High accuracy mapping for infrastructure and urban intelligence

High resolution satellite imagery offers the ability to rapidly produce accurate mapping.  Frequent updates to existing information and acquiring new mapping information offers benefits of continual and repeatable coverage, the ideal choice for accurate large area surveys for:
 
  • Assessing rainwater runoff, soil sealing and flood risk
  • Planning infrastructure and public services
  • Monitoring planning controls and identifying unplanned developments
  • Estimating population figures and growth

Land use classification

Space data using all spectral bands enables the characterisation of land into categories, which can be monitored for change detection, planning and resource management.

Natural resource management

Natural resources can be scarce, unpredictable, difficult to locate and difficult to manage and are under ever increasing pressure.  Significant economic, social and environmental benefits can be realised by using satellite systems to help manage available natural resources and to help locate new sources.Satellite data can provide change detection, monitoring and analysis of:

  • Coastlines and tidal plains
  • Sediments
  • Inland water resources
  • Wetlands
  • Glaciers, ice fields and snow cover
  • Desert
  • Mining activities
  • Oil and gas operations
  • Forest species inventories
  • Burn scars
  • Geological structure and mineralisation

Agriculture

Data from satellites can improve revenue generation for agricultural applications by improving crop yields, reducing fertiser costs, monitoring pests, and providing irrigation and field boundary information.  Agricultural management benefits from rapid revisit and wide area coverage.

Forestry management

Wide area imagery from satellites is the most efficient way to accurately and regularly monitor vast areas of forest - the tropics alone make up half of the Earth's land area, and many areas cannot be reached on foot.  More than one billion people are dependent on forests for their livelihood and forests also play a vital role in regulating our climate. High resolution imagery can be used to complement wide area lower resolution imagery.  

Satellite data can be used for:

  • De-forestation, re-forestation and afforestation tracking
  • Fire damage detection and burn scar mapping
  • Change detection
  • Supporting carbon modelling
  • Forest species inventory, stand density and health evaluation
  • Mapping of conservation areas and land tenure boundaries

Continuous coverage of wide areas, combined with high resolution surveillance of specific locations, provides an invaluable source of strategic information to complement the resources available for security and surveillance applications.
 

  • Pipeline monitoring
  • Critical national infrastructure mapping
  • Transport network tracking
  • Operational support and mission planning 
  • Analysis and monitoring of key sites and assets

Maritime services

 


 
  • Ship detection and tracking
  • Maritime oil spill detection and monitoring
  • Ice warnings
  • Oil slick monitoring
  • Port traffic monitoring
  • Bathymetic data to measure beach erosion, sea levels, creation of nautical charts
  • Maritime piracy detection

Disaster Monitoring

Disaster monitoring activities are undertaken by many nations and in particular by the Disaster Monitoring Constellation of satellites supplied by SSTL.  Undertaken on behalf of society worldwide, this service provides an important source of humanitarian information as well as a framework for international collaboration.

Satellite data provides georeferenced regular snapshots, which can be used in conjuction with flood and soil models, digital elevation models, precipation data, and population statistics to produce a base map for emergency services in the event of flood, fire, drought, earthquake, hurricane, tsunami, tornado and other natural and man-made disasters.  Disaster information from satellites is rapidly available and accurate and is often the only overview available to guide and plan emergency assistance.
