Is all the 1 sec (30m) SRTM data already imported into OSM? I saw some
elevation data, but it looks incomplete so I started trying to blend both data
sets.
This project is kicking my ass and I need help melding a lat/lon from OSM to
SRTM lat/lon. I have both datasets in SQL Server and trying to join them
together is the pain point. The pain is either in long query times and/or not
accurate enough lookups. I'm finding SQL Server 2012 spatial is slow (it uses
.NET). The scope of the project is just the USA data.
My server system is:
overclocked and water-cooled i7 3930k (4.1GHZ) 6 cores (plus 6 "Hyperthreads")
32 GB RAM
1.6GB/s disk IO subsystem and 1/2 TB of space. Speed is as indicated by SQL
Server performance monitor. (This can go higher w/more HW RAID controllers that
I already have)
SQL Server Enterprise
Windows Server 2012 Enterprise
Ideas from a 30,000' view on how to do this are appreciated (granular views are
just as good :) ).
