Right click on the title Using the captionadd your name, lab and date to the composition. You can access the tutorial from C: As a goal, you should finish Part 1, Exercises 1. Introduction to Image Analysis: We will have some hard copies of the relevant sections of the IDRISI tutirial available for you in the lab a scanned copy of the relevant sections here.
Print your band 6 image. REF The Landsat images have been georeferenced to a UTM [zone idriisi, North] coordinate system, so if we assign the 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. While many people place the band numbers following a short-to-long wavelengths convention e.
What features in particular stand out in the image the ‘fuzzy worms’ 5.
GEOB 373: Introductory Remote Sensing
Accept the other defaults, and click on OK. 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. Click in the image window where you want the beginning of the text to go. Layers and Group files Question 4.
Hand in the printout of your Landsat image composition. Click on the check tutroialand then click on the This will save your composition for further editing. Set the map scale RF toomitting the comma when specifying the scale; right-mouse clicking within the image allows you to specify the map scale.
Add the three imagebands futorial as blue, band2 as green, and band3 as red. How far west from Madrid is the lake in the top of the image? Select a font size of Repeat this process for the 6 remaining bands. Double-click on the zip file Landsat What is the formula i.
Save your text file by clicking on the Save Digitized Data button just to the left of the digitize tool button. This dataset is from Spain.
Do these values correspond to the digital numbers for the pixels in bands 2, idrsi and 4? 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 with both raster and vector data, and generate a ixrisi view and fly through optional, but fun.
GEOB Lab 3: Introduction to IDRISI
Given the length of this lab, you should budget your time accordingly. You will then import some Landsat data of the Fraser Taiiga and answer some questions pertaining to that dataset.
Using Landsat data of the Fraser Valley For this part of the lab you will take what you learned in the tutorials, and apply it to a local dataset: Name the layer to be created Cities. Remember that when you use the computers in the lab, you should work locally on the C: 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.
Since the first Output Idrisi image filename was converted to all uppercase, it would be better if you retyped that filename to follow the case of the other filenames. During this lab, and for the remaining labs and in your projectyou will be working with the image processing software program called IDRISI. If you click on the Files tab you should see a list of the files stored in the Using Idrisi directory. Is the spatial resolution of this image different from that of the other bands?
Use the shape of the lake to help identify the specific lake [it is actually a reservoir–could you deduce this from the satellite image?
When going through Exercise fyou must add a subtitle to the map that contains your name and lab section. 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, tugorial for your final project. Surfaces — Fly through and Illumination. Starting with Band 1: When you use the Ortho tool, you are creating an orthographic image.
Since remotely sensed images are large, please do not copy any data to your H: You can determine this from the Feature Properties box. Advanced GIS Geob What features turned ‘black’ in the image after adjusting the contrast?
