Features
What terrain intelligence looks like
Terrain-masked camera coverage
Coverage cones respect real elevation data. Ridgelines, slopes, and buildings block the field of view — just like the real world.
DORI zone analysis
Detect, Observe, Recognise, Identify zones calculated from sensor physics — not hardcoded distances.
Drone LOS analysis
Green where clear, red where blocked. See every obstruction between observer and drone before the field day.
Multi-camera overlap
Detect overlapping coverage between cameras. Verify redundancy and identify single-point-of-failure zones.
Terrain elevation profiles
Cross-section views showing ground elevation vs line-of-sight. Identify the exact ridge that blocks your coverage.
Professional exports
PDF reports, KML for Google Earth, GeoJSON, CSV, and PNG. Every format your clients and regulators expect.
Two modes
One platform. Every coverage scenario.

Deep Dive
Built on real terrain data
Every metre of elevation changes the coverage
Flat-plan tools assume a bowling-green site. SighThor pulls real terrain elevation and raycasts through it — ridgelines block coverage cones just like they block cameras in the field. What you see on screen is what your cameras see on site.
Resolution: sub-2m · Source: Mapbox Terrain-DEM v1DORI zones calculated from real sensor physics
Detection, Observation, Recognition, Identification zones derived from your camera’s actual sensor dimensions, focal length, and resolution — not hardcoded distances. Compliant with IEC 62676-4 and the new OODPCVS framework.
PPM = resolution_h / (2 × distance × tan(hFOV/2))
See blocked segments before the field day
Every point along your drone route is checked for line-of-sight from each observer position. Terrain obstructions, Fresnel zone clearance, and earth curvature are all factored in. Green where clear, red where blocked.
Clearance bands: Blocked · Poor · Marginal · Good · Excellent
Export evidence, not screenshots
Generate approval-grade PDF reports with your client’s branding, KML files for Google Earth, GeoJSON for GIS tools, and CSV for spreadsheets. Every export includes the data regulators and clients expect.

Compliance
Built for regulatory compliance
SighThor exports are designed for regulatory submissions. PDF reports, KML overlays, and GeoJSON datasets include the metadata auditors and authorities expect, so your planning documentation is submission-ready from day one.
