The first thing to do is to create a True Colour composite image. Under Display, select Composite. One of the first steps you must complete before starting most Digital Image Analysis DIA projects is to import the data i. To do this, use the Print option on the composer menu and ensure that you send your image to the appropriate colour printer. You will then import some Landsat data tutrial the Fraser Valley and answer some questions pertaining to that dataset.
GEOB 373: Introductory Remote Sensing
Scientific Research An Academic Publisher. What is the name of the lake use Google Maps? Studying land use dynamics of these forest reserves is essential for analysing various ecological and developmental consequences over time.
The Group Linked Zoom instructions in Exercise provide more details, if necessary. Click in the image window where you want the beginning of the text to go.
Room Office hours: Select Text as the Layer Type. Double-click on the zip file Landsat To check that the two import processes worked as expected: Why is it used i. For this lab, and the succeeding labs, you will be tuyorial Windows Explorer to copy, paste, unzip and zip the data: Apply the tools and concepts you learned in the tutorials to a dataset specific to the lab.
What is the elevation of the lake?
GEOB Lab 3: Introduction to IDRISI
Do not save the zip file to H: Displaying the data and creating images The first thing to do is to create a True Colour composite image. Print your band 6 image. Layers and Group files Question 4. The naming convention for composite images is variable. Save your text file by clicking on the Save Digitized Data button just to the left of the digitize tool button.
You have now set both the projects folder and the working directory. Add the vector layer roads as above recall: When going through Exercise fyou must add a subtitle to the map that contains your name and lab section. Navigation Map Query Question 9: Ensure that the output file names are spelled the same, but end with the appropriate band. What features in particular stand out in the image the ‘fuzzy worms’ 5 Question Accept the other defaults, and click on OK.
Accept the defaults for Contrast stretch type and Output type, but check the box beside Omit zeros What information is being presented in this band’s image, and how could it be used? Right click on the title Using the captionadd your name, lab and date to the composition.
Define, with examples, qualitative and quantitative data. Loading the data Using Windows Explorer, go to: Use both Landsat and Landsat to help you in your identification.
Specify the rotation angle for the text the default Rotation Angle of Select a font size of There is the need for participation of different stakeholders and sectors idrisii solve conflicting demands on limited forest resources and ensure ecosystem integrity.
The roads should appear overlaid on the Landsat image. Surfaces — Fly through and Illumination.
You can determine this from the Feature Properties box. 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. Introduction to Image Analysis: However, remember that with this experience you can put down in your resume that you have some working knowledge of image processing. You will first import the Landsat data. During this lab, and for the remaining labs and in tutorjal projectyou will be working with the image processing software program called IDRISI.
Given the length of this lab, you should budget your time accordingly. Read the first few pages about projects and working folders.
Prediction of scenario carried out using neural network, which is a built-in module in the Idrisi. Name the layer to be created Cities.
