Detector Maps
Draw around a patch and it rises in 3D from the 1-metre survey. Raise the height, drape any layer over it, and let the detectors mark the ground worth a closer look.

Shown: Terrain+ in the web app at Malakoff Diggins, California.
They read the shape of the ground in the 1 m survey and mark where it’s worth a closer look. They point you at ground; they can’t promise gold.
Wattle Gully, VICRaise a gully from the state 1 m survey, then let the gold detectors mark worked ground, likely shed gold and flood trap sites.
Malakoff Diggins, CAHydraulic pits, tailings and benches stand up in 3D from USGS 1 m LiDAR, with the same three gold detectors.
Maiden Castle, DorsetRead earthworks in 3D. Detectors mark ridge and furrow, banks and ditches, Roman camp corners, and ground that looks like known hoard and settlement settings. Only on land you have permission for; scheduled monuments are off-limits.
Raise farmland and moor from Scotland’s LiDAR and read the shape of it before you knock on the door.
Terrain+ and Dynamic LiDAR from Wales’s own 1 m survey are live on the web app. The phone app gets them in the next update.

No app can promise that. Terrain+ shows you the shape of the ground and marks where it’s worth a closer look, so you spend your day on better country.
New South Wales, Queensland and Tasmania with Explorer, and Victoria with the LiDAR add-on. Western Australia, South Australia and the Northern Territory don’t have LiDAR to build from yet.
