Outcrop wants to put the rock map in the viewfinder
Outcrop is a forthcoming phone app that overlays geologic maps onto the landscape through augmented reality, with details about rock units and offline map access.
- For
- Hikers, travelers, and geology field observers
- Worth noticing
- The page says saved maps, terrain, labels, and basemap are intended to work offline; active-fault data still needs a connection.
Field notes
The page lays out a field workflow around a live camera view: map units are meant to be outlined and named against visible terrain, with peaks and lakes labeled as well. A tapped location is described as opening information on rock age, composition, formation, and fossils. The proposed offline package includes maps, terrain, labels, and basemap, while active-fault data is an explicit exception. The app is identified as forthcoming for iPhone and Android.
