Hi Ian, I believe you're getting things mixed up here. Buying commercial software doesn't simultaneously buy you a lot of commercial high quality map data (at least not here in Europe). It's two seperate things altogether. You always have to have suitable map data regardless of what software you use. And usually, web mapping solutions are built for customers that already have the data to use in it anyway.
You mention geocoding, but that's not a web mapping issue either, imho. Web mapping is not desktop GIS. The data are usually prepared before they are published, e.g. by geocoding it. So usually that's been taken care of in advance, probably with a commercial geocoder, or by shear database gymnastics, maybe in connection with a commercial desktop GIS. Nothing in the above speaks against using Mapserver. True, there are no immidiate Open Source geocoding solution available, but that's imho more due to the complexity of the task, not due to inherent restrictions in Open Source nor Mapserver. You can still use MapMarker or whatever geocoder you prefer, and publish the data with Mapserver. However, geocoding solutions are probably being offered as web services from now on anyway, which makes this whole discussion rather superfluous. You're talking about the cost break down, so let me bring another ball into play: the cost of commercial software itself versus the development cost of building the solution (with free/Open Source software). Commercial Internet software is almost always very expensive, leaving amble economical room for developing the solutions for the saved cost - a task that's usually also required with commercial software btw. It's a common mistake that Open Source only equals cheaper solutions, it could just as easily result in better solutions (for the same cost). And another advantage of no immidiate software costs is that you have free scalability, i.e. you can keep adding an unlimited number of web mapping servers to cope with increased user demands at only the cost of hardware + setup. Example: what's the pure software price for say 5 servers with 4 state-of-the-art processors running MapXtreme (or GeoMedia or ...) ? Pretty high I should say. With Mapserver (on Linux) : 0 $. On the technical front: CGI is not a security hazard, it's a *potential* hazard. Properly configured, CGI can be just as safe, or better, as e.g. ASP with IIS. I'm using MapScript (Mapserver in PHP), and the underlying PHP interpreter _can_ be set up as an Apache module, which should satisfy our safety concerns wrt. CGI. It's simply not a real problem. > Now if we could generate some momentum for an Open Source geocoding, routing, and > street data solution, then we might be on to something.... I agree. And I'm sure somethings already on its way as we speak. Best regards/Med venlig hilsen Lars V.
