<div>Hi all:</div>
<div> </div>
<div>I downloaded some data, but the data itself doesn’t have lat&lon arrays
except the lat&lon values for the center point and x&y in kms for the
origin point. I can calculate the approximate lat&lon arrays linearly. The
plot and my script is attached. As you can see there is blank stripes on both
sides of the plot. Does anyone know how to plot in a more correct way or how to
calcuate the acurrate lat&lon arrays?</div>
<div> </div>
<div>thanks,</div>
