zigGIS 3.0 To Be Open-Source

Update: zigGIS has been discontinued.

Abe officially announced today that the next major release of zigGIS, version 3.0, will return to open-source. This announcement was followed up with a message on the zigGIS Google Group. A snippet of that message is here:

We have some exciting news. The next version of zigGIS will officially return to being truly open source. That means zigGIS 3.0 will be free to download and use.

Of course this doesn’t mean zigGIS 3.0 will be free to develop. Though zigGIS is held near and dear to the hearts of the Obtuse Software team it cannot be developed on love alone. So we we’ll be seeking funding in ways alternative to selling licenses. We’ll follow a more traditional open source model of accepting personal donations and corporate sponsorships and selling support contracts.

Version 2.x will continue to be supported on the forums here and licenses sold at obtusesoft.com. However, all funds will be applied directly to the development of 3.0.

I’m glad that zigGIS is returning to its open-source roots. Since the release of 2.0, the zigGIS user community has grown a lot and there has been interest from other developers in extending it in new ways. I am excited by the prospect of the involvement of a wider community of users and developers in its advancement.

A Look at “PostGIS In Action”

Over the past few weeks, I have been reading a copy of the upcoming book by Regina Obe and Leo Hsu titled “PostGIS In Action.” Through my work with zigGIS and some of my consulting work with Zekiah, I have been using PostGIS with good results for some time now. I have found that it matches or exceeds the capabilities of its commercial counterparts and I can be quite productive with it.

Regina has been a frequent contributor to zigGIS discussions over the years and her expertise with PostGIS has definitely helped Abe, Paolo and I as we have worked on it. Also, many tips from the Boston GIS blog/site have been very helpful so I have been looking forward to this book for some time. Continue reading “A Look at “PostGIS In Action””

Crazy Times – Coming Up For Air

It’s been an extremely busy few months, as evidenced by the pace (or lack thereof) of blogging. I have been hopping between customer sites, mainly helping with ArcGIS Server implementations. We’re also re-hosting an ArcIMS site for someone. I expect that to eventually transition as well but we have to get it moved first. I’m also working a pro-bono implementation of PostGIS/GeoServer/OpenLayers for the town of Green Mountain Falls, Colorado. That’s been fun. It’s great to see how a small town can marshall it resources (Boys Scouts with GPS collected trails as an Eagle Scout project) to get things done. The initial implementation will be simple as they are more interested in getting their data out there but then we’ll circle back around to address public-service-type applications after that.

Significant changes are coming for zigGIS. Abe, Paolo and I have been laying out a roadmap for its way ahead. Look for an announcement soon via zigGIS on Twitter.

I have been having a lot of fun with the REST-based APIs from ESRI (Javascript, Flex, Silverlight/WPF). In particular, I’ve been happy with how extensible they are in terms of being able to support new data sources.
OpenLayers 2.8 and GeoExplorer are also on my radar but that radar screen is getting pretty crowded.

All of this with less than a week to go before vacation. Whew!

zigGIS Photos

Paolo was kind enough to post photos of the zigGIS team from our time in New York. You can find them here. This was the first time the three of us had met up and we had a great time.

We had some discussions about the way ahead for zigGIS and there are some big things in store that we’ll announce as we firm them up.

It was also great of Brian Flood to come out and hang for a bit.

zigGIS Tweet and Greet

After being involved with zigGIS for a couple of years now, I’m excited that Paolo Corti is going to be visiting the States next week and that Abe and I will finally get to meet him (and vice versa). The three of us will be meeting at the Lolita Bar in New York City at 6pm on April 24th.

If you’re in the area (or you want to make a special trip), we could use all the help we can get to give Paolo a warm welcome to the US. I hope to see you there. Tweet us if you think you’ll make it.

A frosty cold helping of zig.

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 that there are numerous workflows that can be employed to create spatial tables in PostGIS and many of these don’t necessarily register in the geometry_columns table. For example, you can use a standard CREATE TABLE to create a table that includes a geometry column. In this case, the table will not be registered but will still be a valid spatial table. The same can be said for views. Continue reading “Using PostgreSQL Views in zigGIS 2.0.2”

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 to position zigGIS to support other data sources beyond PostGIS.
