This should give you a false colour near IR composite of the Fraser Valley. Note that the project and working directories you will be using are different from those specified in the tutorial on page 6, Exercise d and e: You will then import some Landsat data of the Fraser Valley and answer some questions pertaining to that dataset.

Introduction to Image Analysis: What features in particular stand out in the image the ‘fuzzy worms’ 5.

You will be complete five of the Tutorial Part 1: What wavelengths do bands 5 and 7 capture, and what feature characteristics do they, in particular, highlight? The roads, unfortunately, don’t line up with the Landsat images although both use the UTM coordinate system, the georeferencing of the Landsat images taita in some positional error being introduced.

If you are finished, print your map composition using the Print command in the Map Composer. In the Explorer window, click on Files and you should see all 7 bands listed. Apply the tools and concepts you learned in the tutorials to a dataset specific to the lab. Describe the strengths of each of the three images Landsat, Landsat, band 6 you have explored above, in aiding you with respect to interpreting the landscape.

Zoom into the western part of the image somewhere just north of Chilliwack, ensuring that Hope is still visible. Surfaces — Fly through and Illumination This exercise is optional, but it does demonstrate some of the ‘neat’ capabilities of Idrisi.

Hand in the results of your Transparency exercise. Zoom into the area just southeast of Chilliwack where Hwy 1 runs more or less due east-west, and use the Measure tool to determine how far off in a north-south direction only the vector roads are from the roads as imaged in the Landsat images.
