Claim Text:
1. A method for generation of a surface movement network, the method comprising the steps of: receiving, from an aerodrome mapping database, a travel path comprising a taxiway; receiving, from the aerodrome mapping database, a directionality of the travel path; representing the taxiway with a set of polygons; dividing each polygon in the set of polygons into a plurality of segments, each segment having a midpoint, wherein, for each polygon, the plurality of respective midpoints are substantially aligned with the directionality of the travel path; creating, for each polygon of the set of polygons, a centerline with substantially the same directionality as the travel path by connecting midpoints; generating a taxiway centerline using the polygon centerlines; receiving, from an aerodrome mapping database, a travel path comprising a runway; obtaining runway threshold points associated with the runway, wherein the runway threshold points are defined as centerline points on runway thresholds; and creating a runway centerline for the runway using the runway threshold points.
