Add text labels for Hope, Harrison and Chilliwack you can add more if you wish: When you use the Ortho tool, you are creating an orthographic image.

One of the first steps you must complete before starting most Digital Image Analysis DIA projects is to import the data i. Surfaces — Fly through and Illumination This exercise is optional, but it does demonstrate some of the ‘neat’ capabilities of Idrisi. The goal of this lab is to give you the foundations for working with IDRISI, the image processing program that you will be using in all of your subsequent labs, and for your final project. What does NDVI stand for? To create a true colour composite of bands 1, 2 and 3: The differences between raster and vector data are discussed throughout the exercises, although Exercises and in particular cover the material you should use in your answer to this question.

However, remember that with this experience you can put down in your resume that you have some working knowledge of image processing. For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data: Dirisi should give you a false colour near IR composite of the Fraser Valley.
