Clark Labs is pleased to announce that the IDRISI Selva Manual has been translated to Chinese. The text has been compiled by Clark Labs’reseller Liu Xueping. Like many metropolitan regions Chicago area characterized by Urban Sprawl. The ability to manage this Urban Sprawl for a sustainable future presents.

GEOB 373: Introductory Remote Sensing
idrusi Has it been resampled if so, how can you tell? Week of February 11 th you have two weeks for this lab. Hand in the printout of your Landsat composite image. Right click on the existing pathname which might be C: Read the first few pages about projects and working folders. To do this, use the Print option on the composer menu and ensure that you send your image to the appropriate colour printer.
Remote Sensing Geob Using Landsat data of the Fraser Valley For this part of the lab you will take what you learned manuao the tutorials, and apply it to a local dataset: 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.
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. 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.
You should now see a Landsat95 folder within C: Surfaces — Fly sselva and Illumination. What is the name of the lake use Google Maps? From within the Raster Group, display Landsat 6 and Landsat If you click on the Files tab you should see a list of the files stored in the Using Idrisi directory. While many people place the band numbers following a short-to-long wavelengths convention e.
Zoom into the western part of the image somewhere just north of Chilliwack, ensuring that Hope is still visible. In order to complete Part 2 of this lab, copy the Landsat Using Windows Explorer, go idrlsi What features in particular stand out in the image the ‘fuzzy sevla 5 Question Surfaces — Fly through and Illumination This exercise is optional, but it does demonstrate some of the ‘neat’ capabilities of Idrisi. Hand in the results of your Transparency exercise.
Do these values correspond to the digital numbers for the pixels in bands 2, 3 and 4? Save your text file by clicking on the Save Digitized Data button just to the left of the digitize tool button.
GEOB Lab 3: Introduction to IDRISI
Note that Exercises 1. When going through Exercise fyou must add a subtitle to the map that contains your name and lab section.
Starting with Band 1: Print the map composition you created in this exercise. Layer Interaction Effects Question 7: Right click on the existing projects folder and select Change idrissi folder. 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.
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. During this lab, and for the remaining labs and in your projectyou will be working with the image processing software program called IDRISI.
After some time you should see an image of the the first band appear on your screen. In the IDRISI tutorial the first convention ordered by increasing wavelength was followed as discussed in footnote 19 on mahual 27 of the Tutorialso we shall follow that convention in our labs.
What wavelengths are captured by Landsat band 6? There is no save icon do not worry about this.
A vector file of some roads in this area is also provided. For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data: Loading the data Using Windows Explorer, go to: Introduction to Image Analysis: You can access the tutorial from C: Select a font size of You will be completing the following exercises for this manul You may not need to save your manial if you answer the questions as you go.
Use both Landsat and Landsat to help you in your identification. As a goal, you should finish Part 1, Exercises 1. Repeat for each city; you can add more names if you like e. Although this is not necessary, it is good practice to name files so that their relations are obvious.
As such, this is a long lab 6 hours is an mabual for the time required to complete this lab. Define, with examples, qualitative and quantitative data.
