Re: [Geotools-devel] Request suggestions for implementing a Lidar capability for GeoTools

[Jody G. <jod...@gm...>]

That would very much be welcome, we have a community module process to get
you set up for collaboration quickly and then the work gets reviewed and
included in the library when you are ready.

GeoTools is set up with the core library, plugins that add capability to
the core library, and then extensions (such as graph processing, wms and
tile clients that build on top of the core library). Depending I how your
work takes shape you may end up with another extension, or a new section of
the core library.

Did you mind checking the developers guide and letting us know if you have
any questions on how to get started. There is a bi weekly Skype chat you
are also welcome to attend fornanmore casual discussion).
