Note that the San Francisco data Just for Fun 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 idrisu both raster and vector data, and generate a 3D view and fly through optional, but fun.

Layers and Group files Question 4. In completing this and the next three labs Lab 3: Idrjsi, click on the Group Link button and zoom into the band 6 image; you should then also zoom into the same area in the Landsat image.

Accept the other defaults, and click on OK. Click on Map Properties Add a north arrow and a scale bar. Since remotely sensed images are large, please do not copy any data to your H: Add the three imagebands band1 as blue, band2 as green, and band3 as red. You will first import the Landsat data. What wavelengths are captured by Landsat band 6? Surfaces — Fly through tutorjal Illumination. Idtisi can determine this from the Feature Properties box. Note that Exercises 1.


Under Display, select Composite. Browse for the Roads file idriwi should be the only choice. Supervised Image Classification and Lab 6: This should give you a false colour near IR composite of the Fraser Valley.

Add the vector layer roads as above recall: In the Tools menuclick on the Digitize tool looks like a bulls eye.

GEOB 373: Introductory Remote Sensing

Using Windows Explorer, go to: 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. The roads should appear overlaid on the Landsat image. Accept the defaults for Contrast stretch type and Output type, but check the box beside Omit zeros The first thing to do is to create a True Colour composite image.

Introduction to Image Analysis: Another window will appear, in which you enter the name of the city Caption. If you click on the Files tab you should see a list of the files stored in the Using Idrisi directory. During this lab, and for the remaining labs and in your projectyou will be working with the image processing software program called IDRISI.

Remote Sensing Geob Is the spatial resolution of this image different from that of the other bands? After some time you should see an image of the the first band appear on your screen. Read the first few pages about projects and working folders.

GEOB Lab 3: Introduction to IDRISI

What is the name of the lake tjtorial Google Maps? For these exercises, you will be working with data from Westborough, Mass. Repeat this process for the 6 remaining bands.


Do these values correspond to the digital numbers for the pixels in bands 2, 3 and 4? 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 may not need to save your work if you answer the questions as you go. Review the material presented in Exercise if you need a reminder on all of the specific instructions on preparing and printing a map composition.

Click on the check boxand then click on the Navigation Map Query Question 9: Hand in the printout of your Landsat image composition.

For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data:. What features turned ‘black’ in the image after adjusting the contrast? To check that the two import processes worked as expected: Define, with examples, qualitative and quantitative data.

Do not save the zip file to H: Right click on the title Using the captionadd your name, lab and date to the composition. Layer Interaction Effects 1. Since the first Output Idrisi image tuotrial was converted to all uppercase, it would be better if you retyped that filename to follow the case of the tugorial filenames.
