Outcrop
Read the rocks around you. Hold up your phone and Outcrop draws the geologic map onto the land in front of you, each rock unit named. It works offline too.
Free, for iPhone and Android. Geologic maps worldwide from Macrostrat.
Each unit’s page in Outcrop shows where its age falls in Earth’s 4.5 billion years.
Hover over or tap the line to read a period or an event.
Hold your phone up to a canyon wall, a road cut or a far ridge. Live draws the geologic map onto the land through your camera in augmented reality, names the unit under the reticle and outlines it, and labels the peaks and lakes in view.
The map opens on the rock where you’re standing: its name, its age, what it’s made of and how it formed. Pull it up to see the column of rock below you and the fossils found in it. Tap anywhere else to read that spot instead.
Read the bedrock and its faults anywhere on Earth from Macrostrat’s geologic maps. Switch to Quaternary geology for the glacial and river deposits on top and the faults that have moved recently. Then the soil and the plants that grow in it. On the map and in Live.
Outline the ground you’re headed for. Its geologic maps and soils are saved on your phone with the terrain Live draws on, its labels and the basemap. Add satellite imagery if you want it. The map and Live then work with no signal. Only the active faults need a connection.
Coming soon to iPhone and Android.
