The MALÅ GPS standard, GPS format contains the following information:
trace number, date, latitude, longitude, height above mean sea level, and
HDOP. The HDOP value is a theoretical measure of the accuracy in the
horizontal coordinates based on the positions of the available GPS
satellites. A lower value indicates better accuracy. The date and time is
expressed in Greenwich Time zone. An excerpt from a data file is seen
below:
