Hi,
I am Juan Carlos Ortiz. GIS and Web Application Developer... and Open Source
newbie. Before anything else, congratulations to all people involved in
this excellent API.
I'm starting a new project and decided to use Geotools for it. I´m new to
Geotools (and not an advanced Java developer) but I know I
can accomplish the goals of this project with it. But... I have this
problem. As long as I could see, the API only supports 2D geometry and I
need linear referencing with 3D "AND" M (measure) support (ala ESRI SDE
API). So I have this proposal for a module I like to share.
I created a group of classes extending Coordinate, PackedCoordinateSequence,
and PackedCoordinateSequenceFactory, called Coordinate4D,
PackedCoordinate4DSequence, and PackedCoordinate4DSequenceFactory
respectively. I can then create Geometries backed with this classes to
support the 4 dimensions (x,y,z,m) but keeping the geometries conformal to
the API.
The next step would be to create a new package
com.vividsolutions.jts.linearref.zm with some of the classes of the base
linearref package modified to support 3D and M based linear referencing.
For now this would be to the extent of what I need for my project, but I
think it could be a good starting point for a complete implementation.
I will appreciate your opinions on this. Am I going in the right track? Are
there better approaches to the problem? Maybe some solution already done
out there I missed? Is it worth continuing?
Once again congrats to all of you for the great job.
Kind regards,
Juan Carlos Ortiz G.
