Hi Carolyn
oops. forgot something ... see upper left coords ...
This looks to me exactly like a "tfw"-file, just on a row instead of multiple rows; as
follows:
1.0 = Pixel Size x in coord units
0.0 = not used (as far as I know it's for rotation, but I never have seen it othre
than 0)
0.0 = not used (")
-1.0 = Pixel Size y in coord units
398329.5 = X-Upper left coord in coord units (center of Pixel)
4435673.5 = Y-Upper left coord in coord units (center of Pixel)
regards
Flavio
