2009 Annual Data Update

New data
On Thursday 17th September EDINA released all available updates for data provided through Digimap's Ordnance Survey Collection. Details of the versions of all the data offered can be found on the EDINA website here. The Digimap licence also now offers MiniScale and the OS 1:250,000 scale colour raster data. These are currently available through ShareGeo and will be added to the Data Download as soon as possible.

Architectural Changes

As well as updating the data, other significant changes have been made to the underlying technologies supporting Digimap. In short, we have replaced the entire GIS architecture which produces the maps you see online.

The new software, from Cadcorp, offers a number of benefits to both EDINA and end users of Digimap. As well as enhanced quality maps and faster map generation online, the printed output gives crisp, clear maps as PDF files. EPS files are no longer available from any facility within Digimap's OS Collection, including Carto, but EDINA is working on the provision of additional formats to PDF.

New mapping facility: Roam

With the arrival of the new GIS software, EDINA has also developed a new mapping facility, called Roam. Still in a development phase, Roam offers the usual search functions as well as "slippy maps", the click-and-drag function used to position a map, familiar to users of other popular online mapping facilities. It is easier to locate your map, easier to zoom in and out, and now offers maps at 12 different fixed scales. An additional small scale Ordnance Survey mapping product, MiniScale, has been included, and other datasets (e.g. Strategi and OS MasterMap) are available at more than one fixed scale.

Currently Roam is available as a Beta facility to site representatives only until Monday 5th October, when it will become available to all registered users of Digimap's Ordnance Survey Collection. Roam is available from the OS Collection Home page; you will find the new icon next to those for Classic and Carto. It will be greyed out if you don't yet have access to it.

Roam will run in Beta alongside the current Classic facility until January 2010 when Classic will be withdrawn entirely. Regular updates will be made to Roam to add new functionality, such as MyMaps, prior to its release as a full service in January 2010.
