First SurveyOS Project Video Tutorial For OpenJUMP

I was able to actually get outside and do some “real mapping” work over by vacation last week. I took out a recreational grade GPS receiver and a digital camera and started collecting data for the East Stockton Survey Control GIS project that I am working on. I was only able to visit two sites, but it felt good to get my hands “dirty”.

I find that I spend almost all my time with GIS as a programmer, and not enough as an end user. I think this is dangerous, since one of the most powerful things about open source software is that is used by the people that design and maintain it. I hope this project and two others I am working on will help me do more a little more “using” of OpenJUMP and a little less “designing and maintaining” of OpenJUMP. I believe the end result will be better programming on my part.

I had originally planned on writing some documentation about my use of OpenJUMP on East Stockon Survey Control GIS. I may still do that, but have decided that digital video would be a much better media form for this type of information. I’m currently trying to get my Debian Linux box set up for capturing and editing digital video. When it is ready to go I’m going to spend some time on a tutorial video that shows the viewer how they can collect GIS data in the field with relatively inexpensive equipment and then convert this data into features using OpenJUMP. I’ve already got some video footage from the project and have started working on the outline of the tutorial. I’ll keep you guys posted on my progress. I think I may have a video ready in a couple months.

Free GIS Book Update

Over the weekend I added a little content to the “Math for Maps” chapter of the OSGeo's Free GIS Book. It's the short introduction to the section in the chapter that is about the measurements made to create maps or spatial data.

You find the chapter here:

I'll start on the measurements section of the chapter next weekend, with some material on measuring distances. Hopefully I'll have time to write a couple of sample problems.
