I see that Oracle's SDO_CS package is able to do datum transformations. I'd like to do datum transformations in SQL Server.

I searched, but have not found something like this for SQL Server.

Is there a SQL Server package similar to Oracle's SDO_CS?


SQL Server Spatial Tools is a CLR assembly that you can add to your database to assist with a number of operations that didn't come built in with the original release of SQL Server spatial objects.

It has a set of functions to do similar operations as those found in Oracles SDO_CS. There is a projection example in the source code section, though it doesn't look that helpful to me.

  • Thanks, I need datum transformation capability though. NADCON and NTv2 implementation would be great. – Kirk Kuykendall Jun 28 '16 at 21:31
  • @KirkKuykendall unfortunately I haven't seen any packages that do the NTv2 or NADCON transformations. – MickyT Jun 28 '16 at 21:41

We are dealing with this issue right now and are looking at the DotSpatial library for .NET since it appears to have support for NADCON and NTv2.
