Hi Puneet.

Thanks for the comments.

Its hard to get a feel for the 'number' of silent ones...



You may not want me getting my hands dirty in code development again.... 
its been a long time ;-).

My current focus is on advocacy and on trying to get a big picture 
overview of OS Spatial so that I can work out where I can best help, 
rather than just jumping in blindly. 

With the advocacy, I may be able to help get additional resources assigned 
to some OS Spatial and OSGeo Projects. There are already Australian 
government resources going into the development of:

- GeoNetwork (to support ANZLIC's adoption of GeoNetwork 
(http://www-ext.osdm.gov.au/osdm/policy/metadata.html)) 

- GeoServer and GeoTools (CSIRO work on complex objects to support 
GeoSciML):

wrt the big picture work, I intend sharing what I have currently in the 
near future. I'll post more on this later.

wrt imagery in Postgres, there is already work happening in this space. 
The Brazillian TerraLib project supports raster in Postgres. There have 
also been others mentioned in this thread. How can other projects take 
advantage of and further this work?

I'll do this as soon as time allows (and I learn how to edit a wiki).
