Active Volume Layer

In the context of the Volume tab of the ribbon and the Volumetric Analysis workflow in LP360, a volume layer refers to a specialized feature layer that stores the results of volumetric computations—such as cut, fill, and total volume values—generated by the Volumetric Analysis Point Cloud Task (PCT).

🧭 What Is a Volume Layer?

A volume layer is a shapefile or feature layer that contains the computed volume attributes for each defined area (e.g., stockpile, pit, basin). It is created when you run the volumetric analysis and is used to:

• Store and visualize volume results.
• Enable review and editing in Feature Analyst .
• Support downstream workflows like reporting, QA/QC, and product generation.

This layer is distinct from the Active Area Layer, which defines the boundary (toe) of the feature being measured.

📌 Role in the Volume Tab Workflow

In the Volume tab of the LP360 ribbon:

• The Compute Volume allows users to define settings and execute the volumetric task.
• Upon execution, the results are saved to the Active Volume Layer, typically named something like adjusted_toe_volumes.shp.
• The volume layer is automatically added to the map as the Active Volume Layer unless the user disables this in the Volumetric Workflow Settings .
• After running the volumetric task, the Active Volume Layer can be opened in Feature Analyst for review by using the Review Volume Features tool on the on the Volume tab.

📊 What’s Inside a Volume Layer?

Each feature in the volume layer includes:

• Cut Volume
• Fill Volume
• Total Volume
• Surface Area
• Min/Max Elevation
• Optional diagnostic attributes (if enabled)

These attributes are calculated based on the difference between the base surface (defined by the area layer) and the hull surface (typically derived from LAS points).
