[Opensim-users] Re Hatching: Real life Terrain

[InuYasha Meiji]

I asked this before, and I did get a good reply from a user on the list 
named, Marcus Llewellyn.  His links helped, and I was able to find the 
srtm data I wanted from a file called srtm_62_07.zip.  I realize this is 
not the best in resolution.  but I want to find out for sure.  Has 
anyone found a way to get accurate land elevations to a real life 
scale.  Or is everyone that uses SRTM (Shuttle Radar Topology Maps) or 
GIS to make region height maps only making mini model scaled down 
versions of the real life land scapes? 

I was hoping for a real life 1:1 of the land elevations of a mile to fit 
a 7x7 equal to a 1792 x 1792 area with Shuri Castle in it's center.  
Yes, Shuri Castle, Okinawa, Japan.

Any ideas on how to do this for open sim?  I don't want to make a mini 
model of the entire Ryukyu Island chain.  I only want the area with the 
Castle at the 130 meters above sea level and the rivers, lakes and ponds 
of the area around it.  From what I read, it seems like it might be 
impossible, but I may have misunderstood.

Thanks for your time on this.  I wanted to know before my eyes fall out 
searching the net.  ;)
