HEMA maps have produced a mapping and navigation application for mobile devices, which has much more detailed (and hopefully much more up-to-date) topographic mapping than the old 1:250000 topographic maps that a lot of us have been using on driving holidays and exploratory trips in order to visualize the landscape.
The scale of the new maps is 1:150,000 , which should be a vast improvement over what was previously available for national (electronic) mapping.
This application is still somewhat unstable and buggy at present, but it is a big improvement on the national mapping that was formerly available in electronic form.
