The roads, unfortunately, don’t line up with the Landsat images although both use the UTM coordinate system, the georeferencing of the Landsat images resulted in tjtorial positional error being introduced. You should now see a Landsat95 folder within C: You will be complete five of the Tutorial Part 1: We will have some hard copies of the relevant sections of the IDRISI tutorial available for you in the lab a scanned copy of the relevant sections here.
To check that the two import processes worked yaiga expected: Use Google Earth and Google Maps link to the map to familiarize yourself with the area.
GEOB Lab 3: Introduction to IDRISI
The roads should appear overlaid on the Landsat image. Include the same information as in the previous map, but provide an appropriate title. What is the formula i. As such, this is a long lab 6 hours is an estimate for the time required to complete this lab. Repeat for each city; you taaiga add more names if you like e.
Since remotely sensed images are large, please do not copy any data to your H: 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.
What information is being presented in this band’s image, and how could it be used? Zoom into the western part of the image somewhere just north of Chilliwack, ensuring that Hope is still visible.
When going through Exercise fyou must add a subtitle to the map that contains your name and lab section. Select a font size of Fraser Valley, [True colour image of Landsat bands 1, 2, 3] After the composite image appears, close the window and re-display the composite image using the Display Launcher so that the title appears at the top of the window.
To do this, you need to display band1 in blue, band2 in green and band3 in red.
The data for thtorial labs should be loaded into C: In the Tools menuclick on the Digitize tool looks like a bulls eye. Browse for the Roads file it should be the only choice. Click on Projects tab in the Idrisi Explorer window. Given the length of this lab, you should budget your time accordingly.
Read the first few pages about projects and working folders.
Supervised Image Classification and Lab 6: Click on the check boxand then click on the Since the first Output Idrisi image filename was converted to all uppercase, it would be better if you retyped that filename to follow the case of the other filenames. Define, with examples, qualitative and quantitative data. Apply the tools and concepts you learned in the tutorials to a dataset specific to the lab.
It sometimes takes a few minutes for Explorer window to refresh and for the new files appear in the listing. You will then import some Landsat data of the Fraser Valley and answer some questions pertaining to that dataset.
Hand in the printout of your Landsat image composition. Another window will appear, in which you enter the name of the city Caption. The naming convention for composite images is variable. Name the output file Landsat Remote Sensing Geob What wavelengths are captured by Landsat band 6? For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data:. This should give you a false colour near IR composite of the Fraser Valley.
From within the Raster Group, display Landsat 6 and Landsat Print your band 6 image.

Why is it used i. Name taaiga layer to be created Cities. What features in particular stand out in the image the ‘fuzzy worms’ 5.
