Historic Mining Intelligence
See How Your Mine Has Changed Over Time
Transform decades of aerial photography into orthophotos, terrain models, 3D surfaces and vector data that reveal the evolution of your mine.
Whether you're reopening historic workings, planning expansion, managing rehabilitation or investigating stability, our historic aerial archive and specialist photogrammetry services provide the evidence needed to make informed decisions.
Use cases include:
-
Reconstruction of pre-mining topography
-
Historical volume and landform calculations
-
Environmental and resource consent work
-
Supporting evidence for land disturbance assessments
-
Rehabilitation and mine closure planning
-
Legacy and abandoned mine investigations
-
Historical environmental conditions
"The historic imagery shows many of the mine sites totally devoid of any tree / vegetation cover whereas today most of those sites are completely covered by dense forest cover."
John Taylor - Mining Geologist
Historic Film Scanning
Preserve and unlock your aerial archive.
Historic aerial film is scanned using high-resolution photogrammetric scanners, creating digital imagery suitable for engineering and GIS workflows.
Benefits
-
Ultra-high resolution scanning
-
Colour and black & white film
-
Georeferencing available
-
Long-term digital preservation
-
Suitable for photogrammetric processing
Historic Othophotos
Accurate imagery from the past.
Historic photographs are processed into geospatially accurate orthophotos, allowing direct comparison with modern imagery.
Applications
-
Mine expansion history
-
Rehabilitation monitoring
-
Historical infrastructure mapping
-
Environmental baseline studies
-
Lease boundary investigations
-
Tailings storage monitoring
Historic Terrain Models (DTM)
Reconstruct historic terrain.
Using stereoscopic aerial photography, we can recreate historical ground surfaces that no longer exist.
Ideal for
-
Pre-mining terrain reconstruction
-
Cut and fill calculations
-
Subsidence analysis
-
Pit volume estimation
-
Rehabilitation assessment
-
Flood modelling
Historic 3d Models
Explore the past in three dimensions.
Historic stereo imagery can be transformed into textured 3D meshes, allowing teams to virtually inspect sites exactly as they appeared decades ago.
Perfect for
-
Planning mine extensions
-
Engineering reviews
-
Community consultation
-
Historical investigations
-
Virtual site inspections
