Thinking in GIS

My friend Diego Guidi is the smartest GIS/.NET developer I personally know here in Italy. He is the developer of NetTopologySuite, the port in the .NET world of the popular Java's JTS Topology Suite from VIVID Solutions. I wanted, sooner or later, write some stuff here about WMS and TMS, and now I am very happy that Diego asked me to publish this brilliant article about this topic.First of all, let me thanks Paolo for hosting this post! I hope that this article can be interesting and useful like other stuff that you can find here...IntroductionThere are a lot of...

Some friends already spoke me well about FeatureServer by Metacarta in the last weeks, so I already was waiting for having a bit of time to get started with it.

In the last post I showed you a configuration for serving Ruby on Rails applications with Mongrel cluster and Apache in a *nix environment (Ubuntu).With this post I will reproduce the same configuration in a Windows environment.The main difference in Windows is that you cannot use the mongrel_rails command with the cluster option (provided by the mongrel_cluster gem) that relies on daemonize functionality, only available on *nix platforms.What you will need to do is to manually create n Mongrel services for the n clusters you will need. Let's see how to do that.Install Ruby, gems and then install...
