What information is being presented in this band’s image, and how could it be used? The naming convention for composite images is variable. Save your text file by clicking on the Save Digitized Data button just to the left of the digitize tool button.

Supervised Image Classification and Lab 6: Note that this term taiba from orthophoto. Include the same information as in the previous map, but provide an appropriate title. Add the three imagebands band1 as blue, band2 as green, and band3 as red.

Accept the defaults for Contrast stretch type and Output type, but check the box beside Omit zeros Click in the image window where you want the beginning of the text to go. You will then import some Landsat data of the Fraser Valley and answer some questions pertaining to that dataset. If you click on the Files tab you should idfisi a list of the files stored in the Using Idrisi directory. 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.


This will save your composition for further editing.

Double-click on the zip file Landsat Layer Interaction Effects Question 7: You will be completing the following exercises for this lab: For these exercises, you will be working with data from Westborough, Mass. Using Landsat data of the Idriis Valley For this part of the lab you will take what you learned in the tutorials, and apply it to a local dataset: 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.

Click on Map Properties Add a north arrow and a scale bar. Fraser Valley, [True colour image of Landsat bands 1, 2, 3] After the composite image iddrisi, close the window and re-display the composite image using the Display Launcher so that the title appears at the top of the window. In the second week, complete the rest of Part 1, Exercises 1.

What wavelengths do bands 5 and 7 capture, and what feature characteristics tuutorial they, in particular, highlight?

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? The goal of this lab is to give you the foundations tutrial working with IDRISI, the image processing program that you will be using in all of your subsequent labs, and for your final project.


GEOB Lab 3: Introduction to IDRISI

Repeat for each city; you can add more names if you like e. 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.

Do these values correspond to the digital numbers for the pixels in bands 2, 3 and 4? What wavelengths do each band capture, and what feature characteristics does each band, in particular, highlight?

GEOB 373: Introductory Remote Sensing

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 some positional error being introduced. What is ordinal, or ranked, data?

What is the name of the lake use Google Maps? Layer Interaction Effects 1. 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:. Since remotely sensed images are large, please do not copy any data to your H: Add text labels for Hope, Harrison and Chilliwack you can add more if you wish:
