Over the summer we’ve taken the opportunity to update some of the maps used in Digimap for Schools. The Ordnance Survey have been working with their Mastermap collection and had a slight rejig of some of their classifications and added some new data schema’s. (at this stage you can tell I’m not a professional cartographer ;-))
As a result there have been some additional classifications added to their data which allows for better cartographic representation of the data itself (i.e. they can put more information on the maps). To the casual observer who maybe doesn’t have a forensic eye for detail many of these changes may not be glaringly obvious but we have found a few examples of how the data has changed the maps for the better! We found that some of the best examples of this tend to be in the coastal regions and below is an example of a before and after:
As you can see form the top image the area is simply classified as shingle and rock, whereas the image below is much more refined in giving better classification of the areas.
Anyhow this was just a quick update to let you know that some of the maps may have changed slightly (for the better ;-))
