Dynamic LiDAR · any paid planCawthorn Roman camps© Mapbox, © Maxar
Dynamic LiDAR over Roman camps, North Yorkshire. Satellite imagery © Mapbox, © Maxar. Layer data from the sources named on each card.
Start with the free layers. Pay only if the map earns it.
Inside your free area every layer works except LiDAR.
Recorded finds are plotted by period and free in England and Wales. Tap one to read its record. Find-spots are shown as 1 km squares, not exact coordinates, and the cards show no finder names.
Recorded finds. 1 km squares.
Wales. Coflein historic sites.
An old OS sheet shows what stood on the ground when it was drawn. Lay it over today’s map, with Roman roads and hillforts beside it.
OS, about 1888. Maiden Castle.
Scotland. Roman roads, free.
Ramparts, banks and field boundaries stand out in LiDAR. Change the look on your phone to bring out smaller earthworks. It shows the ground surface the lidar measured, not what lies beneath it.
Maiden Castle. Multi-scale look.
Look card. Nine looks.
Every farm field is coloured each week from satellite images: freshly turned, bare soil, stubble, stubble greening, new crop up, or crop or grass. Tap a field to read its season. Cloud can hide a field for weeks, so check its last clear look.
Week strip. Play it back.
A field. Last clear look.
Season chart. One year.
Turn a field into a permission: landowner contacts with Call, Text and Email, parking and gate pins, rules, agreement photos, and the finds and Trails inside it. Share a permission pack as a file.
NDVI colours every field by how green and strong the plants are. Crop and parch marks can follow buried ditches and walls. Season, crop and moisture make similar patterns, so check them against the LiDAR and old maps.
Dynamic NDVI. Add-on.
Pick the blocks you need and save them with your layers. Your records, search and waypoints keep working with no reception.

Free is free forever. Paid plans start with a 7-day free trial on yearly plans. A card is taken up front, but nothing is charged until the trial ends. Cancel in the app under Settings, then Subscription. Cancel before the trial ends and you pay nothing. Notifications on? We remind you on day 5. Explorer £50 a year or £10 a month, including 20% VAT.
The sources are public, and we name them on every layer. You get the work: merging them into one map, keeping them current, tiling them for offline and drawing every place the same way. Recorded finds, Environment Agency LiDAR, Sentinel-2.
Yes, for the areas you save. Download them on Wi-Fi with your layers. GPS works without reception. Saving new areas needs Explorer. Your free area is saved offline on the Free plan. Dynamic LiDAR saves with your areas.
Private by default. Waypoints, Trails and finds are visible to your account only. Nothing goes to the Community unless you post it. Location sharing runs only in a session you start. Backups go to your own iCloud Drive or Google Drive.
A mapped boundary alone does not tell you whether detecting is permitted. Landowner permission is required before you detect anywhere in the UK. The map shows scheduled monuments and restricted areas and never gives permission.
Start with the free layers. Tap any record to read what it is. Every layer has an (i) that says what it shows and where it falls short. Five short in-app lessons walk you through the map.
Offline mode and a battery-saver GPS mode are built for a full day in the field on most modern phones.
Yes, always. Landowner (and where relevant tenant) permission is required before you detect anywhere in the UK. Detector Maps helps you research the land and shows restricted areas, but it does not give you access. Get permission in writing and agree a finds arrangement beforehand.
Free is free forever. Explorer is £50 a year or £10 a month, including 20% VAT. Dynamic NDVI is an England-only add-on, +£50 a year. Yearly plans start with a 7-day free trial. A card is taken up front, but nothing is charged until the trial ends. Cancel before then and you pay nothing. Notifications on? We remind you on day 5.
Yes, each with its own sources and rules. England and Wales have recorded finds free. Scotland has historic footpaths and Roman roads free, and no Portable Antiquities Scheme records. Dynamic LiDAR is in England and Scotland on the phone. Wales is on the web map now and comes to the phone app in the next update.
From the Portable Antiquities Scheme’s recorded finds in England and Wales. Find-spots are shown as 1 km squares, not exact coordinates, and the record cards show no finder names.
Every farm field coloured each week from Sentinel-2 satellite images: freshly turned, bare soil, stubble, stubble greening, new crop up, or crop or grass. It shows the ground, not permission to detect. Cloud can hide a field for weeks, so check its last clear look.
No. It is a research tool, not a guarantee. Records show where finds were reported. Old maps show what stood there. LiDAR shows the shape of the ground.
Yes, for the areas you save. Download them on Wi-Fi before you go, with your layers. Your phone’s GPS works without reception, so the map, your records and your waypoints keep working. Saving new areas needs Explorer. Your one free area is saved offline on the Free plan.
Yes. Open app.detectormaps.com in your browser and sign in with the same account. Your plan works there too. So do the waypoints and Trails you sync from your phone. The web map needs a connection, so save areas in the phone app for places with no signal.
