Arashim There is the need for participation of different stakeholders and sectors to solve conflicting demands on limited forest resources and ensure ecosystem integrity. 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:. Given the length of this lab, you should budget your time accordingly.

Kadal Rapid population growth and increasing economic activities have resulted in selv exploitation and rapid decline in the spatial extent of forest reserves in Nigeria. As a goal, you should finish Part 1, Exercises 1. Apply the tools and concepts you learned in the tutorials to a dataset specific to the lab. Repeat for each city; you can add more names if you like e. The goal of this lab is to give you the foundations for working with IDRISI, the image processing program that you will icrisi using in all of your subsequent labs, and for your final project.
What does NDVI stand for? However, remember that with this experience you can put down in your resume that you have some working knowledge of image processing. 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 crops.
Remember tutroial when you use the computers in the lab, you should work locally on the C: In the IDRISI tutorial the ivrisi convention ordered by increasing wavelength was followed as discussed in footnote 19 on page 27 of the Tutorialso we shall follow that convention in our labs. A vector file of some roads in this area is also provided. The dichotomy that faces nursing tutorial staff.
Zoom into the area just southeast of Chilliwack where Tuhorial 1 runs more or less due east-west, and use the Measure tool to determine how far off in a north-south direction only the vector roads are from the roads as imaged idrisk the Landsat images. Studying land use dynamics of these forest reserves is essential for analysing various ecological and developmental consequences over time. Displaying the data and creating images The first thing to do is to create a True Colour composite image.
To create a true colour composite of bands 1, 2 and 3: How far west from Madrid is the lake in the top of the image? Accept the other defaults, and click on OK. The naming convention for composite images is variable. Define, with examples, qualitative and quantitative data. Click on Projects tab in the Idrisi Explorer window.
To do this, you need to display band1 in blue, band2 in green and band3 in red. Surfaces — Fly through and Illumination This exercise is optional, but it does demonstrate some of the tutoial capabilities of Idrisi.
What is the elevation of the lake? Repeat this process for the 6 remaining bands. Prediction of scenario carried out using neural network, which is a built-in module in the Idrisi.
Why is it used i. Set the map scale RF toomitting hutorial comma when specifying the scale; right-mouse clicking within the image allows you to specify the map scale. There is the need for participation of different stakeholders and sectors to solve conflicting demands on limited forest resources and ensure ecosystem integrity. You can access the tutorial from C: The Group Linked Zoom instructions in Exercise provide more details, if necessary.
Right click on the title Using the captionadd your name, lab and date to iidrisi composition. Include the same information as in the previous map, but provide an appropriate title.
Do not save the zip file to H: Since the first Output Idrisi image filename was converted to all uppercase, it would be better if you retyped that filename to follow the case of the other filenames.

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. As such, this is a long lab 6 hours is an estimate for the time required to complete this lab. However, remember that with this experience you can put down in your resume that you have some working knowledge of image processing. Given the length of this lab, you should budget your time accordingly. As a goal, you should finish Part 1, Exercises 1. In the second week, complete the rest of Part 1, Exercises 1.
