Feature Representation

Features are written to the database table with the same name as their feature type, and include geometry as well as attributes as defined on the DEF line.

Geometry Type Description
mssql_spatial_none no geometry
mssql_spatial_point point
mssql_spatial_multipoint collection of points
mssql_spatial_linestring straight line
mssql_spatial_multilinestring collection of straight lines
mssql_spatial_circularstring path consisting of one or more circular arcs
mssql_spatial_compoundcurve path consisting of straight lines and/or circular arcs
mssql_spatial_polygon polygon bounded by straight lines
mssql_spatial_multipolygon collection of polygons bounded by straight lines
mssql_spatial_curvepolygon polygon bounded by a combination of straight lines and/or circular arcs
mssql_spatial_geometrycollection collection of geometries, each of which can be any supported type, including other geometry collections

Geometries may be 2D (X/Y), 3D (X/Y/Z), 2D + measures (X/Y/M), or 3D + measures (X/Y/Z/M).
