# This file is designed to convert tree data from a 
# csv format (at opentrees.org) to a geojson format.
# This version uses compact versions of the standard geojson keys,
# to make transferring over the network more efficient.
#
# This effort is part of the earthtree ios swift app which is 
# designed to display and map trees in the entire world! one by one!
