[udig-devel] uDig geospatial reports (was Server-side uDig)

[Aleksander Bandelj]

Well, our /long/ term plan is to add the following to BIRT:

- spatial data source (geotools FeatureCollection from spatial query on 
FeatureSource), which can then be joined with other BIRT data sources
- spatial data series over data source
- spatial data grouping, so that you may render features on several 
maps, given some minimum zoom scale or some guiding geometry
- and of course map chart type

But, the above is a lot of work, especially since not all necessary 
extension points for the above are present in current BIRT, so you have 
to modify BIRT core bundles. Even worse, PDF is our primary output 
target and current PDF chart rendering inside BIRT is a kludge (it 
constructs a SVG document, which is then drawn to PDF through batik 
renderer). This is somewhat problematic since maps frequently involve 
large raster images. ;)

Our current solution (more or less) is to plug uDig rendering directly 
into pdf emitter, so that an image report item with special URL is 
considered to be a map. uDig renderer registers at the emitter through 
extension point. We'll develop a custom geographic map report item later 
on. I would be interested in what approach have you chosen.
