Re: [udig-users] JTS Geometry and CoordinateSequence Factories Code Example?
|
How did you end up on this one? There has been a lot of work on an EMF based datastore lately on the uDig and GeoTools lists that should cover the same topics?

Dear All,
I am about to conclude my PhD research on the development of cadastral
systems, and I have managed to complete a small implementation test on
the Eclipse platform, using a Eclipse Modelling Framework Code Generator
to get Java classes from an Ecore Model.
I have a preliminary schema generated in a PostgreSQL/PostGIS data base,
through the corresponding facility in Hibernate Tools. This part of the
work has used Hibernate-spatial in order to generate a geometry column
in the designated table.
My current research platform lies on an Ubuntu machine, with a
configuration as follows:
Eclipse v.3.5.2
EMF v.2.5.0
Hibernate Tools v.3.2.4
Hibernate-spatial v.1.0 M2
PostgreSQL v.8.3.8
PostGIS v.1.3.5
My request is for any plain (POJO) Java code examples which use the JTS
CoordinateSequence and the GeometryFactory classes, in order to specify
a Geometry object (I will use a MultiLineString in the test). In
particular, I would like to establish a PrecisionModel and a SRID other
than the default.
Although this request is about the use of JTS and not specific to uDIG
functionalities, I hope that the Eclipse + Geotools (and hence, JTS)
framework uDIG uses can get me some answers. I have put a similar post
to the Hibernate-spatial list.
I know this is a rather involved request, for most of the examples I
have seen so far simply use the WKTReader to define the Geometry in the
Java domain.
Any hints or suggestions will be greatly appreciated.
Kind Regards,
João Paulo Hespanha
