Elevation + High precision digital elevation modelling service

Elevation+ Cornish Quarry
  
Elevation+ offers airborne based elevation surveys around the world providing 1 m or better resolution. Alongside our satellite technologies, we also own and operate airborne sensors. LiDAR  data is the most cost-effective, accurate height data in production from airborne systems, with the ability to generate accurate terrain models.

Our laser scanning expertise and experience has been developed by undertaking a wide range of projects, in diverse environments such as the eserts and jungles of Africa and Asia, the coast line of the British Isles and cities across the world.

Digital Surface Models (“first surface” elevation) and Digital Terrain Models (bare earth elevation) products are available with the option of accompanying orthophotos. The orthophotos can be derived from the strength of the laser return, commonly referred to as laser intensity or from the use of an optional camera.

Elevation+ Key Benefits:

  • Highly detailed height data with horizontal spacing of 1 m or better

  • Vertical accuracy of 20 cm LE90

  • Rapid acquisition and processing

  • Day and night operation

  • Canopy penetration

1 m DEM for developing a new road scheme

Applications

Airborne based LiDAR surveys are ideal for high precision requirements as part of demanding projects such as:

  • Engineering design phase
  • Overland flow flood modelling
  • Pipeline routing.
  • Quarry extraction monitoring
  • Coastal erosion monitoring
  • Telecommunication cell network planning
When fitted to an aircraft, the LiDAR system is flown over an area along overlapping strips until the complete area of interest is covered by the laser points. The use of high accuracy GPS positioning and inertial altitude measuring instruments, together with powerful computing software allow very accurate models to be produced.
