I wonder if there is any optimization I can do to achieve faster SELECTs for spatial data without moving to SQL SERVER 2008. There is for SQL Server 2005, natively or through plugins, any of the features below?
- Spatial field types
- Spatial indexes
- Arcsin math function for surface distance calculation on a sphere (Earth)
There are some GIS features available through http://www.codeplex.com/Wiki/View.aspx?ProjectName=MsSqlSpatial but as far as I know SQL 2008 is the way to go
