Illegal Mining Activity Intelligence in Ghana
In ProgressOngoing geospatial monitoring to identify and track illegal mining hotspots across high-risk zones in Ghana.
Challenge
Field agencies needed timely visibility into expanding illegal mining footprints, river contamination risk, and repeated activity in remote locations.
Solution
Subterra is deploying a continuous intelligence workflow combining high-frequency satellite imagery, terrain change detection, and GIS enforcement layers into one operational dashboard.
Data Streams
- Optical satellite imagery
- Terrain change analytics
- Hydrology and watershed layers
- Field incident records
Impact
Improved hotspot detection for enforcement planningEarlier environmental risk flagging in affected watershedsStructured weekly intelligence updates for stakeholders
Energy & Utilities
Transmission Corridor Encroachment Intelligence
Persistent monitoring of right-of-way and vegetation threats along transmission assets.
Challenge
A utility operator needed earlier visibility of corridor encroachment and vegetation growth before it affected reliability.
Solution
We fused drone capture, periodic imagery refresh, and GIS asset layers for corridor change detection and risk-priority tasking.
Data Streams
- Drone imagery
- Satellite basemap updates
- GIS asset layers
- Inspection history
Impact
Improved maintenance prioritizationReduced inspection blind spotsShorter response cycles for field teams
Infrastructure Delivery
Construction Progress Assurance Program
Decision-ready progress intelligence across distributed construction sites.
Challenge
Program managers struggled to verify schedule progress and volumetric changes consistently across multiple contractors.
Solution
Subterra implemented a recurring capture-to-dashboard flow with orthomosaic delivery, 3D surfaces, and milestone-based analytics.
Data Streams
- Orthomosaic imagery
- 3D terrain models
- Survey control data
- Milestone schedule records
Impact
Trusted progress evidence for stakeholdersImproved contractor accountabilityBetter cost and schedule control
