Open Source Geographic Information Systems 189
RGillig writes "The second MapServer Users Meeting and the first ever Open Source GIS Conference was held on June 9th to 11th in Ottawa, Ontario, Canada. The initial response from the Open Source GIS community is that the conference was a huge success. It was great to have people from private, government, academia, and communities all together discussing how Open Source GIS applies to their needs. Here is a presentation given by Paul Ramsey, Director, Refractions Research Inc. that outlines the current state-of-the-art for Open Source GIS, and includes links and information about all of the current software packages/efforts, etc."

This note from the briefing is most telling:
Note: The saturated commercial market for cartography tools, the high level of effort to achieve a usable tools, and the appeal of other cutting edge projects have combined to deter any active development on user-friendly paper map production tools. As with the OpenOffice experience in Linux, it would probably require a dedicated multi-year funded project to produce a core product with sufficient technical mass that an open source community could reasonably continue with enhancements and support.
In other words, don't expect to find a complete open source end-user application within your lifetime.
This is, alas, common in the open source world. Everybody does their own toolkit that does 90% of what other toolkits do, adds 10% of its own, and assumes that the user is a person who gets their jollies from writing code, not actually using the application with production data.

The comment you quoted addresses the specific topic of cartographic map generation suitable for printing. I don't see any reason that several of the existing projects can't include respectible map production suitable for most GIS end users.
Furthermore, as noted, a serious cartographic production system could be implemented within a couple of years given an appropriate project to drive it.

I've worked for one of the largest regional planning agencies in the country, for a ~100,000 person city, with planners and environmental types at at U of Michigan, and done a fair bit of GIS work on my own. ~95% of that work has been with ESRI products. Except for some specialized spatial statistics software, and equally specialized transportation modeling packages, ESRIs stuff is (sadly) hard to beat.
The (paying, non-researcher) end-user, a GIS lackey in a planning office somewhere, someone doing work for some environmental group or maybe someone doing marketing analysis, is not going to deal with the hassles that most open source packages involve. The most successful open-source end-user programs tend to be things with a _huge_ amount of interest in them. You know, web browsers, mail clients, desktop publishing, etc. GIS is still kind of a niche market. Maybe I'm totally off-base in assuming this, but my feeling is that ESRIs core customers are the big metropolitan planning organizations and those are _incredibly_ slow moving organizations for the most part. IMO, there has to be a lot of oomph behind a project before it gets polished enough that Joe Blow, Metropolitan Planner, is going to use it.
I love the idea of GRASS, but I don't see it ever out-doing ArcGIS. Open-source GIS needs to find a big, untapped market and branch out from there. I think what the open source GIS community needs to do is focus on a very stripped down package, as easy to use as a web browser, that lets the average person download TIGER line files from census, import ESRI shapefiles, add their own GPS data, with a big open source library of maps for people to play with. Leave out the analysis tools altogether, deal with things like map projection behind the scenes, and let people use GIS to plan gardens around their house, etc. Once you've got people using that, bloat the software from there, rather than slowly adding features to an already buggy, difficult to use package.
The other extreme of the spectrum is the high-end GIS work, where you've already got serious computer nerds working, and where there's always a market for a product that cedes some control back to the user, even if it is at the expense of some day-to-day usability. Thats where open source is already making inroads.
