On Tuesday,ÃÆ'‚  October 13, we will meet workers from Seattle Urban Nature (SUN), a community group, at Piper's Creek in northwest Seattle to see how vegetation surveys are performed. The purpose is to see one example of how the the kinds of data used in GIS maps (such as those we looked at last week in the ArcIMS lab) and models (such as DHSVM, which we study later in the quarter) are gathered. This experience should give you a better picture of the kinds of compromises that are made to compose maps and build environmental simulation models.

Dr. Miles Logsdon's Ocean 452 class uses Big Beef Creek, which flows into Hood Canal, as a site for students to make their own surveys of vegetation and other properties. They then use GIS software to construct maps like those we have studied using ArcIMS. We will look at a very simplified version of this procedure.

The Lab 2 Assignment will be due next Tuesday, Oct 20th before class. You can either email an electronic copy, or bring a hard copy to class
