The final schedule for that one can be found here. For those on the West Coast, there is PgDay at LinuxFest Northwest in…
Using PostgreSQL Views in zigGIS 2.0.2
When we mapped out the way ahead for zigGIS, we knew we wanted to lay the groundwork to add support for SQL Server 2008 and possibly other database platforms. The way zigGIS was originally constructed, it used the PostGIS geometry_columns table to discover available spatial tables. This has worked well but we came to realize…
zigGIS 2.0.2 Enhancements Announced
Abe posted today about upcoming enhancements in zigGIS 2.0.2. These changes address some of the most common feedback that we’ve heard from users. Abe has been working hard to get these changes implemented and released in a timely fashion. Testing will begin shortly. In addition to the flexibility that Abe describes, these changes also begin…
zigGIS 2.0.2 Getting Closer
Abe announced via Twitter today that zigGIS 2.0.2 will be available in about a month. This a small but significant release becuase zigGIS will now support the generic PostGIS “GEOMETRY” type. Because ArcGIS expects homogenous feaure classes, zigGIS will ask the user to choose a geometry type for the the specified GEOMETRY-typed column. So, if…
Odds and Ends (SpatiaLite and Stuff)

We established a new presence in Colorado Springs (I’ll be traveling there at the end of January). Additionally, I’ve been busy with project work…
Writing GeoJSON from SharpMap, Part 1
In between proposals, white papers and the like, I’ve been able to do a little coding to keep myself sane. Recently, I have been playing with SharpMap, GeoJSON and OpenLayers. But not necessarily in that order. Originally, I was looking over the GeoJSON spec to get more of a feel for it and decided that…
Using ArcSDE 9.3 with PostgreSQL, Part 3.5
I thought I was done with the series a while back but I’ve been getting a steady stream of questions through other channels so I thought I’d wrap up a lot of the common stuff in another post. Most of the inquiries come from people trying to integrate ArcSDE for PostgreSQL with open-source tools in…
A Good PostGIS Overview…
Steven Citron-Pousty gave a talk on PostGIS and has helpfully posted his slides here. It’s a good introductory overview and provides some good examples of basic spatial SQL in PostGIS. With ArcGIS Server now supporting PostgreSQL as a back end RDBMS and also supporting the use of PostGIS geometries, a lot of new users may…
zigGIS Source Code and Schwag Available
Abe has announced that the source code for zigGIS is now available (governed by the zigGIS EULA). It can be found at http://www.obtusesoft.com/source.aspx. Additionally, there is now zigGIS apparel available at http://www.cafepress.com/obtusesoft (just because it’s fun…and a little geeky). No, there is not an option to have the source code printed on a shirt. Enjoy…
