com.luciad.format.sqlite.geopackage.TLcdGeoPackageExtension

public class TLcdGeoPackageExtension
extends java.lang.Object

Description of a GeoPackage extension. A GeoPackage Extension either profiles / extends existing requirements clauses in the geopackage specification or adds new requirements clauses. Existing requirement clause extension examples include additional geometry types, additional SQL geometry functions, and additional tile image formats. New requirement clause extension examples include spatial indexes, triggers, additional tables, other BLOB column encodings, and other SQL functions. This implementation currently supports the following extensions:

• gpkg_rtree_index: embedded rtree spatial indices
• gpkg_geometry_type_trigger: SQL triggers that enforce geometry type constraints
• gpkg_srs_id_trigger: SQL triggers that enforce SRS constraints
• gpkg_geom_CIRCULARSTRING: the 'circular string' geometry type
• gpkg_2d_gridded_coverage: tiled gridded coverage data
• lcdx_geom_CIRCLE: the 'circle' geometry type
• lcdx_geom_ELLIPSE: the 'ellipse' geometry type
• lcdx_geom_ELLIPTICALARC: the 'elliptical arc' geometry type

Since:

2013.1
