Unlocking the power of NISAR

How Advanced Radar Technology is Transforming Geohazard and Infrastructure Monitoring

We’re excited to share that 3vGeomatics (3vG), a key part of Orica Digital Solutions’ Geosolutions portfolio, is enhancing its ground movement monitoring service by integrating data from the NISAR NASA-ISRO SAR satellite. By leveraging NISAR’s advanced radar capabilities, we now deliver more reliable, cost-effective insights, especially in remote and vegetated areas. Here’s a closer look at the technology behind it.  

How does NISAR work? 

NISAR (NASA–ISRO Synthetic Aperture Radar) is the first satellite mission to use dual radar frequencies: L-band and S-band, to systematically map Earth’s surface. Its L-band radar, with a longer wavelength (~240 mm), penetrates vegetation, where traditional SAR data struggle. The S-band radar is currently used for targeted applications in India.

Why is this a game-changer for geohazard monitoring?

• Large Image Footprints: Cover extensive land areas (excluding oceans) with uniform resolution. 
• 12-Day Revisit Cycle: Offers regular updates for timely monitoring 
• Open Data Policy: Raw SAR imagery is freely available; 3vG processes it into actionable InSAR insights.

What problems does NISAR solve?

NISAR directly addresses key challenges faced by infrastructure operators across mining, energy, transport, and government sectors:

Risk Management

• Detect ground movement early
• Monitor infrastructure at scale
• Respond faster to geohazards
• Meet regulatory requirements

Monitoring in Vegetated and Remote Areas

• L-band radar penetrates vegetation
• Enables reliable tracking in areas previously inaccessible to traditional InSAR

Scalable Network Monitoring

• NISAR’s global reach and revisit cycle allow affordable monitoring of entire networks, including pipelines, railways, roads, and power distribution networks.

Timely Insights

• Integrated with 3vG’s advanced processing platforms
• Delivers near real-time data for faster, more informed decisions

Why it matters?

3vG’s NISAR-powered service makes it easier and more cost-effective to monitor ground movement, regardless of the location of your assets. From dense forests to remote terrain, it delivers reliable insights at scale.

What that means for you:

• Fast, regular updates to detect risks early
• Coverage across entire networks, including pipelines, roads and railways
• Reliable monitoring in harsh environments, including vegetated slopes, remote sites, and long infrastructure corridors.
