Now, I look for a function/procedure in NCL (or maybe in R or Python, if those are better suited) that can tell me all the points that are part of a region given that at the beginning of the algorithm I provide one gridpoint that should be member as well.<br>
<br>
The closure or border of my region is defined by all the gridpoints that are FillValue or Missing and direct neighbours of the points valid values. On the total map there might be several such separated regions, so it is important to know if that I only get the indices of the region that belongs to my initial given grid point.<br>
<br>
Is there anything coded like this in NCL (or R or Python) already?<br>
