Bonjour

Encore une initiative interessante de l'Ordance Survey, l'institut cartographique du Royaume-Uni : l'OS se procure aupres des arcitectes, promoteurs, amenageurs et services publics les plans des projets d'amenagement ou de construction (jusqua 5 logements). Cette founiture est remuneree. Les donnees ainsi collectees sont gerees dans une couche speciale consacree aux amenagements projetes ou en cours. Elles font ensuite l'objet d'une verification sur le terrain avant d'etre integrees completement a la base de donnees de l'OS.

Un bel exemple du pragmatisme anglais mais aussi d'une approche donnees mise en place rapidement, sans des annees d'etudes prealables et de developpements... Beaucoup de donnees existent... c'est leur acces qui fait defaut.

Cordialement

G.B.

Le communique de l'0rdnance Survey

OS More than 2,500 site plans showing 88,000 houses and other proposed developments
have been supplied by architects, house builders and developers to add to Ordnance Survey's
most detailed digital map data. It follows the launch of an Ordnance Survey initiative to gather
design plans and engineering surveys for sites with detailed planning approval but still
awaiting construction. The initiative, called CODES (Collection of Data from External Sources),
includes industrial, commercial, infrastructure and residential developments, with future
projects as small as five houses being accepted. Ordnance Survey buys in the data from site
plan owners across Britain and processes the information to bring it in to line with Ordnance
Survey specifications and the National Grid. It is then held as a special layer within its main
database. When construction takes place, the data is verified and updated where necessary
by Ordnance Survey staff on the ground and transferred to the main topographic layer of the
database - a much faster process than surveying from scratch.
This means that as well as the financial incentive for providing plans, suppliers benefit from
knowing their developments will be on the map earlier than would otherwise be possible.
We want even more owners of site plans to come on board and share in the success of
CODES, says Neil Ackroyd, Ordnance Survey's Director of Data Collection and Management.
Over the past 18 months we have secured agreements with several leading architectural
firms, civil engineers, consortiums and government departments. It's a new way of working for
us, and it's already helping to improve the efficiency of our update processes to everyone's
benefit.
