where:
LONGITUDE The real number describing the longitude encoded as a
printable string. The precision is limited by 256 charcters
within the range -90..90 degrees. Positive numbers
indicate locations north of the equator.
LATITUDE The real number describing the latitude encoded as a
printable string. The precision is limited by 256 charcters
within the range -180..180 degrees. Positive numbers
indicate locations east of the prime meridian.
ALTITUDE The real number describing the altitude (in meters) from
mean sea-level encoded as a printable string. The precision
is limited by 256 charcters. Positive numbers indicate
locations above mean sea-level.
Latitude/Longitude/Altitude values are encoded as strings as to avoid
the precision limitations imposed by encoding as unsigned integers.
Although this might not be considered optimal, it allows for a very
high degree of precision with an acceptable average encoded record
length.
