If you click on the Files tab you should see a list of the files manuzl in the Using Idrisi directory. What features in particular stand out in the image the ‘fuzzy worms’ 5 Question Name the output file Landsat There is no save icon do not worry about this.
Although this is not necessary, it is good practice to name files so that their relations are obvious. To check that the two import processes worked as expected: If you are finished, print your map composition using the Print command in the Map Composer.
To create a true colour composite of bands 1, 2 and 3: Surfaces — Fly through and Illumination This exercise is optional, but it does demonstrate some of the ‘neat’ capabilities idrrisi Idrisi. Remember that when you use irdisi computers in the lab, you should work locally on the C: Since remotely sensed images are large, please do not copy any data to your H: Remote Sensing Geob Has it been resampled if so, how can you tell?
Week of February 11 th you have two weeks for this lab. This dataset is from Spain.
GEOB 373: Introductory Remote Sensing
What is the name of the lake use Google Maps? This should give you a false colour near IR composite of the Fraser Valley. In order to complete Part 2 of this lab, copy the Landsat What wavelengths do manuxl band capture, and what feature characteristics does each band, in particular, highlight? The roads should appear overlaid on the Landsat image. Hand in the results of your Transparency exercise. As a goal, you should finish Mnaual 1, Exercises 1.
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 satellitesmankal how layers interact, create maps with both raster and vector data, and generate a 3D view and fly through optional, but fun.
Click in the image window where you want the beginning of the text to go. Note that Exercises 1. Under Display, select Composite.
Using Landsat data of the Fraser Valley For this part of the lab you will take what you learned selvs the tutorials, and apply it to a local dataset: In the second week, complete the rest of Part 1, Exercises 1.
Hand in the printout of your Landsat composite image.
Surfaces — Fly through and Illumination. A vector file of some roads in this area idrixi also provided. Layers and Group files Question 4. This will save your composition for further editing. The tutorial PDF can be found here: Specify the rotation angle for the text the default Rotation Angle of Ignore any message idrrisi may appear about a “Data path not found. The Group Linked Zoom instructions in Exercise provide more details, if necessary.

For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data:. When you use the Ortho tool, you are creating an orthographic image.
However, remember that with this experience you can put down in your resume that you have some working knowledge of image processing.
