Key Takeaways

  • Photogrammetric structural mapping — extracting discontinuity orientation, spacing, and trace length from pit-wall imagery — is the established standard, via Maptek’s I-Site Studio/PointStudio and the CSIRO-developed Sirovision system.
  • Automated discontinuity-detection algorithms are increasingly built into these platforms, reducing manual digitizing of joint sets from point clouds.
  • This is a commercial, deployed capability, with the AI/automation layer still emerging on top of an already-mature photogrammetry foundation.

TL;DR

AI-assisted structural mapping means capturing pit-wall point clouds via laser scan or drone photogrammetry in Maptek PointStudio (or CSIRO’s Sirovision), then using increasingly automated discontinuity-detection algorithms to extract joint orientation, spacing, and trace length instead of hand-digitizing every structure.

How Do I Apply AI to Structural Mapping?

Structural mapping — recording the orientation, spacing, and persistence of joints, faults, and other discontinuities across a pit wall — has been transformed by photogrammetry over the last decade, and that’s the foundation any AI layer sits on top of. Maptek’s PointStudio (formerly I-Site Studio) turns terrestrial laser scans and drone photogrammetry into point clouds, then provides geotechnical tools for plane fitting, discontinuity set analysis, and slope evaluation directly from that data — no manual tape-and-compass scanline survey required. CSIRO’s Sirovision system, widely deployed through consultancies like SRK, does the equivalent for bench-scale kinematic analysis, capturing 3D location, orientation, trace length, and fracture spacing from stereo photogrammetric pairs.

The emerging piece is automated discontinuity detection: rather than a geotechnical engineer manually clicking and fitting planes to visible joint traces in the point cloud, newer algorithms increasingly automate that extraction, flagging candidate discontinuity sets for review instead of requiring fully manual digitizing. This is a genuine productivity gain layered on genuinely mature photogrammetric hardware and software — you’re not waiting for the core technology to mature, just adopting the automation features as they roll out in tool updates.

Try It With Geocluster

Connecting structural mapping output to your block model and slope-design inputs — so a newly mapped joint set actually updates downstream geotechnical models — is the kind of integration work Geocluster is built to support.
