Merestone

Merestone puts the UK's statutory environmental designations on one map, on your phone, in the field, with or without a signal. Official layers drawn straight from Natural England, NatureScot, Natural Resources Wales, Historic England and the Forestry Commission.

A desk study in seconds

Drop a pin, choose a radius, and every designation inside it comes back sorted by distance, with anything on site flagged. Distances and bearings are measured, not eyeballed off a screen.

The report, already written

Export a dated PDF or text extract with a site plan, every record with its distance, direction and source, and just as importantly the layers that were checked and found nothing in. Choose which sections to include before you export.

What is on the map

• SSSI and SSSI Units, SAC, SPA and Ramsar sites
• National and Local Nature Reserves, National Parks and AONB
• Ancient woodland, the Priority Habitat Inventory, wood pasture and traditional orchards
• Open access land, listed buildings and scheduled monuments
• England, Scotland and Wales, with the same map, searches and report throughout

Works with no signal

Download any layer, or the whole country, and it keeps working out of signal. Merestone uses live data when you have a connection and falls back to your download when you do not, and it says which it used, on screen and in the report.
