Transform your smartphone into a geological field assistant.
Lithotheque is the professional app designed for geologists, Earth science students, paleontologists, and mineralogy enthusiasts. Replace your paper notebook, compass, and maps with a complete, secure, and fully offline digital solution.
MAIN FEATURES:
🌍 Mapping & Geolocation
Specialized Base Maps: Access global geological maps (Macrostrat) and French maps (BRGM / InfoTerre).
Offline Mode: Download and cache map tiles to work in dead zones without any internet connection.
Geolocation: Automatic recording of GPS coordinates (Latitude, Longitude, Altitude) and address conversion.
⚒️ Structural Measurement Tools
Integrated Compass & Clinometer: Instantly measure Dip and Strike/Azimuth of planes and lineations by placing your device on the outcrop.
Stereonet: Visualize your structural measurements directly on a Schmidt or Wulff net and calculate mean vectors.
Augmented Reality (AR): Locate your sampling points and visualize distances and orientations in real-time via the camera.
📝 Digital Field Notebook
Detailed Sheets: Input lithology, stratigraphy (integrated ICS chronostratigraphic chart), texture, minerals, fossils, and chemical tests (HCl).
Photos & Sketches: Take photos and annotate them with sketches directly in the app.
Field Checklist: Never leave without your gear (hammer, hand lens, PPE) thanks to the integrated checklist.
🤖 Advanced Artificial Intelligence
Local AI (100% Private & Offline): Use visual recognition and voice dictation to fill your notes without sending data to the internet.
Scale Detection: The AI automatically verifies if a scale (coin, hammer, pen) is present in your sample photos.
Cloud Assistant (Optional): Connect your Gemini API key to enrich descriptions, obtain paleogeographic contexts, or tell the geological history of your samples.
📂 Exports & Reports
Standard Formats: Export your data to your favorite GIS software (QGIS, ArcGIS, Google Earth) in CSV, GeoJSON, GPX, and KML.
PDF Reports: Automatically generate printable PDF sheets of your observations.
ZIP Backup: Archive all your data and images in a portable ZIP file.
🔒 Privacy & Security
Local-First: Your data belongs to you. Everything is stored locally on your device. No account creation is required.
Encryption: Your personal API keys are encrypted with AES-256.
Whether you are doing mapping, sedimentology, metamorphism studies, or simple sampling, Lithotheque is the tool that accompanies you everywhere, from the laboratory to the most remote terrains.
