# Simple script to convert GPX logs to OpenSteetMap for easy importation.
# Sets some basic defaults to speed up the process a bit.

# If you are really careless you can describe HDOP as a multiplier to the
# intrinsic error of the full hardware chain, typically 5 to 8 metres.
# So, again, very careless, HDOP of 10 means an uncertainty of 50 to 80 metres.
