[ncl-talk] problem for map plotting data without explicit coordinate arrays

[Lijun Diao]

Hi all:

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?

thanks,
