SSQL/MM Spatial defines a well-known text (WKT) and a well-known binary (WKB) representation for each geospatial type. The database supports these standard formats.
The database also supports ESRI-compatible extended versions of these formats (EWKT and EWKB) that include SRID information together with the geometry data. To have geospatial data use these extended formats, specify that a user or profile use one of the "SRID" transform groups. For more information on geospatial transform groups, see ST_Geometry Type Transforms.
