GeoMedia Viewer Now Available for Download!

Posted by jeffhobbs on May 6, 2009

In the way old news section of the blog, it was brought to my attention a while ago that you can now download the GeoMedia Viewer from the Intergraph web site. For a long time, you had to make a request from product support and then Intergraph would send you a CD with GeoMedia Viewer on it. As of late last year or early this year that changed. You can now download it from Intergraph Support site. https://support.intergraph.com/Product/GeoMediaViewer.asp Please note, although it’s on the Intergraph’s support site, I do NOT believe you need to login to download. So, if you’re looking for a tool that will do any of the following:

  • Read a GeoMedia/GM Pro workspace
  • Connect to Oracle Spatial and SQL Server
  • Have the same look and feel as GeoMedia and GeoMedia Pro
  • Free

You’re definitely in luck. I’d encourage you to download it and give it a try. Please note that if you’re going to install GeoMedia Viewer on a machine already running GeoMedia and/or GeoMedia Pro, I believe Intergraph recommends you install the least functional piece of software first. In other words, if you’re going to run (not sure why you would want to) GeoMedia, GeoMedia Viewer, and GeoMedia Pro all on the same machine, you’d want to first install GeoMedia Viewer, then install GeoMedia Std, and finally install GeoMedia Pro. If you don’t follow this pattern, you might find that some of your functionality is lost.

From the GeoMedia Viewer site:

GeoMedia Viewer is an easy to use, FREE GIS software application for desktop viewing and distribution of geospatial data. It allows an organization to maximize the value of its geospatial data by extending availability to novice users who wouldn’t otherwise have access because of the barriers of purchasing and learning how to use a full GIS software application.

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.
