I whould like to kwon if it’s possible with SNAP to convert a layer/mask (or more specifically a edge) into a set of points ?
How could I know the passage between X/Y and lat/long ? (with some tie-grid points I guess)
Is it a bijection (ie X/Y → lat/long and lat/long → X/Y) ?
My goal is to create some polygons (using WKT) in order to select some areas which does not contain many clouds.
Once I have a polygon, is it possible to define the area inside and outside this polygon in order to get the areas with and without clouds ?
And if I want to select the area outside of the polygon, what command should I write in the Band Maths operator ?
Furthermore, I would like to know if I can easily convert an edge into dots in order to create some polygons which will alow me to select the area inside/outside of this polygon ?
