Elm Technology is an independent software company. We build research tools that let people study how the ground beneath them has changed — through historical map overlays, high-resolution terrain data, and careful field documentation.
A mobile and web platform used by a growing community across Europe and North America to research the historical landscape: georeferenced historical map overlays, LiDAR-derived terrain for more than a dozen countries and regions, offline field access, and tools for documenting and cataloguing what the landscape reveals.
relichunter.app →Every map and terrain layer we publish is built on licensed or open data, with its source credited in the product. We work directly with national mapping agencies, archives, and open-data programmes across Europe, and we take licence conditions, attribution, and the privacy of our members seriously — user locations in Relic Hunter are private by design and are never shared.
