Trying to build one database with SRTM 1 sec (30m) data and OSM data of the USA
is kicking my ass. I'm reaching out for help. 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 associate SRTM elevation for any OSM
lat/lon point via SQL query on my server is appreciated (granular views are
just as good :) )
