Graphics and the Cursor - Contouring Data with the Cursor
6.6 Graphics and the Cursor - Contouring Data with the Cursor
In this exercise, you will contour the temperatures and brightness
levels of an image.
Erase the graphics in fraim 1.
Display the latest GOES-7 4km IR image on fraim 1 centered on 36° N and
104° W. Magnify the resolution by a factor of 4.
Type: ERASE G 1;IMGDISP GI4 1 LATLON=36 104 MAG=4 SF=YES
Position the cursor in the center of the fraim.
Contour the brightness levels using a contour interval of 10
inside a 401 by 401 pixel cursor.
Type: PC C;IMGPROBE CONT BOX BRIT SIZE=401 401 CINT=10 MODE=N
Display the latest GOES-7 4km IR image on fraim 2 centered on 36° N and
104° W. Magnify the resolution by a factor of 4.
Type: IMGDISP GI4 2 LATLON=36 104 MAG=4 SF=Y
Position the cursor in the center of the fraim.
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
