# this program reads AI ground networks from X-Plane/WED apt.dat file
# adds index numbers to the parking positiouns (0...n) and renumbers the
# taxinodes (n+1...m)
# adds one additional taxi node per parking position for a straight line pushback
# and 2 TaxiwaySegments(arc) that connect the parking to the new node and the new node
# to the nearest node of the groundnet(bestnode_id).
# both of those TaxiwaySegments are bi-directional and marked as "pushBackRoute"
# bestnode_id is maked as holdPointType = "PushBack"
# the parking gets a pushBackRoute= entry that is bestnode_id
#
# the result is written into a sqlite DB "groundnets.de"
# which can be read by the tool sqlite2xml.py
#this script runs 3 minutes on a
#Intel Core2 Duo CPU P8600 @ 2.40GHz
