Project Report: Calculating Stock-Pile Volumes Using Drone Sensors

1. Introduction

This project aims to calculate the volumes of Stock-piles using data collected from drones equipped with elevation sensors and Multispectral Sensors (MSS). The report details the methodology, data processing steps, and findings obtained through the analysis.

2. Objectives

The primary objectives of this project include:

• Utilizing drone technology to collect elevation and multispectral data.
• Processing collected data using Virtual Surveyor and QGIS software.
• Calculating the volumes of piles within the surveyed area.
• Visualizing and presenting the results effectively.

3. Methodology

This section outlines the step-by-step process followed in the project:

1. Data Collection: Drone flights were conducted to capture elevation data and multispectral imagery over the target area.
2. Data Processing: Imported collected data into Virtual Surveyor and generated digital surface models (DSMs) using elevation data. Processed multispectral imagery to extract relevant features affecting pile volumes.
3. Pile Volume Calculation: Defined pile boundaries using Virtual Surveyor, then calculated volumes by comparing pre-piling and post-piling surfaces within these boundaries.
4. Analysis and Visualization: Exported calculated volumes and related data to QGIS for visualization, enabling a clear representation of piles and their volumes.

4. Results

The findings and outcomes obtained from the project are summarized as follows:

• Volume Calculation: Calculated volumes of individual piles and total volume within the surveyed area.
• Visualization: Visual representations using QGIS showcasing pile distributions and their respective volumes.
• Accuracy and Limitations: Volume Accuracy assement stands 97% accurate for most of piles (sand like).
