Satellite Imagery & Elevation Data

2010 07 Jul - Mississippi Delta_828x200 banner image

Address real-world challenges with comprehensive geospatial intelligence for projects and operations located in different terrain, environments and climatic zones.

  • Over 40 years’ experience offering independent advice on satellite imagery and services
  • Source, process and analyze a fully comprehensive range of satellite imagery and elevation data worldwide. 
  • Improves understanding of landforms, infrastructure, land cover and the setting of activities, whether onshore, offshore or in transition zones.
  • Enables monitoring of local to regional changes, over periods from days to decades.

We acquire, process, interpret and distribute data from a wide range of optical and radar satellite imaging systems. Our long-standing links with satellite operators and our 'vendor neutral' position mean that we are best placed to identify the optimal satellite data to match the scope, budget and timescale of projects across the world.

Optical imagery

We supply and add value to satellite data from sensors that record visible and infrared imagery with ground resolutions of 0.5m to 30m. The images below depict the maximum spatial resolution of the imagery. The image captions describe the resolution range and operating lifespan of the satellite:
