Pipeline Corridor Status
Image credit: C-CORE
Pipeline corridor products are based on synthetic aperture radar (SAR) or optical satellite data and can be delivered on a complete pipeline network scale. Products are generated based on multi-temporal images and change detection.
The main driver for this product is typically a regulatory compliance monitoring requirement to report on the pipeline right of way (RoW) status on a periodic (e.g., monthly) basis. Indicators of interest include urban sprawl, vegetation cover, standing water, and other indicators that would require some maintenance or corrective action such as clearing.
While broad land cover changes can be detected with fairly coarse EO data (e.g., 30 m Landsat-8), high resolution data is desirable (5 m or better).
The pipeline corridor status product delivers land cover change detection along the pipeline corridor RoW. Areas of change can be provided (vector polygons), including reporting documents.
Known restrictions / limitations
Lifecycle stage and demand
Development: Critical historical information for planning and design of infrastructure, to support understanding of geographic conditions and risks in a proposed development area.
Production: Information on potential hazards in remote locations such as geohazards or vegetation succession, water courses, erosion, etc.
Decommissioning: Monitoring of land cover changes in support of reclamation and remediation compliance.
Geographic coverage and demand
Demand and coverage is global, applicable to any areas with pipeline networks.

Input data sources
Optical: VHR1, VHR2, HR1
Radar: VHR1, VHR2, HR1
Spatial resolution and coverage
Spatial resolution: 1–10 m
Varies depending on input imagery used and client needs. In case of radar images speckle effects may reduce the final resolution of images.
Coverage is typically 2 km to 3 km, plus expanded zones of influence of the pipeline route, and follows the pipeline RoW.
Minimum Mapping Unit (MMU)
Variable, depending on source data resolution, assumed scale of the final product and expected minimum size of the area monitored.
Accuracy / constraints
Thematic accuracy: 80-90%.
Spatial accuracy: depending on source data, typically 1 pixel.
Accuracy assessment approach & quality control measures
Ground-based or aerial validation.
Frequency / timeliness
Observation frequency: Depending on sensor and beam mode (resolution/extent) selected, the frequency for new acquisitions can be as low as 3-5 days from the same satellite. Frequency of historical maps is highly variable depending on the archive.
Timeliness of delivery: Product delivery is a periodic report on the status of the indicators monitored along the pipeline route. This is dependent on regulatory requirements, but is typically monthly.
On-demand availability from commercial suppliers.
New acquisitions can be requested globally.
Archived products available for public search. Availability may be limited for specific dates.
