Birdi’s AI Detect – Stockpile tool automatically identifies stockpiles on your map, but volumes are not calculated by default. To generate volumetric results, detected stockpiles must be calculated against a selected Digital Elevation Model (DEM).

This article explains how to turn AI-detected stockpiles into a volumetric report that can be renamed, styled, exported, and used in reporting.

Before You Start

Ensure you have:

  • AI Detect – Stockpile results visible on your map

  • At least one processed DEM available in the project (e.g. DTM, DSM)

  • Stockpile annotations selected in Volumetric Mode

How to calculate volumes from AI-Detected stockpiles

1. Select the Stockpile Annotations

  • Hold Shift on your keyboard

  • Click to select all stockpile annotations you want to calculate

  • You will see the annotation count appear in the right-hand panel

2. Choose a Volume DEM

  • In the right-hand panel, locate Volume DEM

  • Select the DEM you want to calculate volumes against (e.g. site DTM)

💡 Tip: The accuracy of your volumes depends on the quality and relevance of the selected DEM.

3. Select a Base Calculation Method

Under Base method, choose how the base surface is defined. For example:

  • Linear Fit – commonly used for stockpiles on relatively even ground

4. Calculate Volumes

  • Click Calculate

  • Birdi will calculate the volume for each selected stockpile

  • Volume labels (m³) will appear directly on the map

After Calculation: What You Can Do Next

Once volumes are calculated, stockpile annotations can be:

  • Renamed - Update stockpile names for clearer identification (e.g. by material or location)

  • Styled - Change colours and visual styles to match reporting or classification needs

  • Used in Reports - Include calculated volumes directly in reporting workflows

  • Exported - Export volumetric data using Table View

Notes & Best Practices

  • Volumes are not automatically detected — calculation must be manually triggered

  • You can re-run calculations at any time using a different DEM or base method

  • Multiple stockpiles can be calculated in bulk using Shift-select
