Aerial Mapping

Powers & Tiltman can also offer aerial mapping, a fast growing concept in surveying based on flying a small remote control, light weight aircraft (or Unmanned Aerial Vehicle, UAV) with an on-board camera combined with GPS technology, across large areas of land.

Advances in technology surrounding these aircraft including the introduction of light weight digital cameras, practical lightweight lithium polymer batteries, low cost drone technology and advances in aerial oblique photography have significantly reduced the costs of mapping large scale tracts of land.  We provide high resolution imaging allowing us to analyse and extract highly detailed and accurate information whatever your requirements and at speed. 

Aerial mapping has many different uses and benefits, for example;

  • The ability to map large tracts of land over difficult terrain.
  • Reducing risks to health and safety by mapping hazardous areas without the need to enter the site on foot.
  • It’s a time efficient way of gathering data at speed on expanses of land.
  • There’s no need for multiple crews to go on site to get the job done, thereby reducing costs.
  • It provides information to make critical, up front decisions which could seriously impact upon your later decision making.

Typical surveys carried out by aerial mapping includes:

  • Topographic Surveys
  • Volumetric Surveys
  • Flood Risk Surveys
  • Landfill/Quarry Surveys
  • Route Surveys

Based on photogrammetric survey methods and combined GPS control points on the ground, survey data is processed to accuracy similar to lidar data. Once surveyed, our clients can choose to receive either a 3D digital terrain model (DTM) or 2D or 3D plan.

At Powers Tiltman we have a dynamic approach to Land Surveying ensuring our clients have access to the latest technological advances and providing an exceptional level of service.

Frequently Asked Questions:

  1. Is surveying using unmanned aerial vehicles as accurate as using traditional electronic /GPS survey methods?

    No, levels are not as accurate but can be within a tolerance of 40-50mm which may be sufficient for appraisal work.

  2. Can you map anywhere with UAV’s?

    You will need the land holder’s permission to fly UAV’s over their land.
