InSAR Analysis and Corner Reflector Experiments for Infrastructure Stability Monitoring Using Sentinel-1 Imagery
National Grid Energy Transmissions (NGET), which owns and maintains the high-voltage electricity transmission network in England and Wales, conducts invasive analysis annually to monitor the towers most at risk of movement. Moreover, the NGET inspection teams perform annual line walking activities and monthly substation inspections during which they visually assess the presence of asset motion. These interventions are crucial to avoid issues which may cause expensive assets replacements or reconstruction. It costs NGET over £6 million per year to monitor only 1% of their most at risk assets.
The operation of oil and gas transmission pipelines entails inherent risks associated with the potential for unintentional product releases. Oil and gas product releases have traditionally been treated as safety issues due to the risk of explosions and asphyxiation, but increasingly, the environmental impact of unintentional product releases is fast becoming the key risk to be reduced and avoided via Leak Detection and Repair (LDAR) programs.
Spottitt is known for utilising satellite data to offer infrastructure owners valuable insights into the diverse external risks affecting their assets. But how precisely do we derive these insights from satellite imagery? The answer is – machine learning, and today we’re inviting you behind the curtains of our product to unveil the whole process.
As more organizations turned to Spottitt for monitoring growing numbers of assets, we recognized that the traditional geospatial platform’s map view, which was effective for small-scale monitoring, became cumbersome when dealing with larger datasets. So, we embarked on the development of Spottitt Metrics Factory. Since its beta launch in late 2022, ten organizations from around the world have been delighting in the ability to view and interact with their asset monitoring data using the product.
In this piece, we delve into the realm of satellite technology, focusing on the determination of vegetation height and the planning of routes for electrical distribution lines.
Additionally, we examine the algorithm that empowers open-source meters in resolution SAR sensors to measure millimeters per year of land or asset motion. We also provide an overview of the driving forces behind the application of satellite technology for monitoring methane and other greenhouse gases.
Today, we’re going to address common myths and misconceptions surrounding satellite data and analytics. These are questions that have frequently come up from both our clients and prospects. Our aim is to provide clarity and assist you in understanding whether satellite-based asset monitoring is something you should consider for your organization.
