Landform Shape-Disparity Analyzer

A software add-on that applies biological shape-analysis methods (landmark-based Procrustes analysis) to landforms such as river meanders and landslide scarps, giving geologists and river engineers a rigorous way to measure and compare how terrain shapes vary and change.

Concept

Landform Shape-Disparity Analyzer is a software add-on (an R package or ArcGIS plug-in) that brings geometric morphometrics — the landmark-based Procrustes toolkit long used in biology — to physical geography. Users extract landform outlines from digital elevation models (river meander planforms, landslide scarps, dune fields, volcanic edifices), place landmarks, and run Procrustes superimposition, shape-disparity, and modularity tests to quantify how landform shapes vary across sites or through time. Concrete uses: tracking meander migration before and after river restoration, or comparing scarp geometries between stable and failing slopes. The wedge: rigorous, reproducible shape statistics for terrain features that today are compared by eye or with ad-hoc metrics.

Why now

The methods are mature and open: [1] delivers the open-source geomorph package for Procrustes-based shape analysis, and [2] establishes that integration and modularity analysis applies at multiple levels of variation (within populations, across environments, through time). The new paper [0] confirms geomorphology is an active, peer-reviewed domain with a dedicated venue (JGRP explicitly covers geomorphology) — but the morphometric machinery has never been packaged for terrain applications, leaving a clear tooling gap for hazard and river-restoration professionals.

A focused application of existing biological morphometrics to geomorphology that solves a real pain point in terrain analysis with a clear, implementable wedge.

Evidence strength
4/5
The idea relies on the well-established 'geomorph' R package and the mathematical validity of Procrustes analysis, which is directly transferable to coordinate-based landform data.
Market pull
3/5
While the beneficiaries (USGS, Deltares) have a clear need for rigorous metrics, the market is a niche professional segment rather than a mass-market opportunity.
Novelty & moat
3/5
While the underlying math is identical to the 'Comparative Morphological Mapping Tool', applying it to non-biological landforms creates a distinct value proposition and user base.
Feasibility
5/5
The core engine already exists as an open-source R package; the MVP is essentially a wrapper/plugin for ArcGIS or a specialized R workflow.
Wedge clarity
4/5
The focus on river meander migration and landslide scarp geometry provides a sharp, specific entry point for geomorphology consultants.
Simplicity / focus
5/5
The product is a single-purpose analysis tool with a clear function, avoiding the 'platform' trap.

Who benefits

  • U.S. Geological Surveyorganization

    USGS studies landslide and river processes; Procrustes-based shape statistics on scarp and channel outlines would give its geomorphologists a reproducible way to quantify landform change.

  • Deltaresorganization

    The institute's river-morphology and flood-risk teams could use meander planform disparity metrics to monitor channel evolution and evaluate restoration designs.

  • Inter-Fluvecompany

    The river-restoration design firm needs before/after evidence of channel change; quantified shape-disparity comparisons would strengthen its design reports for clients.

  • British Geological Surveyorganization

    BGS geohazard teams assess slope failure; comparing scarp geometries between stable and failing slopes with modularity tests adds a measurement relevant to early warning.

  • Esricompany

    As the dominant GIS platform vendor, Esri could bundle terrain morphometrics as an ArcGIS Pro capability, differentiating its geoscience offering.
