Congratulations on the Sydney model developments. Will this become available for download soon?
I liked your image so much that a couple of days ago I went and added Lanzarote scenery and height maps in FS2 just to recreate your screenshot scene. Well done. I didn't even know that volcanic island existed.
i have forgotten how to do height maps for Australia con someone please link me to the instructions?
Using this site, I draw a box around the area I need better height maps for and then select the box next to the "1 Second Digital Elevation Model" to then download it*. It emails you a ZIP file that contains the ready-made GeoTiff file and also contains the co-ordinates that you need to use when editing the .TFW and .TMC files. Refer Qwerty42's good video instructions contained in his post for how best to edit and then relocate these files ready for processing into heightmaps by the Aerofly FS2 Geoconvert tool.
*I found that while 1 metre Digital Elevations Models available on the http://elevation.fsdf.org.au site are higher quality and much larger files, the resulting GeoTIFF file often has missing large sections of data in your selected area. Missing data results in big visual corruptions in the converted tiles within Aerofly FS2 so you need consistent coverage. I find 1 Second files generally cover the entire drawn area selected and work a lot better within Aerofly FS2 as the height map tiles are complete and consistent. So give 1 Metre models a go to obtain best quality, but if the TIFF file you load is only partially complete, go with the 1 Second models, which are less detailed but generally deliver a more consistent result.
As suggestions, these new user-generated height maps really improve mountainous areas like the Glass House Mountains in Queensland, Blue Mountains in Katoomba, Uluru, and the whole Illawarra escarpment. I've now posted some screenshots using my user-made Australian height maps in Aerofly FS2 in the gallery.
