In this exercise, you will create loop bounds, and display a loop of images.

Creating Loop Bounds

1. Bring up the Loop Bounds GUI under the Configure menu.

   Select: Configure/Loop Bounds

2. Start a new loop.

   Click: New Loop

3. Select your loop bounds by clicking on the first frame, and dragging the mouse over the desired frames to be included in the loop bounds.

   Select: Frames 1 through 3

4. Rename 'Loop 1' to 'Satellites.'

   In the Loop Name field, change 'Loop 1' to 'Satellites'.

5. Save the Loop.

   Click: Set Loop

6. Dismiss the Loop GUI.

   Click: Dismiss

Next, you will display the 3 latest GOES-West, band 1 images in the 'Satellites' loop.
1. Use the Image Select GUI to choose the three most recent GOES-West CONUS satellite images.

   Select: Display/Image

   Select: Dataset/WEST/CONUS

   Select 3 images by clicking on the first and dragging the mouse button over the rest.

2. Start the loop on frame 1, display a map on each image, select the geographical coverage of the images, and display the loop.

   Select: Select Frame/Satellites/1

   Click: Display Map on Image

   Click: Location

   Use the mouse to select a new data coverage area.

   Click: Load and Dismiss

   This will load all selected images and dismiss the GUI when the loading process is complete.

3. Start the looping of the images.

   Click: Play

   Notice how the looping follows the 'Satellite' loop bounds and only loops the first three frames. You may change the loop speed by sliding the Loop Speed slider or clicking on the plus and minus buttons. Moving the slider to the right decreases the dwell rate, thus increasing the looping speed. Moving the slider to the left decreases the looping speed.

4. Make the loop pause on the most recent image.

   Click: Pause on Latest Image

   Notice how the loop now pauses longer on frame number 3 than it does on frames 1 and 2.

5. Stop the looping.

   Click: Stop

Next, you will create a NEXRAD loop and display a loop of real-time NEXRAD images from a station that you select.
1. Create a new loop called 'NEXRAD'.

   Select: Configure/Loop Bounds

   Click: New Loop

   Select all six frames, by clicking frame 1 and dragging the mouse down to frame 6

   Rename 'Loop2' to 'NEXRAD'

   Click: Set Loop

   Click: Dismiss

2. Display a loop of NEXRAD images

   Select: Display/Image

   Select: Select Frame/NEXRAD/1

   Select: Dataset/RTNEXRAD/N0R

   Click: State

   Click: the state of your choice

   Click: Station

   Click: the station of your choice

   Select the six most recent images by clicking the first image and dragging the mouse down over the next five images.

   Click: Load and Dismiss

3. Start the looping of the images.

   Click: Play

4. Stop the looping.

   Click: Stop

5. When you are done viewing the NEXRAD loop, erase the images and graphics from the current frame.

   Click: Erase Image

   Click: Erase Graphics
