Use Xastir's coordinate calculator to convert from DDMM.MM format to
DD.DDDD format.  W and S coordinates are negative.

WEST BOUNDING COORDINATE:  -121.000000   (121.0W)
EAST BOUNDING COORDINATE:  -120.000000   (120.0W)
NORTH BOUNDING COORDINATE:  48.500000    (48.5N)
SOUTH BOUNDING COORDINATE:  48.000000    (48.0N)
