I have a map file with following MapExtent parameter:
EXTENT 106.335006 -6.896956 107.315811 -5.983994

in the case of an unrotated mapsheet.
The fourth row is the y-pixel resolution (dimension in coordiantes). The
Thanks, folks. But how do I know my x-pixel resolution? And y-pixel resolution?
Can it be derived from EXTENT parameters?
Thanks again,
