Dear all,

is there anywhere some library around, which handles georeferenced
grids. I mean a structure like e.g.

grid = { upperLeftX: float, upperLeftY: float, pixelSize: float,
image: bytarr(rows,cols,channels) }

with methods for extracting subimages according to geolocation,
displaying and mouse-point information etc. I know it is not so
difficult to implement this, but re-inventing the wheel is not very
useful.
(By the way ENVI must have such objects, but I do not know how access
them, and how they are exactly defined).

Thanks very much,
Markus Reichstein
