About

Outcrop

This app aids geologists in field studies by allowing them to capture high-resolution images of outcrops. Users can interpret geological features, add annotations, take measurements, and export data to construct 3D geological models.

Highlights
  • High-resolution outcrop imaging
  • Interpretation of facies, structures, and boundaries
  • Annotation and measurement tools
  • Dip and azimuth measurement
  • GPS location integration
  • 3D geological model export (GOCAD format)
Features
Read full description

This application is designed for the geologist to use during field studies. It lets the user take pictures of the outcrop, interpret the high resolution image and export this information in 3D to construct a 3D geological model. On the image, the user can interpret facies intervals, sedimentary structures and boundaries. The user can add annotations anywhere, measure width/height of sediment bodies (channels, lobes, etc.), and compute bodies statistics. Using an iphone or ipad, the user can measure dip and azimuth and locate this measure on the picture or use its GPS location to export dip markers to the 3D model. Once the user defines the image scale, all interpreted boundaries and intervals can be exported in 3D in GOCAD format (image, interpretations boundaries, dip/azimuth and facies intervals).

About

DipStrike

Read full description

DipStrike is an offline-first field notebook built for structural geology. Its high-contrast controls, large capture targets, and quick sensor workflow are designed for gloves, glare, and hands-busy work. Record manual or sensor-assisted strike/dip and trend/plunge readings. Speak a field note and review its on-device transcript and structured fields before saving. Track sample bags by QR code, add GPS waypoints, browse an online field map, and export measurements or samples as CSV. Your fieldwork deserves more than scattered notes and forgotten photos. DipStrike brings a geological compass, clinometer and field notebook together on your iPhone and iPad. Capture strike and dip, record observations, and keep specimens connected to the places you found them. Built for geology students, field geologists and researchers—from your first outcrop visit to a multi-day mapping project. MEASURE. RECORD. KEEP THE CONTEXT. • Capture strike/dip and trend/plunge with manual or sensor-assisted readings. • See compass heading, dip angle and dip direction together. • Review a visual diagram of your saved measurement. • Use magnetic bearings or apply a trusted local magnetic declination. A FIELD JOURNAL THAT FOLLOWS YOUR DAY Create a journal for a field trip, research project or mapping campaign. Record arrival and departure times, browse each day’s logs, and keep readings, observations and specimens together. Just taking a quick reading? Use Quick Logs without creating a journal, then organize them later if you choose. SPEAK YOUR OBSERVATIONS Start a voice memo with one tap. Keep the recording and transcribed text so you can revisit what you noticed at the outcrop. Prefer typing? Save a written memo instead. REMEMBER EVERY SPECIMEN Record rocks, minerals and other field samples with multiple photos, notes and location details. Each specimen gets a record ID, whether you collect it or leave it in place. A sample bag is optional. CONNECT YOUR WORK TO THE MAP Create field stations for observation sites and link their measurements, memos and specimens. Revisit a station to see what you recorded there. YOUR RECORDS, UNDER YOUR CONTROL Your field records are stored on your device. Capture and browse saved records offline; loading map imagery requires an internet connection. Export measurements and specimens as CSV, or back up journals with their photos and voice recordings to Files. Optional reminders help you remember to make a fresh backup. No account or subscription required. All current features are free. IMPORTANT Phone sensor readings can be affected by magnetic interference, device placement and calibration. Confirm critical measurements with appropriate field instruments and professional judgment. Back up important records—deleting the app also removes its local data.
