Paolo has posted an update to zigGIS. This update deals more effectively with data layers that have an SRID associated (SRID != -1). They now seem to overlay well. On-the-fly reprojection is still not working but he is working on it. Archaeogeek recently posted about some issues getting zigGIS to work.
zigGIS Installer
Paolo has created an installer for zigGIS and has also posted an installation guide. He has packaged together all of the correct versions of the supporting components so it solves the problems I described in an earlier post. I would highly recommend using the installer to get started.
The FedUC Approaches
The ESRI Federal User Conference is almost here. I’ll be going this year because my company is doing a booth. I like to refer to this event as the “UC-Lite” in that it’s smaller and more focused. I highly encourage anyone in the DC/MD/VA region to go. First of all, admission is free to all…
Happy New Year and a Continued Merry Christmas
Greetings to all and wishes for a peaceful and prosperous 2007. And, for those of you keeping track at home, today would be “seven swans a-swimming”. I’m heading out for a business trip tomorrow that keeps me gone for the rest of the week so it’s time to pack away the decorations. Typically, we wait…
zigGIS and Spatial References, Part 2
Update to this post: Another post about zigGIS. I didn’t really intend this blog to be so dominated by zigGIS but that’s certainly the way it’s been thus far. Basically, it’s just really cool and it satisfies my geek nature on a couple of fronts. After posting about the spatial reference issue before, I couldn’t…
Why Isn’t ArcGIS Explorer Open Source?
I was tinkering with AGX today, mainly trying to get comfortable with the API. As I was playing with it, this thought crept into my head: Why isn’t this thing open source? Okay, aside from the fact that it was released by ESRI… There are two main reasons that I ponder this: First, it’s already…
zigGIS on Google Code
It seems this is quickly turning into the zigGIS blog. Anyway, it appears that Paolo Corti has assumed the role of project lead on zigGIS and has moved it to Google Code. I’m excited because I think this is a great project and this should keep it moving forward. There’s also a group for discussing…
zigGIS and Spatial References
I’m still playing around with zigGIS and I have noticed that it doesn’t seem to play well when I define the spatial reference of a data set in PostGIS. Any data set that has a defined spatial reference fails to draw in ArcMap. In addition, the layer properties always indicate that the coordinate system is…
PostGIS and ArcGIS 9.1
I’ve been intrigued for some time by an open-source (GPL) project out there called zigGIS. It is a C# project that enables a direct read of PostGIS by ArcGIS. It is intriguing for a couple of reasons. First is the promise of reading directly from PostGIS and working with your data in ArcMap without the…
Good Article on Optimizing Open-Source Software
There’s been a lot of recent buzz about open-source GIS software. Good discussions can be found at James Fee’s site, plus Datum Shift as well as on Dave Bouwman’s blog. Given all of this discussion, I found this article in Dr. Dobb’s Journal to be rather timely. It’s not about GIS software per se but…
