Thinking in GIS

As many of you can have already read, ArcSDE for Postgres is coming out at ArcGIS 9.3 (it is currently in the release candidate state). It will let you store geometries in two formats, Esri geometry and PostGIS geometry, in the same fashion ArcSde for Oracle is letting Esri or Oracle geometries be stored. I have seen some interest in the GIS community about this new, and i was reading interesting posts by Bill Dollins, Paul Ramsey, James Fee and Dave Bouwman, so I thought i would post here my opinion. Plus, as some of you may already know, zigGis...

It is very easy to get started with the MapFlashViewer Framework in the ASP .NET Implementation (C#) I talked about in this post. This implementation was written using ActiveX Connector for ArcIMS 9.0 and C# MapScript for MapServer 4.10.0. You can easily adapt the code for previous or next versions.Open the solutionYou will find several files in the C# ASP .NET project included with the solution you downloaded:A simple default.aspx web form with the MapControl user control over itA form test.aspx for debugging purpose (you don’t need unleass you are in troubles)the Controller (responsable for translating request/response to the...

The most common approach is to write javascript client code to perform the main GIS actions (zooming, panning, etc etc).There is also some example of Java applet GIS web interface, but...
