It’s been a while since I’ve posted and things have been busy. Soccer season has ended, the kids have finished school and I’ve finished up at my client site and moved back to the office. Among the many things I’ve been working on, I’ve started building an open-source GIS stack. It’s not entirely open-source since…

Creating ArcObjects Spatial Reference Objects From PostGIS Spatial Reference Definitions
As discussed in my previous post, I’m trying to beef up the spatial reference support in zigGIS. I am doing this mainly to introduce support for user-defined spatial references. It pretty much boils down to querying the the appropriate SR from the PostGIS spatial_ref_sys table and applying the value of the srtext column to create…
zigGIS and Spatial References, Part 3
This post updates this post and this one. One of our beloved 5 users ;-), James, pointed out recently that zigGIS still has issues with user-defined coordinate systems. Alas, this is true. When we implemented support for on-the-fly “reprojection,” we limited it to the standard EPSG SRIDs supported by both PostGIS and ArcGIS. This was…
Moving Forward On A Couple of Fronts
Well, it’s been a while since I’ve posted anything technical. Work has been a little crazy and I’m not willing to carve into time with the family to keep other stuff moving. As a result a few things have been sitting for a while but I’ve been able to get around to two things. First,…
zigGIS 1.2 Is Out
Congratulations to Paolo for getting zigGIS 1.2 out the door. He’s put a lot of work into fixing problems with selections and renderers and making it a much more usable tool. His post contains a list of features implemented at this version and it’s really a huge step forward. I am focusing on developing catalog…
PostGIS and ArcGIS 9.2
Updating my earlier post: I completed my upgrade to 9.2 yesterday with the installation of the last service pack. The first thing I did was upgrade zigGIS to ensure that there wouldn’t be problems. I have to say that the first thing I noticed was all of the tools ESRI has integrated with VS2005. I…
zigGIS 1.1.0.20768 Now Available!
Paolo moves fast! The new installer is available for download at the zigGIS project home. Bear in mind that zigGIS depends on the ArcObjects .NET libraries. A good post on making sure you’ve got them is available here. The last version had over 200 downloads. Please feel free to post feedback at the project site….
ArcGIS.Next (+)
Steve has blogged about Clint Brown’s talk at the CA/HI/NV/Guam RUG meeting. There’s nothing particularly suprprising but we’re starting to get dates and features tied to version numbers. I am encouraged that 9.3 will be in beta soon. ESRI’s odd-numbered releases are always more stable. The support for PostgreSQL with ArcSDE is not a surprise….
In For a Dime…
…in for a dollar. I’ve been blogging about zigGIS a lot (more than I had planned to, really). So, today, I joined the project. If you go to the site, you’ll see “bill” listed as one of the project owners. That’s me. I had a long IM session with Paolo today and there’s a lot…
zigGIS Update
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.
