User Friendly Access to CRS Module

[Sunburned Surveyor]

I know that GeoTools has a great CRS module. I'd like to know if there
has been any effort to package the functionality of this module in a
user friendly executable program. I was thinking of a some code that
would show a simple Swing GUI that would allow the user to input the
following data and then perform a CRS transformation:

[1] Source data file.
[2] Destination data file.
[3] Source CRS EPSG code or WKT CRS definition.
[4] Destination CRS EPSG code or WKT CRS definition.

Has anyone coded a simple tool like this, using the GeoTools CRS
module? I know UDig has some reprojection support, but I've been
having trouble with it. I think it would be great to have a simple
tool to do reprojection of GIS data using GeoTools, and I think this
tool could see some heavy use.

If we don't have an existing tool, I'd like to think about coding one
for my own use. Would this have a home in Geotools? Could we include
it with the CRS module? Would you guys have suggestions on the
implementation of this tool?

If I tried to code this tool, I'd get it working with just Shapefiles
at first. Then I might be able to add other common GIS formats
supported in GeoTools.

Thanks,

Landon

The CRS lab is a little bit friendly (swing app) and shows how to do  
this. It shows a preview; and allows you to export a transformed file.
You may wish to extend it since it is just a tutorial right now.

Hi Landon,

One thing I have started working on is called GeoScript. It is
essentially a project to build bindings around geotools in other dynamic
scripting languages like javascript and python, for those who are
willing to take the hit that comes with using a dynamic language.

Hi Landon,

The CRS Lab that Jody mentioned is at:
http://geotools.org/examples/crslab.html

Any comments that you have on it would be much appreciated.

Hi Justin - great idea !  Are you using ANTLR at all ?  (I'm a big fan
of ANTLR :)

Hi Landon,

long time ago I did a school project on this topic and here is the result:

http://gist.fsv.cvut.cz:8080/webref/

It is prepared just for text files that contains coordinates but extension for shapefiles should be also simple.

Regards,
Jan.

Hi Jan,

Thanks very much for posting the link to your page.  I'd like to link
to it in the new GeoTools page example page, CRS Lab - would that be
ok with you ?

Michael
