Hello scotchegg,alpilotx. I am author of Japan-HD. Because I am not good at English, please forgive my strange English... scotchegg,Thank you for introduce my scenery. alpilotx...New Zealand pro???It is a great hounour to meet you. I will answer the question. OSM is good.Forests missing is that I do not know well how to use the XP2OSM. Object contains forest with a certain size is not converted.Why? Elevationdata is here.It provides DEM(5m,10m,250m mesh) and vector data.I converted provided DEM file to Bil file by my original program. Then,I converted Bil file to dsf file by meshtool2.1. Xes-file was default. So,my scenery is X-plane9.X style(It can be used in X-plane10 too). Thank you.
