Muld is a metal-detecting app for Denmark. Find old sites with LiDAR terrain and historical maps, see every protected zone before you dig, and keep your finds on your own phone.
FEATURES
• LiDAR terrain — spot barrows, hollow ways, and ploughed-out features that aerial photos hide. Built on Dataforsyningen's national elevation model.
• Historical maps — switch between 1800s, early-1900s, and modern aerial imagery in a single tap. See where the old farmsteads, roads, and fields actually were.
• Protected zones — fortidsminder, beskyttede sten- og jorddiger, and kulturarvsarealer rendered on the map; tap any zone for its rules.
• Find journal — log unlimited finds with photos, depth, notes, and GPS. Stays on your device until you decide what to do with it.
• DIME submission — submit finds straight to the national metal-detecting register, pre-filled from your journal entry.
• Session tracking — record the path you walked. Keeps recording with your phone in your pocket. Compare routes with previous sessions.
• Journal export — export your journal as HTML, CSV, KML, or GPX. HTML reports include your photos.
• Offline maps — download map areas before you go. No signal needed in the field.
