Info

Registration and SRID • What is an SRID – ArcGIS: complete spatial reference (sde_spatial_references) • offsets, scale, units, cluster tolerance, coordinate system – Geography: coordinate system (sys.spatial_reference_systems) – Geometry: Arbitrary but required • Registering a table with existing features Existing SQL Server SRID is recorded in – Existing SQL Server SRID is recorded in sde_spatial_references (auth_srid)
Registering empty tables • ArcGIS sets SQL Server SRID – Geography: epsg code from sys.spatial_reference_systems – Geometry: epsg code from sys.spatial_reference_systems (if any) OR ArcGIS SRID • Workflow: Geography – Provide –G with valid coordinate reference – If no –G specified default is 4326 WGS84 • Workflow: Geometry – Using SQL, insert single feature with desired SRID – Provide –G with valid coordinate reference – Delete dummy feature after registration • Alternatively, use –R option to use existing ArcGIS spatial reference
