Case Study:

National Surveys of Land Subsidence

Terra Motion have been generating national maps of subsidence using Sentinel-1 data since 2018, when our UK product gained international attention.  Our average motion product of the Netherlands was one of the first country-wide surveys to be subject to academic peer review and was used by the Rijkswaterstraat as a layer in the Dutch national climate atlas.

We are able to perform complete national and regional surveys of subsidence at any location across the world using Sentinel-1 data.  Our standard surveys are performed at 20m resolution and provide near 100% coverage over all urban and rural land cover types.  No ground infrastructure, such as corner reflectors or CGPS networks, are required although the results can be easily adjusted if geodetic control is needed.

National and regional APSIS© products are able to support a full range of environmental applications such as:

  • Providing a complete evidence-based directory of natural perils for the insurance market

  • Proof of adherence to international climate change targets

  • Identifying increasingly flood-prone areas threatened by rising sea levels

  • Regulation of active and abandoned mining and oil & gas sites

  • Monitoring landslides in severe terrain

  • Locating problems and threats across entire transport and energy infrastructure networks

 

Since 2018, we have placed low-resolution (90m) versions of our maps on the internet where anyone can browse them, for free.  Please access the browsable versions by clicking on the flags below.
