File Information
Description

Function that convert geographic coordinates to North azimuthal equal-area map with 25 km
resolution pixel (EASE-Grid projection or NL). That projection is used mainly in remote sensing and cover the northern hemisphere.

If you want to know the corresponding pixel in the EASE-Grid projection to a location for which you have geographic coordinates. For example, if you want to know in which pixel is the North Pole in the EASE grid projection, type:

[column,row] = geo2easeGrid(90,0)

The output in MATLAB would be 361,361, which is the map origin.

The idea is good. However, variables need to be renamed. colonne --> column and ligne --> row
Also watch the the column and row origin with images other than 721*721.
