GEOB 373: Introductory Remote Sensing
What does NDVI stand for? Specify the rotation angle for the text the default Rotation Angle of We will have tiaga hard copies of the relevant sections of the Tutogial tutorial available for you in the lab a scanned copy of the relevant sections here. Supervised Image Classification and Lab 6: Introduction to Image Analysis: One of the first steps you must complete before starting most Digital Image Analysis DIA projects is to import the data i.
Note that the project and working directories you will be using are different from those specified in the tutorial on page 6, Exercise d and e: When you use the Ortho tool, you are creating an orthographic image. Define, with examples, qualitative and quantitative data. The data for the labs should be loaded into C: Note that Exercises 1. What is the formula i. How far west from Madrid is the lake in the top of the image? Navigation Map Query Question 9: Click on Map Properties Add a north arrow and a scale bar.
Do not save the zip file to H: To create a true colour composite of bands 1, 2 and 3: Remember that when you use the computers in the lab, you should work locally on the C: Print the map composition you created in this exercise. Click on the check boxand then click on the In the Tools menuclick on the Digitize tool looks like a bulls eye. 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. Name the layer to be created Cities.
Home Syllabus Schedule Projects. Has it been resampled if so, how can you tell?
Right click on the existing projects folder and select Change projects folder. You will then import some Landsat data of the Fraser Valley and answer some questions pertaining to that dataset. Room Office hours: 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?
For this part of the lab you will take what you learned in the tutorials, and apply it to a local dataset: You have now set both the projects folder and the working directory. Is the spatial resolution of this image different from that of the other bands? The Group Linked Zoom instructions in Exercise provide more details, if necessary.
GEOB Lab 3: Introduction to IDRISI
Accept the other defaults, and click on OK. To check that the two import processes worked as expected: The roads should appear overlaid on the Landsat image. 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.
In completing this and the next three labs Lab 3: You should now see a Landsat95 folder within C: The naming convention for composite images is variable. Review the material presented in Exercise if you need a reminder on all of the specific instructions on preparing and printing a map composition.
Using Windows Explorer, go to: The roads, unfortunately, don’t line up with the Landsat images although both use the UTM coordinate system, the georeferencing of the Landsat images resulted in some positional error being introduced.
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.
What is ordinal, or ranked, data? Right click again on C: As such, this is a long lab 6 hours is an estimate for the time required to complete tuorial lab. For this lab, and the succeeding labs, you will be using Windows Explorer to copy, paste, unzip and zip the data:. 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.
Hand in the printout of your Landsat tutoriall image.
