the newest zigGIS capabilities. But, before I go any further, allow me to alert you of some licensing changes:

Bill Dollins, Paolo Corti, and I have all worked extremely hard molding zigGIS into what it is today. We want to continue to develop and support our product. Therefore we have decided that our next release will require purchased licenses for our corporate users. OK, OK, before you go trashing us, please take a minute to read on and understand our position.

First and foremost, the zigGIS codebase will remain open. Secondly, personal and educational use of zigGIS will remain free. We hope many more become interested in zigGIS not only for its use, but also utilizing it as an example of deep ArcMap customization and use of the ArcObject API. We have gone through hundreds (maybe thousands) of trial-and-error hours wrestling with ArcObjects. By keeping the codebase open, others can learn from our mistakes and avoid the pitfalls to which we have oft found ourselves prey.

As for our corporate users - you will need to purchase licenses per seat. Licenses will fall somewhere below $300 each. We hope this keeps zigGIS affordable to those organizations that require heavy-duty GIS capabilities. (don't forget that the use of PostGIS + zigGIS saves you from all ArcSDE licensing costs) Bill, Paolo, and I are forming a software company around this product. And - though certainly we want to make a profit - this will ultimately best serve our users' interest. Having a financial backing will ensure zigGIS's continued support and development.

Thank you for your interest, patience, and support. Stay tuned for more news and have a safe and happy holiday!

Great work. Sorry if some of my comments and/or questions are ignorant.
Why can't the editing be handled through the Editor toolbar directly into PostGIS? Are they technical reasons or reasons of logical flow of database manipulation?
Does the tmp layer showing up in the TOC mean that their is actually a temporary copy of the data stored on hard disk (sans pg_arc)?

@bobintn - we spent countless hours doing detective work trying to shake out exactly what ArcMap required of our code to allow direct editing. We never found joy. Yes, our approach is somewhat akin to pg_arc, but differs in all the ways that matter. And actually, believe it or not, has some benefits over direct PostGIS-Editor integration. However, that discussion requires a greater commitment and a post about such technical details is to come. For now, allow me to say that ultimately that end-user experience will be completely - in a word (of which I fumbled for in the screencast) - seamless.

We are a non-profit organization fighting malaria in Africa. In my GIS lab I have established postgres and postgis databases for capturing all malaria related data. I was planing to use ZIgGIS for the connection between my ArcGIS and postGIS. I know this might sound cheesy but we have a severe lack of funds. Would I be able to acquire a free zigGIZ license for my work?

@cmonsta - we're not *quite* ready to have this conversation. I'll be in touch.
