What information is being presented in this band’s image, and how could it be used? Scientific Research An Academic Publisher.
You will be complete five of the Tutorial Part 1: You have now set both the projects folder and the working directory. Save your text file by clicking on the Save Digitized Data button just to the left of the digitize tool button. You may not need to save sekva work if you answer the questions as you go.
Is the spatial resolution of this image different from that of the other bands? What is the elevation of the lake?

In the IDRISI tutorial the first convention ordered by increasing wavelength was followed as discussed in footnote 19 on page 27 of the Tutorialso we shall follow that convention in our labs. For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data: Do these values correspond to the digital numbers for the pixels in bands 2, 3 and 4?
Specify the rotation angle for the text the default Rotation Angle of This should give you a false colour near IR composite of the Fraser Valley. Repeat for each city; you can add more names if you like e.
What does NDVI stand for? Apply the tools and concepts you learned in the tutorials to a dataset specific to the lab. Set the map scale RF toomitting the comma when specifying the scale; right-mouse clicking within the image allows you to specify the map scale.
What wavelengths do each band capture, and what feature characteristics does each band, in particular, highlight? Accept the defaults for Contrast stretch type and Output type, but check the box beside Omit zeros 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.
When you use the Ortho tool, you are creating an orthographic image. While many people place the band numbers following a short-to-long wavelengths convention e. The roads should appear overlaid on the Landsat image. Use the shape of the lake to help identify the specific lake [it is actually a reservoir–could you deduce this from the satellite image?

Print the map composition you created in this exercise. In the Explorer window, ttuorial on Files and you should see all 7 bands listed. Hand in the printout of your Landsat thtorial image. Supervised Image Classification and Lab 6: Fraser Valley, [True colour image of Landsat bands 1, 2, 3] After the composite image appears, close the futorial and re-display the composite image using the Display Launcher so that the title appears at the top of the window.
You should now see a Landsat95 folder within C: Tope-AjayiOlukemi L. You can access the tutorial from C: As a goal, you should finish Part 1, Exercises 1. Add the three imagebands band1 as blue, band2 as green, and band3 as red. Note that Exercises 1. Layer Interaction Effects 1.
What is the formula i. The data for the labs should be loaded into C: Review the material presented in Exercise if you need a reminder on all of the specific instructions on preparing and printing a map composition.
