I would like to know if it is possible to calculate the geographic coordinates (lat, lon) for a pixel specified by its x/y (top-left) cartesian coordinates in a map image/raster?
The datum and projection are known: WSG84/EPSG4326 , as the envelope/extent (4 "corners" + the center point).
It seems the goal is somewhat similar to the one of
gdallocationinfo, but I don't find the way to indicate the map extent/bbox.
If possible, tools from GDAL or GeographicLib can be used.
I can't find the related formula.
