Ordnance Survey's OXERA study estimated that its data underpinned £100
billion of economic activity in the UK. If the current charging regime is
reducing the size of possible economic activity by even a single percentage
point of GDP, the tax income forfeited could dwarf the entire £50—60 million
that is currently saved by having Ordnance Survey sell information on a cost-
recovery basis. This clearly warrants closer examination.
