Acquisition date: July 2020
Objective: Create a cut and fill study to develop a park according to a proposed development plan
Surface area: over 7 hectares
Data precision: +/- 4cm
Cost of project: 2 500$

Tools used:

  • DJI phantom 4 pro drone
  • Tersus bi-phase GPS (control points)

Softwares used: 

  • Global mapper – Level curves generation 
  • Agisoft Metashape – Photogrammetry 
  • 3D civil Autocad – Cut and fill data generation 

Methodology used – workflow: 

  • GPS ground control points 
  • Data processing of drone images by autocorrelation with Agisoft Metashape software and creation of the orthoimage 
  • Level curves generation with Global Mapper software 
  • Use of the project’s projected level curves and the existing ones in the 3D civil 
  • Autocad software and generation of cut and fill data 
  • Data mapping (orthoimage and level curves)
