The MAGIC website provides authoritative geographic information about the natural environment from across government.

Information is provided in map layers and you can select what you want. (e.g. land use, soils, habitats, SSSI)

It uses the most up to date 6 inch (1:10000) mapping and provides current administrative boundaries.

Walk Lakes

Provides access to current 2½ inch to the mile OS (Explorer) mapping for whole of England, Scotland and Wales (and various other smaller scales)

[but must register for 2½ inch mapping - free]

Very useful for walkers as you can 'draw' a route on-screen and the site calculates distance and you can download the route as a GPX file to use on a phone or tablet.

Where's The Path

Again designed for walkers. It shows 'map' view and 'aerial' view in two panels side by side on the screen. Move the cursor on one screen and the cursor on the other screen moves to the corresponding point


Current 2½ inch to the mile OS (Explorer) mapping for whole of England, Scotland and Wales (and various other scales)
