# Geographic map bounding box. 
#
# The two GeoPoints denote diagonally opposite corners of the box.
#
# If min_pt.latitude is NaN, the bounding box is "global", matching
# any valid latitude, longitude and altitude.
#
# If min_pt.altitude is NaN, the bounding box is two-dimensional and
# matches any altitude within the specified latitude and longitude
# range.

GeoPoint min_pt         # lowest and most Southwestern corner
GeoPoint max_pt         # highest and most Northeastern corner
