Air Pressure Changes

Above is the chart of air pressure changes I encountered yesterday in travelling by air and car and recorded by my watch. It takes a reading every 15 minutes. Click the chart if you want to study it in greater detail.

GIS Class Resumes

This time it's GIS 215: Data Models. Wow.

Class started out with a discussion of some interesting things we are going to study this semester. Lots of stuff about the databasular workings behind the GIS data we work with. Later, we will do some GPS work which I am very much looking forward to. We will train on an expensive professional grade GPS unit the college has.

Then we had a lecture on databases in general and dove into some work on a step-by-step tutorial on using Access 2007. This was tedious and not too valuable to me. It did get me a little deeper into Access 2007 than I have been, and would have definitely been valuable for anyone in the class who had never used Access.

Above is a little screen capture from the exercise. All those fussy little data fields and labels and property sheets.

There are 7 people in the class, including Josh and Ben from last time. I miss Mary. Where is Mary?
