AddressList version 10

17 September 2020

We have pleasure in announcing the release of a major new improvement to our popular AddressList program.
AddressList allows the extraction of addresses within a user-defined boundary - a polygon or circle. A limitation has been that for cost reasons map references were stored at the postcode level, not the premise level. This could mean that if the centre of a postcode were just outside the boundary some addresses would be omitted.
However, the Ordnance Survey have recently issued an affordable dataset giving premise-level map references.  Arc en Ciel has incorporated this data so enabling more accurate extractions.
As an example, see the small polygon below that includes the south side of the road where our offices are situated.

The results of the extraction are shown below.
Note how only premises in that part of the street and an adjoining street are included.

With effect from Quarter 1 of this year we are adding What3Words location support to most of our products.
What3Words is a system whereby the earth is divided into 3m x 3m squares, each of which is referenced by a random triplet of words. The illustration below shows how our Address+ product identifies an address in Cambridge by Ordnance Survey grid reference, a longitude/latitude pair and a what3words triplet.

Some believe that what3words or a similar system will replace conventional postal codes in many situations.  In fact the country of Ivory Coast has adopted the system for its own postal service. Click here for details.
