Loading, Styling and Displaying Ordnance Survey Mastermap Data
with Open Source Software by Jo Cook, Astun Technology
There seems some really polished offerings from companies supporting these open source elements as a integrated software stack for solid enterprise solutions:
But in past few years I have on & off used ID the editor for Open Street Map
and Potlach the flash based editor before that, and been impressed by what is possible in a web browser window.
