Hi:

I am currently working on a GML-based neutral format for LiDAR cloud point. I have designed XML Schema.
My demand is: realizaing a module in geoserver, which could convert point type ArcGIS Shapefile or GRASS point format into GML format according to my own Schema.
In previous work, I have no experience in geoserver development. Where should I start? Which module in geoserver is pertaining to implementing such module.

Thanks!

If you want to read your custom format, you will need to create a GeoTools datastore, and should take a look at the docs on http://geotools.org/ . If all you need is output, then I’d recommend looking into a custom WFS OutputFormat. I don’t think there’s a section in the developer manual about outputformats, but the excel extension should serve as a nice template since it is just an outputformat and nothing else. You can find the source for this module at:

http://svn.codehaus.org/geoserver/trunk/src/extension/excel/

Hope this helps.

I don’t have a great understanding of the requirements but this sounds like a common use case of just supporting an application schema? The source data is shapefile correct? In that case no custom module should be needed. Just the app-schema plugin which will allow you to provide the mappings to your custom application schema.
