Well done to Leicestershire on its online mapping project of the County Definitive Map. The web site is walker friendly and contains first class maps and Definitive Map information such as Footpath numbers and routes. It's fast and easy to navigate.

What has Derbyshire been up to? Well, nothing near as good. To view the mapping portal you have to sign an online agreement! Then what you get is nothing better than the offering of multimap, streetmap.co.uk or viamichelin. I wonder how much all this is costing?
The mapping for walkers provides little more than is provided by OS. Perhaps I'm missing something. The old maps are interesting but sometimes the sheets do not abut (though they do on their original sites).
We, in Derbyshire, have more attractive countryside (I am biased here!) but worse DM mapping and much poorer footpath signage.
