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:. Although this is not necessary, it is good practice to name files so that their relations are obvious.

The first thing to do is to create a True Colour composite image.

Select a font size of Another window will appear, in which you enter the name of the city Caption. The naming convention for composite images is variable. Right click on the title Using the captionadd your name, lab and date to the composition.

Introduction to Image Analysis: From within the Raster Group, display Landsat 6 selga Landsat Navigation Map Query Question 9: What features in particular stand out in the image the ‘fuzzy worms’ 5. The roads should appear overlaid on the Landsat image. When going through Exercise fyou must add a subtitle to the map that contains your name and lab section. 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.

Fraser Valley, [True colour image of Landsat bands 1, 2, 3] After the composite idriisi 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. 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: How far west from Madrid is the lake in the top of the image?

However, remember that with this experience you idriai put down in your resume that you have some working knowledge of image processing. Select Text as the Layer Type. What wavelengths do bands 5 and 7 capture, and what feature characteristics do they, in particular, highlight?

Since remotely sensed images are large, please do not copy any data to your H: Click on the check boxand then click on the In the second week, complete the rest of Part 1, Exercises 1.

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. What wavelengths do each band capture, and what feature characteristics does each band, in particular, highlight?

Given the length of this lab, you should budget your time accordingly.

GEOB Lab 3: Introduction to IDRISI

nanual Note that the San Francisco data Just for Fun Add the three imagebands band1 as blue, band2 welva green, and band3 as red. Click on Map Properties Add a north arrow and a scale bar. You will then import some Landsat data of the Fraser Valley and answer some questions pertaining to that dataset. Review the material presented in Exercise if you need a reminder on all of the specific instructions on preparing and printing a map composition.


Is the spatial resolution of this image different from that of the other bands? Right click on the existing projects folder and select Change projects folder.

Hand in iidrisi printout of your Landsat image composition. Starting with Band 1: Select the caption position relative to the anchor point e. We will have some hard copies of the relevant sections of the IDRISI tutorial available for you in the lab a scanned eelva of the relevant sections here. Double-click on the zip file Landsat Displaying the data and creating images The first thing to do is to create a True Colour composite image.

Click on Projects tab in the Idrisi Explorer window. 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? If you click on the Files tab you should see a list of the files stored in the Using Idrisi directory. A vector file of some roads in this area is also provided.

To do this, use the Print option on the composer menu and ensure that you send your image to the appropriate colour printer. In the Tools menuclick on the Digitize tool looks like a bulls eye. Layers and Group files Question 4. The data for the labs should be loaded into C: What does NDVI stand for? Repeat for each manul you can add more names if you like e.
