Nonlinear Geometry Types Extension ¶

This extension allows the use of extended geometry types.

gpkg_extensions¶

Add a row to this table for each geometry type in use as described in Table 1.

Table 1: `gpkg_extensions` :widths: 20 80 :header-rows: 1¶
Column	Value
`table_name`	table containing extended geometry
`column_name`	column containing extended geometry
`extension_name`	`gpkg_geom_<gname>` where `<gname>` is the uppercase name of the extended geometry type
`definition`	http://www.geopackage.org/spec130/#extension_geometry_types
`scope`	read-write

When using this extension, use the appropriate type code in the geometry type byte of the geometry. The X bit is 0. (An X bit of 1 only applies when using the now-deprecated User Defined Geometry Types Extension of GeoPackageBinary Geometry Encoding).
