GEOB Lab 3: Introduction to IDRISI

Rapid population growth and increasing economic activities have resulted in unsustainable exploitation and rapid decline in the spatial extent of forest reserves in Nigeria. In the second week, complete the rest of Part 1, Exercises 1. kdrisi

From within the Raster Group, display Landsat 6 and Landsat Do these values correspond to the digital numbers for the pixels in bands 2, 3 and 4? During this lab, and for the remaining labs and in your projectyou will be working with the image processing software program called IDRISI. Supervised Image Classification and Lab 6: Room Office hours: Select Text as the Layer Type. Print your band 6 image.

Remote Sensing Geob 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. The first thing to do is to create a True Colour composite image.

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?


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 way for cultivation of tuttorial. This should give idrisj a false colour near IR composite of the Fraser Valley. Given the length of this lab, you should budget your time accordingly.
