Downloading Images from DNGP Exercise 3 - Downloading Image-Derived Products from DNGP Objective: View and download NDVI products from DNGP for the newly created AOI. Task1: Download a color NDVI image from DNGP 1. Log in to DNGP as demonstrated in Exercise 1. 2. Select the new AOI created in Exercise 2. 3. Display an image with full coverage of the AOI as demonstrated in Exercise 1. 4. Click to display the NDVI for the selected image.  5. Click download to save the NDVI image to your hard disk. Note the name of the saved file. It should be in the format: colorNDVI_1107108618_3027_072604.tif. This file name is similar to that of the Landsat image, except instead of allbands, the name has colorNDVI at the beginning. Task 2: Download a grayscale NDVI image from DNGP. 1. Click to display a grayscale NDVI image in the viewer. 2. Click download to save the grayscale NDVI image to your hard disk. 3. Note the name of the saved file. We are currently modifying the default names of these files, so if the name does not begin with grayNDVI please change it so that it does - this will make the file easier to identify later. Your saved file should have a name in this format: grayNDVI_1107109836_3027_072604.tif.  Task 3: Repeat Tasks 1 and 2 to download color and grayscale versions of the "green NDVI" product from DNGP.
