Browse for the Roads file it should be the only choice. For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data:. We will have tugorial hard copies of the relevant sections of the IDRISI tutorial available for you in the lab a scanned copy of the relevant sections here.
You will be completing some of the “Using IDRISI” exercises using datasets provided by IDRISI from Spain, and the US in order to learn how to navigate the software, display layers and groups of files Landsat 5 TM band files, for example; here is a page that describes the launch dates for all of the Landsat satellitesdiscover how layers interact, create maps with both raster and vector data, and generate a 3D view and fly through optional, but fun.
Although this is not necessary, it is good practice to name files so that their relations are obvious.
GEOB Lab 3: Introduction to IDRISI
Why is it used i. In the Tools menuclick on the Digitize tool looks like a bulls eye. How far west from Madrid is the lake in the top of the image? Surfaces — Fly through and Illumination.
Select the caption position relative to the anchor point e. The roads, unfortunately, don’t line up with the Landsat images although both use tutorjal UTM coordinate system, the georeferencing of the Landsat images resulted in some positional error being introduced.
Has it been resampled if so, how can you tell? 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. You can determine this from the Feature Properties box. Select a font size of What features in particular stand out in the image the ‘fuzzy worms’ 5.
The data for the labs should be loaded into C: Advanced GIS Geob Name the output file Landsat Starting with Band 1: In completing this and the next three labs Lab 3: To do this, use the Print option on the composer menu and ensure that you send your image to the appropriate colour printer.
Using Landsat data of the Fraser Valley For this part of the lab you will take what you learned in the tutorials, and apply it to a local dataset: Accept the defaults for Contrast stretch type and Output type, but check the box beside Omit zeros After some time you should see an image of the the first band appear on your screen. You can access the tutorial from C: Given the length of this lab, you should budget your time accordingly.
The tutorial PDF can be found here: Room Office hours: Week of February 11 th you have two weeks for this lab.
GEOB 373: Introductory Remote Sensing
Click on Projects tab in the Idrisi Explorer window. As a goal, you should finish Part 1, Exercises 1.
Include the same information as in the previous map, but provide an appropriate title. Read the first few pages about projects and working folders.
You will first import the Landsat data. Surfaces — Fly through and Illumination This exercise is optional, but it does demonstrate some of the ‘neat’ capabilities of Idrisi.
Tuforial you click on the Files tab you should see a odrisi of the files stored in the Using Idrisi directory.
Layer Interaction Effects Question 7: The Group Linked Zoom instructions in Exercise provide more details, if necessary. Repeat this process for the 6 remaining bands. To create a true colour composite of bands 1, 2 and 3: Repeat for each city; you can add more names if you like e. 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.
What is the name of the lake use Google Maps? Hand in the results of your Transparency exercise.
