Stereonet & Structural Analysis
GeoKit turns the strike & dip measurements you collect in the field into an interactive stereonet, strike rose diagram, and dip histogram — automatically, on your phone. See your structure emerge as you map, without exporting to desktop software.
Three Views of Your Structure
Equal-Area Stereonet
A lower-hemisphere Schmidt net plotting your planes as poles or great circles. Tap any pole to read its measurement. Spot clusters, girdles, and preferred orientations at a glance.
Strike Rose Diagram
A bidirectional rose of strike orientations in 10° sectors — instantly reveals the dominant structural trend across an outcrop or a whole survey.
Dip Histogram & Stats
Dip-angle distribution in 10° classes, plus live stats: count, mean dip, dip range, and the dominant strike trend — a quick quantitative summary of your data.
Analysis in the Field, Not Just at the Desk
Traditionally, structural analysis happens after fieldwork — you record measurements on paper, type them into desktop software, and only then see the stereonet. GeoKit closes that loop. Every strike & dip you record and every fault marker feeds the plot in real time, so you can spot a fold hinge or a conjugate fracture set while you're still standing on the outcrop.
The projection is a proper lower-hemisphere equal-area (Schmidt) net — the same math trusted in structural geology — so the plots are publication-adjacent, not a toy. And because readouts honor your chosen convention (dip direction, right-hand rule, or quadrant), the numbers match the way you and your team already work.
Prefer the desktop? Every measurement still exports cleanly to GeoJSON, KML, or CSV for QGIS, ArcGIS, or your favorite stereonet software.

Who Uses Structural Analysis?
Students
Learn to read a stereonet with your own measurements. See poles cluster and girdles form as you plot real field data.
Structural Geologists
Identify fold axes, fracture sets, and fault populations on the outcrop — before you leave the field.
Exploration & Mapping
Summarize bedding and joint orientations across a survey area and export the data for further GIS analysis.
Structural Analysis FAQ
Does GeoKit have a stereonet?
Yes. GeoKit builds an interactive lower-hemisphere equal-area (Schmidt) stereonet from your strike and dip measurements and fault markers, with a poles or great-circles view, a strike rose diagram, and a dip histogram — free and offline.
Which measurements feed the structural analysis?
Every strike & dip measurement you record and every fault marker (which also stores strike and dip) are plotted together. You can filter to just measurements, just faults, or all data.
Does it support dip direction and right-hand-rule conventions?
Yes. GeoKit lets you display orientations in dip-direction, right-hand-rule, or quadrant format, so the readout matches your workflow — useful for international teams and universities.
