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. In completing ttuorial and the next three labs Lab 3: While many people place the band numbers following a short-to-long wavelengths convention e.
Under Display, select Composite. Note that we don’t have Band 6L or 6H data. Select the caption position relative to the anchor point e. Browse for the Roads file it should be the only choice.
Specify the rotation angle for the text the default Rotation Angle of However, remember that with this experience you can put down in your resume that you have some working knowledge of image processing. Click on Projects tab in the Idrisi Explorer window. Tope-AjayiOlukemi L.
Note that this term differs from orthophoto. Note that the San Francisco data Just for Fun Scientific Research An Academic Publisher.
The data for the labs should be loaded into C: Note that Exercises 1.
For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data:. Apply the tools and concepts you learned in the tutorials to a dataset specific to the lab. The imageries were classified using ArcGIS This dataset is from Spain. Do not save the zip file to H: As such, this is a long lab 6 hours is an estimate for the time required to complete this lab.
After some time you should irrisi an image of the the first band appear on your screen. Using Windows Explorer, go to: Select a font size of To check that the two import processes worked as expected: View the online tutorial.
Read the first few pages about projects and working folders.
There is no save icon do not worry about this. Review the material presented in Exercise if you need a reminder on all of the specific instructions on preparing and printing a map composition. Although this is not necessary, it is good practice to name files so that their relations are obvious. Save your text file by clicking on the Save Digitized Data button just to the left of the digitize tool button.

What does NDVI stand for? Click on Map Properties Add a north arrow and a scale bar.
The study concluded that increasing loss of the indigenous forest and plantation would continue thus having implications for biodiversity conservation in the study area. Print the map composition you created in this exercise. Click on the check boxand then click on the
