To use the utility you must run Map Maker Pro and then open the program MMpostcode.
MMpostcode is located in Map Utilities (alongside the Map Data).
You may need to re-import the postcode data occasionally, but it should be retained from one session to the next.
The data is kept in Map Data > Code-Point Open > data
Choose from the UK data set CSV or EH Post Codes.
Enter the postcode and click Go To.
Post codes are represented as Markers, which can be saved as a .dra file (Menu > Markers > Save markers as … ).
Ordnance Survey has recently opened up access to a number of products with the launch of OS OpenData on 1 April 2010, under the ‘Making Public Data Public’ initiative. OS Open Data
Here’s what they say on the website:
OS OpenData will support digital innovation, democratic accountability and social engagement, and will enable business, government, communities and individuals to benefit from easier access to the use of Geographic Information (GI).
There is a specific licence that covers the use of the
OS OpenData products.
Changes: (1) there is NO charge for OS OpenData products and (2) we will have much greater re-use rights under the new licence terms than were previously available for 1:50 000 Gazetteer data.
Check this link out to find out about the new licence regimes, including the Public Viewing Service Licence.
