I've worked with spatial data at Ordnance Survey for more than 20 years, usually in rapid application development and data integration projects. Some of the software I have developed is used for editing OS' data, others are used for generating custom product, transforming data from other parties to match it to OS data, or for sharing data between development teams. I am currently preoccupied with finding ways of rebuilding our content store so that it can be delivered in ever more interesting and exciting ways
