Landslides are a major threat to rail networks, leading to track damage, service disruptions, and costly repairs.

Rail infrastructure plays a vital role in the global economy, connecting cities, moving goods, and providing efficient transportation. However, rail networks are increasingly susceptible to ground displacement and subsidence, which can lead to track misalignment, service disruptions, and costly maintenance. For rail stakeholders, addressing these issues is crucial to ensure safety, reliability, and operational efficiency. Image credit: Network Rail

Synthetic Aperture Radar (SAR) and optical data systems each offer unique benefits, but SAR holds several key advantages.

Extreme weather events are likely to become more frequent and severe. These events pose significant risks to infrastructure assets.

While both are integral components of satellite-based Earth observation, they serve distinct functions and operate on different...

Remote sensing technology, particularly Interferometric Synthetic Aperture Radar can be harnessed to provide predicted maintenance for rail.

Unlike traditional ground-based observations, remote sensing allows for large-scale, repetitive, and often non-invasive data collection.

More intense and frequent rainfall can lead to waterlogged soils and higher instances of flooding, compromising foundation integrity.

Can we use the power of satellite remote sensing to detect and mitigate the risk of sinkholes?

In March 2024, a landslip occurred beneath a stretch of railway between Shrewsbury and Wolverhampton, UK.

Understanding the types of data that GIS handles can significantly enhance the ability to analyse and interpret spatial phenomena.

Many factors can cause a tailings dam to collapse from extreme weather to structural weakness, but what is the cost of a total failure?

When discussing ground movement and its potential hazards, landslides and subsidence often come up as two critical yet distinct...

In early May 2024, a section of the mountainside collapsed in China’s Guangdong Province, following many days of heavy rain. A 17.9m...

Hillside living offers stunning views and a serene environment, but it also comes with unique engineering consideration. As climate...

Resolution in remote sensing refers to the level of detail that a satellite sensor can capture in its imagery. It is a critical aspect of...

Subsidence is the gradual sinking or settling of the ground surface, often resulting from natural processes or human activities.

Understanding Subsidence Subsidence is the gradual sinking or settling of the Earth's surface. Human activities and climate change have...

Track movement, whether due to subsidence, ground instability, or other geological factors, poses a persistent threat to rail infrastructure

In today’s rapidly changing climate landscape, the threats posed by geohazards are becoming increasingly pronounced and complex. But what...
