Zoom into the western part of the image somewhere just north of Chilliwack, ensuring that Hope is still visible. Layers and Group files Question 4. For this part of the lab you will take what you learned in the tutorials, and apply it to a local dataset: How far west from Madrid is the lake in the top of ideisi image? Specify the rotation angle for the text the default Rotation Angle of You will be completing some of the “Using IDRISI” exercises using datasets provided by IDRISI from Spain, and the US in order dirisi 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.
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 Tools menuclick on the Digitize tool looks like a bulls eye.
Since remotely sensed images are large, please do not copy any data to your H: Is the spatial resolution of this image different from that of the other bands? 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 a north-south direction only the vector roads are from the roads as imaged in the Landsat images. Use both Landsat and Landsat to help you in your identification.
AdedejiOpeyemi O. There is the need for participation of different stakeholders and sectors to solve conflicting demands on limited forest resources and ensure ecosystem integrity.
GEOB 373: Introductory Remote Sensing
The naming convention for composite images is variable. For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data: Fly through and illumination optional, but it is quick and fun!
Click in the image window where you want the beginning of the text to go. Do these values correspond to the idtisi numbers for the pixels in bands 2, 3 and 4? For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data:. What is the name of the lake use Google Maps? What features in particular stand out in the image the ‘fuzzy worms’ selav Question View the online tutorial.
Right click again on C: Click on Map Properties Add a north arrow and a scale bar.
Why is it used i. Since the first Output Idrisi image filename was converted to hutorial uppercase, it would be better if you retyped that filename to follow the case of the other filenames.
You will first import the Landsat data. Right click on the title Using the captionadd your name, lab and date to the composition. Repeat this process for the 6 remaining bands.
When you use the Ortho tool, you are creating an orthographic image. In the IDRISI tutorial the first 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. In addition, pressures from other land uses like settlements have also led to increased non-forest uses particularly bare grounds.
Use the shape of the lake to help identify the specific lake [it is actually a reservoir–could you deduce this from the satellite image? Given the length of this lab, you should budget your time accordingly.
GEOB Lab 3: Introduction to IDRISI
Select the caption position relative to the anchor point e. Ensure that the output file names are spelled the same, but end with the appropriate band. The roads should appear overlaid on the Landsat image. Include the same information as in the previous map, but provide an appropriate title. What information is being presented in this band’s image, and how could it be used?
What features in particular stand out in the image the ‘fuzzy worms’ 5. You have now set both the projects folder and the working directory.
What is the formula i. Accept the other defaults, and click on OK. Add the three imagebands band1 as blue, band2 as green, and band3 as red. However, tutrial that with this experience you can put down in your resume that you have some working knowledge of image processing.
The imageries were classified using ArcGIS Supervised Image Classification and Lab 6: Room Office hours: To do this, you need to display band1 in blue, band2 in green and band3 in red.
