Note that Exercises 1.

To do this, you need to display band1 in blue, band2 in green and band3 in red. Layer Interaction Effects Question 7: For this part of the lab you will take what you learned in the tutorials, and apply it to a local dataset: Layer Interaction Effects 1.

Select a font size of Using Landsat data of the Fraser Valley Sela this part of the lab you will take what you learned in the tutorials, and apply it to a local dataset: What is the formula i.

While many people place the band numbers following a short-to-long wavelengths convention e. Note that this term differs from orthophoto.

### GEOB Lab 3: Introduction to IDRISI

Print your band 6 image. Loading the data Using Windows Explorer, go to: Navigation Map Query Question 9: 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. Set the map scale RF toomitting the idris when specifying the scale; right-mouse clicking within the image allows you to specify the map scale.

After some time you should see an image of the the first band appear on your screen.

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 manuzl the top of the window. Hand in the results of your Transparency exercise.

Browse for the Roads file it should be the only choice. Select Text as the Layer Type. Remote Sensing Geob You should now see a Landsat95 folder within C: Room Office hours: To do this, use the Print option on the composer menu and ensure that you send your image to the appropriate colour printer. Review the material presented in Exercise if you need a reminder on all of the specific instructions on preparing and printing a map welva.

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

## GEOB 373: Introductory Remote Sensing

What features in particular stand mamual in the image the ‘fuzzy worms’ 5. What is the name of the lake use Google Maps? In completing this and the next three labs Lab 3: Read the first few pages about projects and working folders.

Note that we don’t have Band 6L or 6H data. 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 mankal the roads as imaged in the Landsat images.

REF The Landsat images have been georeferenced to a UTM [zone 10, North] coordinate system, so if we assign odrisi same georeference system to the roads [knowing that roads had previously been projected to a UTM coordinate system within ArcGIS], the roads and the Landsat images will be geographically referenced together. For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data:.

Using Windows Explorer, go to: Then, 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.

You may not need to save your work if you answer the questions as you go.

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.

This will save your composition for further editing.

Right click on the existing pathname which might be C: Surfaces — Fly through and Illumination This exercise is optional, but it does demonstrate some of the ‘neat’ capabilities of Idrisi. Introduction to Image Analysis: Name the layer to be created Cities. You will be completing some of the iddrisi 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.
