Hi Wes,
We'd like to introduce native database spatial types and functions in
our ISV ERM products. Our initial plans are just to store points and
polygons, and do proximity searches and contains searches. Oracle,
SQL Server and DB2 all support this, but H2 does only with add-ons
that, as far as I can tell, are LGPL licensed. We are now avoiding
LGPL licensed jars in our delivered products. We are okay with Apache
licenses.
The main reason that add-ons like hatbox are LGPL is that they rely on
the JTS Topology Suite for the geometry heavy lifting (eg point in
polygon) and JTS is LGPL. JTS took a long time and some very bright
geospatial minds to create, so it's difficult to find anyone keen to
start again. The one realistic option is OpenMap from
http://openmap.bbn.com . OpenMap is distributed under its own open
source license (http://openmap.bbn.com/license.html) that bears some
resemblance to the apache license.
Regards,
Peter
