Do these values correspond to the digital numbers for the pixels in bands 2, 3 and 4? What features turned ‘black’ in the image after adjusting the contrast? After some time you should see an image of the the first band appear on your screen. Review the material presented in Exercise if you need a reminder on all of the specific instructions on preparing and printing a map composition. Accept the other defaults, and click on OK.
Do not save the zip file to H: Print your band 6 image.
Select the caption position relative to the anchor point e. Navigation Map Query Question 9: Week of February 11 th you have two weeks for this lab. The naming convention for composite images is variable.

Note that this term differs from orthophoto. What wavelengths do bands 5 and 7 capture, and what feature characteristics do they, in particular, highlight? Tqiga Syllabus Schedule Projects. 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.
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. Another window will appear, in which you enter the name of the city Caption. Under Display, select Composite.
GEOB Lab 3: Introduction to IDRISI
Remember that when you use the computers in tutoril lab, you should work locally on the C: The Group Linked Zoom instructions in Exercise provide more details, if necessary. If you click on the Files tab you should see a list of the files stored in the Using Idrisi directory.
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? Repeat for each city; you can add more names if you like e.

This dataset is from Spain. Remote Sensing Geob Surfaces — Fly through and Illumination This exercise is optional, but it does demonstrate some of the ‘neat’ capabilities of Idrisi.
Although this is not necessary, it is good practice to name files so that their relations are obvious.
To create a true colour composite of bands 1, 2 and 3:
