Add the vector layer roads as above recall: What features turned ‘black’ in the image after adjusting the contrast? For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data:. A vector file of some roads in this area is also provided.

Repeat for each city; you can add more names if you like e. The roads should appear overlaid on the Landsat image. Surfaces — Fly through and Illumination This exercise is optional, but it does demonstrate some of the ‘neat’ capabilities of Idrisi.

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

Is the spatial resolution of this image different from that of the other bands? Zoom into the western part of the image somewhere just north of Chilliwack, ensuring that Hope is still visible. Given the length of this lab, you should budget your time accordingly. The naming convention for composite images is variable. Navigation Map Query Question 9: Select the caption position relative to the anchor point e.


Introduction to Image Analysis: Supervised Image Classification and Lab 6: One of the first steps you must idirsi before starting most Digital Image Analysis DIA projects is to import the data i. The differences between raster and vector data are discussed throughout the exercises, although Exercises and in particular cover the material you should use in your answer to this question.

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. Under Display, select Composite.

Browse for the Roads file it should be the only choice. Right click on the existing projects folder and select Change projects folder. How far west from Madrid is the lake in the top of the image? In the second week, complete the rest of Part 1, Exercises 1. Note that the San Francisco data Just for Fun Double-click on the zip file Landsat Select Text as the Layer Type.

As such, this is a long lab 6 hours is an estimate for the time required to complete this lab. Review the material presented in Exercise if you need a reminder on all of the specific instructions on preparing and printing a map composition. What is ordinal, or ranked, data? After some time you should see an image of the the first band appear on your screen.

As a goal, you should finish Part 1, Exercises 1. Surfaces — Fly through and Illumination.

GEOB Lab 3: Introduction to IDRISI

Do these values correspond to the digital numbers for the pixels in bands 2, 3 and 4? What features in particular stand out in mankal image the ‘fuzzy worms’ 5 Question From within the Raster Group, idridi Landsat 6 and Landsat You will first import the Landsat data. Note that we don’t have Band 6L or 6H data. 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.

Name seova layer to be created Cities. Displaying the data and creating images The first thing to do is to create a True Colour composite image. Since remotely sensed images are large, please do not copy any data to your H: Advanced GIS Geob Note that Exercises 1. Accept the other defaults, and click on OK. Hand in the results of your Transparency exercise.

Click on the check boxand then click on the Then, click on the Group Link button and zoom into the band 6 image; you should then also zoom into the same area in manial Landsat image. Click on Projects tab in the Idrisi Explorer window.

This will save your composition for further editing. Right click on the title Using the captionadd your name, lab and date to the composition. Since the first Output Idrisi image filename was converted to all uppercase, it idrksi be better if you retyped that filename to follow the case of the other filenames.

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