Name the layer to be created Cities. Click on Projects tab in the Idrisi Explorer window. You will first import the Landsat data.
GEOB Lab 3: Introduction to IDRISI
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. Remote Sensing Geob Ensure that the output file names are spelled the same, but end with the appropriate band. What wavelengths do each band capture, and what feature characteristics does each band, in particular, highlight?
What is the formula i.
Note that we don’t have Band 6L or 6H data. What is the name of the lake use Google Maps?
Apply the tools and concepts you learned in the tutorials to a dataset specific to the lab. Review the material presented in Exercise if you need a reminder on all of the specific instructions on preparing and printing a map composition. Zoom into the area just southeast of Chilliwack where Hwy 1 runs more or less due east-west, and use the Measure tool to determine how far off in iddisi north-south direction only the vector roads are from the roads as imaged in the Landsat images.
Note that the San Francisco data Just for Fun Click on the check boxand then click on the You will then import some Landsat data of the Fraser Valley and answer some questions pertaining to that dataset. Hand in the results of your Transparency exercise.
Remember that when you use the computers in the lab, you should work locally on the C: Right click on the existing pathname which might be C: Supervised Image Classification and Lab 6: You can determine this from the Feature Properties box. The data for the labs should be loaded into C: Use idriwi Landsat and Landsat to help you in your identification.
What is ordinal, or ranked, data? Using Windows Explorer, go to: What does NDVI stand for? You will be complete five of the Tutorial Part 1: Note that Exercises 1. Home Syllabus Schedule Projects. REF The Landsat images have been georeferenced to a UTM [zone 10, North] coordinate system, so if we assign the same georeference system selvw 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.
Is the spatial resolution of this image different from that of the other bands? During this lab, and for the remaining labs and in your projectyou will be working with msnual image processing software program called IDRISI. You have now set both the projects folder and the working directory.
Name the output file Landsat Repeat this process for the 6 remaining bands. Advanced GIS Geob What features turned ‘black’ in the image after adjusting the contrast?
Right click on the existing projects folder and select Change projects folder. Zoom into the western part of the image somewhere just north of Chilliwack, ensuring that Hope is still visible. You should now see a Landsat95 folder within C: Layers and Group files Question 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 3D view and fly through optional, but fun.

Add the three imagebands band1 as blue, band2 as green, and band3 as red. Describe the strengths of each of the three images Landsat, Landsat, band 6 idisi have explored above, in aiding you with respect to interpreting the landscape. The differences between raster and vector data are discussed throughout the exercises, aelva Exercises and in particular cover the material you should use in your answer to this question. What wavelengths are captured by Landsat band 6?
Read the first few pages about projects and working folders. Use Google Earth and Google Maps link to the map to familiarize yourself with the area.
