Current Survey Methods

Every land development project begins with a topographic survey. It is a fundamental planning tool that provides engineers and planners with a starting point. The purpose of a topographic survey is to identify and map the contours of the earth and any existing features.

They are as important in urban environments as they are in untouched wilderness because they provide information such as terrain elevation, gradient, area, boundary lines, and easements. All of this information determines the extent of work required and the eventual project cost.

Producing topographic surveys is usually a labor-intensive process involving a team of mapping professionals. Using bulky tripods, electronic rangefinders, total stations, and GPS equipment, professional surveyors must traverse challenging terrain and manually collect data points at locations across the site. This process can sometimes take several weeks, precluding feasibility studies and delaying construction. This translates into lost revenue and delayed returns.


Drone-Based Data Collection

Technological developments in the fields of autopilot systems and sensor integration mean drones are now powerful geotechnical tools. Drones are a cost-effective and more powerful alternative to light aircraft and helicopters for producing highly detailed maps.

Aerial Mapping Applications

  • Urban Planning
  • Construction and Excavation
  • Quarries and Mines
  • Cadastre and Land Registry
  • Forestry and Agriculture
  • Transport Planning
  • Flood Modeling
  • Cellular Network Planning


Unmanned aircraft flying several hundred feet above the ground are now capturing 3D geospatial data with an exponential increase in detail over traditional survey methods.


Benefits of Drone Based Mapping

  • Map large areas in a matter of days
  • Exponential increase in detail
  • Rapid feasibility studies
  • Drastically reduced man-hours
  • Reduce risk to survey personnel
  • Georeferenced maps

Drones are redefining the way survey and mapping professionals operate. Simplified data collection means energy can now be focused on data analysis and project planning rather than on the logistical challenge of surveying.
