Hello
There is new data based on 1 sec ~30m spaced spot heights ..though its not available in a format directly useable by Ozi3d but can be converted if you have suitabel program for the job (eg GlobalMapper). 1 sec data can be downloaded from here (needs registration)..
ASTER GDEM
You will end up with a geotiff file with embedded DEM data. This needs tobe convertedto soem sort of ascii format for Ozi to use.
Discussion about it here
GPS Australia DEM data thread
The 3 sec data (90m spot heights) which can be use in Ozi3D directly is available here
3 Sec DEM Data
Mayeb this suits you needs?
The new 1 sec data requires large files files relative to the 3 sec data but thats the price you pay for the extra detail.
If you get stuck with the 1 sec data send me rough idea of the area required - I will download tile and convert for you (and send disc) when I get time. Too big to email.
I have had plans of downloading the WA 1 sec data one day anyway - just havent got round to it.
Cheers
Greg
