  • Moving Forward with Open Source GIS

    Now that we have our PostGIS/PostgreSQL running just about perfectly on our RedHat server, it is time to move forward with UMN Mapserver. I’m excited to see how much we can do with it and I think it will open up so much more to our products than .NET and ArcIMS ever did. As I said earlier, I want to make a front end that looks the same to the end users, whether we use ArcIMS/ArcSDE on the back end or Mapserver/PostGIS. In my previous post, I said that the GUI just wasn’t there for PostGIS, but letting it sit on a Linux server hosting our data should be great.

    This should be a great week as we start playing with Mapserver/PostGIS and seeing what we can do with it.

  • More About ESRI ArcIMS 9.1

    In my previous post, ESRI ArcIMS 9.1, is there a point? I asked why didn’t ESRI spell out the changes in ArcIMS 9.1. Well I just noticed there is now a whitepaper outlining the changes and new features of ArcIMS 9.1. This is exactly the information I was looking for, but it was buried in ESRI’s support site. If there was ever a reason to have RSS feeds for support, this is it. I’m sure there is much that gets posted in the knowlege base that most users of the support site never see unless they perform a search. I’d love to get feeds of the latest posting of all support site software, Arcscripts and knowlege base/whitepaper articles. That would be killer!

    Most of the changes are evolutionary as opposed to revolutionary, but that is fine. I’d prefer stability on the server side and ArcIMS 9.1 seems to do this. There is only one concern I have:

    The ArcXML Guide is provided only in HTML format.

    Why do this? Personally I always work off of printed material rather than help or websites for the AXL reference. It doesn’t look like there are many changes in the AXL since 9.0, but the future scares me. Moving from printed manuals to PDF was difficult enough, but not even providing a way for us to print them out on our own just hurts. Hopefully ESRI will revisit this and make sure that in the future PDF manuals are an option.

    Tomorrow we’ll start testing our existing ArcIMS 9.0.x applications with 9.1, but I’m guessing they will work without any modifications. I’m looking forward to see how it works.

  • ESRI ArcIMS 9.1, is there a point?

    Well I’ve had some time to look at our ArcSDE 9.1 and ArcIMS 9.1 and I’m not really sure if either needs to really be upgraded. I think I’ll upgrade ArcSDE because we don’t really do and direct programming with it so I’m sure ArcCatalog can connect fine and I’m sure our existing ArcIMS sites will still work find, but I’m at a loss about what I should do with ArcIMS 9.1. The only really updated part that interests me is support for Tomcat 5. We don’t use ArcIMS on Unix or Linux so its not a big deal that they are at the same level as the Windows support and I don’t really see anthing on ESRI’s site telling me that there is anything new with the .NET or ActiveX connectors. The WMS Connector is something we’ve looked at but its nothing we are currently playing with.

    Both my ArcIMS installs are working fine so I figure lets just go with ArcIMS 9.0.x and not play with fire. The what’s new webpages are nice, but I’d love to see something like a changelog or more detailed writeups of what is new.

  • Designing a front end

    I manage a GIS at a small company in Tempe, AZ. We’ve been designing web based GIS sites since the old ArcView IMS extension. We’ve moved from MapObjects IMS to ArcIMS 3,4,9 and now we’ve begun to look at UMN Mapserver. Basically we’ve heard from clients that they are having problems with the cost of maintenance of ESRI products. If we could eliminate ArcIMS/ArcSDE for these people and still provide our look and feel, this might be a market worth looking into. I’d love to make our sites work with any backend that the client wants. We’ve used .NET in our latest products, but maybe PHP or JSP would be a better choice for doing this. I’m just not sure what to think at this point, but I’ve got our database programmer looking at getting PostGIS and Mapserver installed on our Linux server.

    It’s going to be quite a move from ArcIMS/ArcSDE/Oracle, but maybe we’ll learn something. I’ll post more about this next week when we get it installed.
