Graphics and the Cursor - Contouring Data With the Cursor

In this exercise, you will contour the temperatures and brightness levels of an image.
  1. Erase the graphics in frame 1. Display the second most recent GOES-16 2km IR image on frame 1 centered on 36° N and 104° W. Magnify the resolution by a factor of 2.
    Type:  ERASE G 1;IMGDISP G16FD.-1 1 LATLON=36 104 MAG=2 BAND=13 SF=YES
  2. Position the cursor in the center of the frame. Contour the brightness levels using a contour interval of 20 inside a 401 by 401 pixel cursor.
    Type:  PC C;IMGPROBE CONT BOX BRIT SIZE=401 401 CINT=20 MODE=N

  3. Display the second most recent GOES-16 2km IR image on frame 2 centered on 36° N and 104° W. Magnify the resolution by a factor of 2.
    Type:  IMGDISP G16FD.-1 2 LATLON=36 104 MAG=2 BAND=13 SF=Y
  4. Position the cursor in the center of the frame. Contour the temperature inside a 401 by 401 pixel cursor. Specify a contour interval of 5 Kelvin.
    Type:  PC C;IMGPROBE CONT BOX TEMP SIZE=401 401 CINT=5 MODE=N
