[ferret_users] Re: Transformation: curvilinear to rectangular issue

[Szymon Roziewski <szymon.roziewski@xxxxxxxxx>]

And what I also did is to transform small region i.e.
x=-3.7:2.5
y=-1.5:2

And this is also improper because of some anomaly in the bottom of this picture.

Dear Ferreters,
I have interpolated some data from curvilinear coordinates into regular.
First of all I computed the array of coefficients of a transform and then I did transform.
But what I got as a result somehow embarrassed me because on the left bottom side picture I have a blurred data and I don't know why.
I attach two pictures.
The first one that I called INPUT_etopo2 is an input of the transform on curvilinear grid.
The second is a print of interpolated data onto rectangular grid but with a blur.
The region which I concentrated on was
X=-5.7:5.5
Y=-2.5:10:0
What has caused this smear? What do you think?

Kind regards,
Szymon Roziewski
