Observation + interpretation
Interpretive stratigraphic column
Cross-section comparison
Correlation panel
Age model
Constraint intersection
Section-local biostratigraphy
Fossil occurrence ranges
Ranges shown here are first and last observed occurrences within this measured section only; they are not global taxon ranges.
Waypoint overview
Local station map
Offline coordinate plot only; no basemap or network connection is required. North is up and east is right.

Teaching dataset
Adds three linked stations, structural measurements, samples, and paleocurrent observations without replacing your current work.

Every section exports stable rock, mineral, bed, sample, and locality links under the section schema geochem-stratigraphy/1.0 and field schema geochem-field-geology/2.0.
Version 3.0
Measured Sections + Field Geology + Stratigraphic Intelligence
Version 3 preserves the complete measured-section and field-geology workspaces while adding explicit facies, depositional-environment, lithostratigraphic, sequence-stratigraphic, chronological, fossil-range, and cross-section correlation layers. Raw observations remain separate from every interpretation.
- Multiple projects and sections with local autosave.
- True-thickness column scaling with standard lithology patterns.
- Contacts, sedimentary structures, fossils, samples, photographs, and GeoSuite links.
- Undo/redo, drag reordering, versioned JSON, SVG/PNG, CSV, Markdown, and print output.
- Offline, dependency-free HTML/CSS/JavaScript architecture.
- Field stations, degree-based structural attitudes, stereonet preview, GeoJSON, sample inventory, photo log, and sketches.
- Facies shorthand, environment suggestions, formation/member hierarchy, sequence surfaces, age constraints, fossil occurrence ranges, and user-reviewed cross-section correlation.
Field-use cautions
- Measured thickness should be corrected for bedding attitude and traverse geometry when needed.
- Lithology patterns are graphical conventions, not substitutes for detailed descriptions.
- Interpretations should remain separate from direct observations.
- Browser storage can be cleared; export important projects as JSON.
Built-in validation
Run both regression suites to verify measured sections, field stations, structural attitudes, exports, links, and schema integrity.
