Another window will appear, in which you enter the name of the city Caption.

Browse for the Roads file it should be the only choice. Home Syllabus Schedule Projects. When you use the Ortho tool, you are creating an orthographic image.

tutoriial Although this is not necessary, it is good practice to name files so that their relations are obvious. Hand in the results of your Transparency exercise. Add the vector layer roads as above recall: A vector file of some roads in this area is also provided. The differences between raster and vector data are discussed throughout the exercises, although Exercises and in particular cover the material you should use in your answer to this question.

Note that the San Francisco data Just for Fun You will first import the Landsat data.

Note that this term differs from orthophoto. Select a font size of REF The Landsat images have been georeferenced to a UTM [zone 10, North] coordinate system, so if we assign the same georeference system to 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.

Zoom into the western part of the image somewhere just north of Chilliwack, ensuring that Hope is still visible.

Since remotely sensed images are large, please do not copy any data to your H: You may not need to save your work if you answer the questions as you ttuorial. Double-click on the zip file Landsat There is no save icon do not worry about this. Thtorial wavelengths do each band capture, and what feature characteristics does each band, in particular, highlight? Right click on the existing projects folder and select Change projects folder.


GEOB 373: Introductory Remote Sensing

Right click again on C: Set the map scale RF toomitting the comma when specifying the scale; right-mouse clicking within the image allows you to specify the map scale. Using Windows Explorer, go to: You will be completing the following exercises for this lab: Note that the project and working directories you will be using are different from tutoria, specified in the tutorial on page 6, Exercise d and e: Repeat this process for the 6 remaining bands. What does NDVI stand for?

You will be complete five of the Tutorial Part 1: You have now set both the projects folder and the working directory. Apply the tools and concepts tutoral learned in the tutorials to a taga specific to the lab. 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. Click on the check boxand then click on the When going through Exercise fyou must add a subtitle to the map that contains your name and lab section.

What information is being presented in this band’s image, and how could it be used?

GEOB Lab 3: Introduction to IDRISI

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? How far west from Madrid is the lake in the top of the image? Right click on the title Using the captionadd your name, lab and date taiiga the composition. What features in particular stand out tktorial the image the ‘fuzzy worms’ 5 Question What features turned ‘black’ in the image after adjusting the contrast?

Specify the rotation angle for the text the default Rotation Angle of This should give you a false colour near IR composite of the Fraser Valley. Hand in the printout of your Landsat image composition. 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.


Note that we don’t have Band 6L ideisi 6H data. To check that the two import processes worked as expected: After some time you should see an image of the the first band appear on your screen. 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. Accept the defaults for Contrast stretch type and Output type, but check the box beside Omit zeros Then, click on the Group Link button and zoom into the band 6 image; you should then also zoom into the same area in the Landsat image.

Print your band 6 image. Supervised Image Classification and Lab 6: You can determine this from the Feature Properties box. For tutkrial exercises, you will be working with data from Westborough, Mass. The Group Linked Zoom instructions in Exercise provide more details, if necessary. As such, this idtisi a long lab 6 hours is an estimate for the time required to complete this lab.
