<div dir="ltr"><div><div><div>Hello,<br></div> I have height data on a two
dimensional equidistant latitude longitude grid and my ultimate goal is
to calculate the curvature of the contours. Here is an illustration of
what I want to do - <a href="http://www.indiana.edu/%7Egeog109/topics/10_Forces&Winds/sfc_trough.html" target="_blank">http://www.indiana.edu/%<wbr>7Egeog109/topics/10_Forces&<wbr>Winds/sfc_trough.html</a>.
The data is plotted on a two dimensional latitude longitude grid and
then the height contours are calculated. I am looking to obtain the
coordinates of the contours(shown in red) in terms of latitude and
longitude so that I can use that information to calculate the curvature
of the contour points using a least squares method. Is it possible to
do this in Scipy ? The curvature of the earth is itself irrelevant in
this case and it can be assumed to be flat. <br><br></div>Regards,<br></div>Ashwin. </div>
