Geometry Support

[Adam Estrada <es...@gmail.com>]

All,

We got another Jira ticket[1] to add enhance the geometry support in
SIS.  Does anyone want to volunteer porting this over from GeoToolkit?

Thanks!
Adam

Hello Adam

Thanks for the note about geometry support. Yes indeed, this is a very
important topic. For the geometry projection info (including referencing
WKT parsing), this is actually an independent topic which is the subject
of sis-referencing module. This work exists in Geotk and its port to
sis-referencing will continue as soon as I have finished metadata.

For two dimensional geometries in a Cartesian space, there is a library
by ESRI under Apache 2 license which can be used as a starting point.
This is the library currently used by the sis-shapefile module.

For three dimensional geometries, or for two-dimensional geometries in a
curved space like Earth surface, we may have to write from scratch. 2
PhD students worked on this topic, but we still have no production-ready
library. However the ISO 19107 specification is under revision and not
yet completed. It may be preferable to wait for a stable version before
to work on it. In the main time, maybe the ESRI library can be used?
