Workflow Overview
Our process begins with capturing high-resolution aerial imagery using drone platforms. The collected images are processed through photogrammetry software such as DJI Terra or RealityCapture to generate accurate Digital Surface Models (DSMs) and orthomosaics. These outputs serve as the foundation for volumetric analysis.

The DSMs and orthomosaics are then imported into Virtual Surveyor, where we define precise boundaries around areas of interest—such as stockpiles, excavation sites, or grading zones. By establishing these boundaries, we can perform detailed volume calculations and generate cut/fill reports that are essential for project planning and management.

Analysis & Methodology
We employ two primary methods for volumetric calculations:

• Base Plane Method: Ideal for isolated stockpiles, this approach involves defining a flat reference plane beneath the pile to calculate the volume above it.
  
• Cut/Fill Method: Used for construction sites and grading areas, this method compares the current terrain surface to a design or previous surface to determine the volume of material to be cut or filled.
  

These methods provide:

• Cut Volume: Material to be excavated.
  
• Fill Volume: Material required to achieve the desired grade.
  
• Net Volume: The difference between cut and fill volumes.
  
• Surface Area: The area over which the cut/fill operations occur.
  

Software Tools Utilized

• DJI Terra / RealityCapture: For generating DSMs and orthomosaics from drone imagery.
  
• Virtual Surveyor: For defining boundaries, calculating volumes, and generating cut/fill maps.
  
• QGIS (Optional): For advanced spatial analysis and visualization, if required by the project.
  

Deliverables & File Formats
We provide comprehensive deliverables tailored to your project's needs:

• PDF Reports: Detailed volume calculations, including cut, fill, net volumes, and surface areas.
  
• CAD Files: DXF or DWG files compatible with AutoCAD and other design software.
  
• GIS Files: SHP or GeoTIFF files for integration with GIS platforms like ArcGIS or QGIS.
  
• CSV Files: Tabulated data for easy import into spreadsheets or project management tools.
  

Applications & Use Cases
Our volume analysis and cut/fill reports are applicable across various sectors:

• Construction: For site grading, excavation planning, and progress tracking.
  
• Mining & Quarrying: To monitor stockpile volumes and manage resource extraction.
  
• Land Development: Assisting in planning and verifying earthworks for residential or commercial projects.
  
• Environmental Management: Monitoring changes in terrain for conservation or restoration efforts.
  

Accuracy & Limitations
Our volumetric analyses are based on photogrammetric data and are suitable for planning and monitoring purposes. While we strive for high accuracy, factors such as vegetation cover, surface texture, and image quality can affect results. For projects requiring survey-grade precision, we recommend incorporating Ground Control Points (GCPs) or using RTK-enabled drones to enhance accuracy.
