The Hibernate Spatial H2 GeoDB Provider
The H2 GeoDB Provider adds support for H2 GeoDB to
Hibernate
Spatial. It has been tested with H2 GeoDB 0.3
and should work with
any version later than that.
-
Note that H2 GeoDB does not completely implement the OGC Simple
Feature Specification.
Some functions that work for PostGIS or
Oracle
may fail to work for H2
GeoDB.
-
Note that version 0.3 does not store the SRID with the geometry.
This is
due to an omission in the JTS API. Version 0.4 solved this
issue by
extending the JTS API, but the fix was committed in the
opengeo
repository. To use version 0.4, you have to include the
GeoTools Maven repository (
http://repo.opengeo.org/com/vividsolutions/jts/1.12-SNAPSHOT/
) and you cannot use other JTS versions.
-
Note that EWKT byte arrays generated by GeoDB version 0.6 (with
GeoDB.gToEWKB(Geometry)) seem to have redundant bytes at positions
42-45, resulting in a incorrect EWKT. As a result, accessing
EKWT
objects in the database generated by GeoDB.gToEWKB with
hibernate-spatial may give jts Parse Exceptions.
