# RightSlope | Rock Slope Stability > Rock slope stability, from field mapping to the right face angle. One scanline file becomes the stereonet, the sector-by-sector kinematic analysis, the factor of safety across four failure modes and the optimized face angle — the integrated equivalent of tools like Dips, RocPlane, SWedge and RocTopple, in a single workflow. - PDF, Word and Excel reports - English, Portuguese and Spanish - Your data isolated per user Links: [Start free](https://app.rightslope.io/register) · [Sign in](https://app.rightslope.io/) · [Tutorials](https://rightslope.io/tutoriais.html) ## One project, from field data to face angle. RightSlope assesses rock slope stability from structural mapping data. It combines the statistical treatment of discontinuity orientation data, kinematic feasibility testing of the main structurally controlled failure modes, and limit-equilibrium factor-of-safety calculations for each mode and slope sector — all in one project, with no exporting and re-importing between programs. - **4** — Failure modes assessed - **360°** — Pit sectorization (Pro) - **10** — Discontinuity sets - **3** — Languages in app and report ## Five tabs, in the natural order of the work. Move between them freely: results already computed are preserved as long as the input data does not change. ### 01 · Data Upload the survey as .csv, .xlsx or .xls. Preview it, filter by scanline or discontinuity type, and apply the magnetic declination correction. ### 02 · Stereonet Discontinuity sets are identified automatically by statistical clustering, with pole density, great circles and set intersections. You can add manual sets. ### 03 · Kinematic analysis Every slope sector is tested for planar sliding, wedge sliding, flexural toppling and direct toppling. The matrix shows where risk exists and the rose summarises it by direction; click a cell to inspect the critical zone on the stereonet. ### 04 · Factor of safety For each admissible mode, FS is computed by limit equilibrium accounting for block weight, water and the shear strength of the sliding surface. Each result expands into its geometry, forces and governing mode. ### 05 · Slope optimizer Find the steepest face angle that still meets your target FS, sector by sector, for both the bench and the overall slope. ## What the app does with your data. Minimum columns dipdir and dip. Optional columns unlock more: scanline, quantity, type, strike, and JRC, r, R. ### Field data Reads .csv, .xlsx and .xls, with scanline and type filters, per-measurement multiplicity and strength-criterion pre-fill. ### Stereonet and statistics Equal-angle (Wulff) lower-hemisphere projection. Automatic clustering into up to 10 sets, pole density by kernel estimation and Fisher concentration per set. ### Sampling corrections Magnetic declination correction and Terzaghi weighting for scanline sampling bias. ### Sector-based kinematics A sweep across 8 or 9 dip-direction sectors — or a single direction, for an isolated slope — with configurable friction cone and lateral limits. ### Factor of safety Four modes: planar, wedge (3D vector formulation), direct toppling and block-flexure toppling. Parametric water models, bench-width effects and FS banding. ### Scenarios Variations inside the same project — dry versus saturated, for instance — sharing one data file, with a side-by-side comparison tab and a dedicated report section. ### Reports PDF, Word (editable) and Excel, with methodology, bibliography and every chart. In all three languages. ### Mohr-Coulomb or Barton-Bandis — even from the Schmidt hammer. The Barton-Bandis inputs can be estimated from Schmidt-hammer field data, including scale and impact-direction corrections. ## The document you hand to your client. A complete report comes out of the project ready for review and signature: cover with project identification, input data, stereonet, kinematic matrix, sector-by-sector factors of safety, optimization, and the methodology with the references behind each calculation. - PDF for sending and archiving - Editable Word, to fold into your own text - Excel with the result tables - In the interface language, with your project identification ## Every result comes from an established formulation. The toppling models were checked case by case against reference commercial software; the other modes follow established limit-equilibrium formulations. ## Your engineering data stays yours. - **Per-user isolation** — In the database.

It assesses rock slope stability from structural mapping data. From a single file it produces the stereonet with automatic set identification, the sector-based kinematic analysis, the factor-of-safety calculation across four failure modes and the face-angle optimization. ### What file format should I upload? .csv, .xlsx or .xls, with at least the dipdir and dip columns. 10 MB maximum. ### Do I have to save manually? There is no save button. Parameters and results are written automatically, and a project reopens exactly where you left it. ### Can I compare scenarios? Yes. Create scenarios inside one project, or duplicate the project, and compare results side by side. ### Which languages is it available in? Interface and reports in English, Portuguese and Spanish. ### Is my data secure? Per-user isolation, encrypted transport, private storage and an audit trail. We do not sell or repurpose your engineering data. ### How do I cancel? Through the Stripe portal, any time. Access remains until the end of the paid period, and cancelling does not delete your account or projects. ### Are the calculations validated? The toppling models were checked case by case against reference commercial software; the other modes follow established limit-equilibrium formulations. ## Talk to the team. Questions about the methods, the Enterprise plan, billing, or a demo for your team — we reply within one business day. contact@rightslope.io ## Technical responsibility RightSlope is a tool to support professional judgement. The results depend on the quality of the input data and parameters and on the assumptions of the limit-equilibrium methods and kinematic tests. They do not replace the analysis and technical responsibility of a qualified geotechnical engineer. --- © 2026 RockAnalytica · RightSlope · [Terms of Use](https://app.rightslope.io/terms) · [Privacy Policy](https://app.rightslope.io/privacy) · [rockanalytica.ai](https://rockanalytica.ai)
