Next GeoMedia Minor Release 6.1.6 Available for Download

Posted by jeffhobbs on October 7, 2009

Sorry, a bit late on the update. Intergraph released GeoMedia Minor Release 6.1.6 in the middle of last month. I posted it on the GeoMedia Wiki, but didn’t get a chance to post it on the blog. On a side note, if you subscribe to the GeoMedia Wiki “Product Announcements and Software Updates” page on the wiki, you’ll receive an email whenever that page is updated. So when a product announcement is posted e.g. the release of a minor release, you should receive notification via email.

Analyze Geometry

Posted by jeffhobbs on May 6, 2009

Sorry about the long time between posts. I’m not giving up on blogging, but, believe it or not, it does take a lot of time….

Anyhow, I’ve been playing a little with the Analysis > Analyze Geometry command. I can’t say I use it all the time, so I’m not sure when this changed. It may have been a long time ago. I’ve always found it hard to get lat/long coordinates from my state plane coordinates. Yes, I can do this one off by just clicking on the map and getting a coordinate readout from the “Precision Coordinates” dialog, but what if I wanted to have lat/long for 10,000 points. That was much harder.

You can do this with functional attributes. In fact, I posted an article on www.geomediawiki.org on how to do it. It was actually copied for the most part out of the GeoMedia online help. However you can also do this with the Analyze Geometry command.

  1. Launch the command (Analysis > Analyze Geometry)
  2. Choose a point feature class. If you have lines or polygons, use the CENTERPOINT functional attribute to create points from the line/area geometry.
  3. When you select the point feature class, you will see the “Analysis Options” dialog populate. In the dialog you will see “Geographic Coordinate” and “Projection Coordinate”
    analysis_options
  4. If you check “Geographic” you will get lat/long. If you check “Projection” you’ll typically get easting/northing. NOTE: you can set the output coordinate format in the “Units and Formats…” dialog in the same Analyze Geometry dialog.
  5. For points you have options for Azimuth, Bearing, Geographic Coordinates, Projection Coordinates, and Height. Height assumes you have the Z elevation populated in your geometry
  6. If you work with lines, you’ll have options for Length, Azimuth, and Bearing
  7. If you work with areas, you’ll have options for Area, Perimeter, and Area/Perimeter ^2

All in all, this is much easier than having to write a functional attribute.

GeoMedia Wiki Officially Launched at the Intergraph User’s Conference

Posted by jeffhobbs on June 10, 2008

After quite a bit of coordination with Intergraph on this matter, Intergraph officially launched geomediawiki.org today. We’ve actually had the site up and running for a month or so now. However it’s only in the last few weeks when Intergraph began looking at contributing Intergraph staff time to the project. As it stands now, the wiki is hosted on a 3rd party wiki server (wikispaces.com). The URL is owned by me and Intergraph is sponsoring the site both at a financial and also a staffing level. All of the content on the site is licensed under the Creative Commons Attribution 3.0 license.

So, for everybody that read and posted on the GeoMedia Wiki entry from April 24, here’s your chance to start contributing! The wiki has been setup where anybody and read the wiki and people that sign-up and login can edit any piece of the wiki. Once you sign-up on Wikispaces, you must request contributor access to GeoMedia Wiki. Once you request access, the wiki organizers are emailed and then we approve your access. It’s that simple!

With the wiki we are welcoming all contributions. If you have something you feel others would benefit from; it belongs on the wiki!

Last but not least, with the creation of the wiki you will see less tutorial-based content posted on my blog. Instead I will be posting more Intergraph and GIS related content which I think might be useful for my readers. I WILL still be creating tutorials and work flows, however much more of this will be going on the wiki as it’s really a much better place to house such content.
