Re: [Flightgear-devel] svg2ac

Well we have an SVG parser that reads the input svg file and extract the polygons for the keywords buildings, runways & taxiways. The vertices are then stored and duplicated to create the "roof". The side polygons are computed by duplicating again 2 consecutive nodes that form an edge.
The altitude is fetched from a running session of FlightGear via telnet for the location of the center of each building.
All the coordinates are then converted to meters using the 4 Lat/Long lines present in the SVG file and then the Lat/Long coordinates of the origin is obtained, this is needed in the .stg file.
That's pretty much it. I recently tried a new airport (Toronto, CYYZ) given by Ampere, it looked pretty good besides the two problems presented in the previous email.
