Pictometry® is not an Ordnance Survey product.
BLOM Aerofilms Ltd., a private sector company, has the rights to market a Pictometry product in the United Kingdom. The product combines BLOM Aerofilms’s oblique aerial imagery with viewing software patented by an American company, Pictometry International Corp.
Ordnance Survey has a non-exclusive commercial agreement with BLOM Aerofilms to act as an authorised reseller of Pictometry of Great Britain. Information on sales of licences to use Pictometry within the United Kingdom is commercially sensitive to BLOM Aerofilms Ltd., given that there are other commercial providers of potentially competing products.
