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 3D view and fly through optional, but fun.
During this lab, and for the remaining labs and in your projectyou will be working with the image processing software program called IDRISI. Hand in the printout of your Landsat image composition.
Surfaces — Fly through and Illumination. Studying land use dynamics of these forest reserves is essential for analysing various ecological and developmental consequences over time.
Ensure that the output file names are spelled the same, but end with the appropriate band. Layer Interaction Effects 1. When going through Exercise fyou must add a subtitle to the map that contains your name and lab section.
Define, with examples, qualitative and quantitative data. As a goal, you should finish Part 1, Exercises 1. Click on the check boxand then click on the While many people place the band numbers following a short-to-long wavelengths convention e. What wavelengths do bands 5 and 7 capture, and what feature characteristics do they, in particular, highlight?
GEOB Lab 3: Introduction to IDRISI
What information is being presented in this band’s image, and how could it be used? In the IDRISI tutorial the first convention ordered by increasing wavelength was followed as discussed in footnote 19 on page 27 of the Tutoroalso we shall follow that convention in our labs. Tope-AjayiOlukemi L.
For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data: Layers and Group files Question 4. Select the caption position relative to the anchor point e.
Since remotely sensed images are sela, please do not copy any isrisi to your H: What features turned ‘black’ in the image after adjusting the contrast? Prediction of scenario carried out using neural network, which is a built-in module in the Idrisi.
What is the elevation of the lake? Note that this term differs from orthophoto. What is ordinal, or ranked, data? How far west from Madrid is the lake in the top of the image? Double-click on the zip file Landsat Remember that when you use the computers in the lab, you should work locally on the C: 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.
Although this is not necessary, it sevla good practice to name files so that their relations are obvious. 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. You will be completing the following exercises for this lab: Click tutoria Projects tab in the Idrisi Explorer window.
A vector file of some tutoriak in this area is also provided.
GEOB 373: Introductory Remote Sensing
Surfaces — Fly through and Illumination This exercise is optional, but it does demonstrate some of the ‘neat’ capabilities of Idrisi. 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? Navigation Map Query Question 9: You will then import some Landsat data of the Fraser Valley and answer some questions pertaining to that dataset. The study revealed dramatic decline in the extent of the forest reserve as both the plantation of exotic tree species Tectona grandis and Gmelina and the indigenous stands have been logged in several places for timber and to make thtorial for cultivation of crops.
Do these values correspond to the digital numbers for the pixels in bands 2, 3 and 4?
