The Takeoff Map is a professional tool used to track earthwork progress by comparing site surfaces. This feature generates a detailed visual cut and fill analysis, allowing for the calculation of material movement and the determination of work remaining to reach final grade. By utilizing various comparison types—including designs, previous surveys, or fixed reference levels—users can maintain precise control over site compliance and productivity.
Identify the area inside the map
Select the site and survey of interest from the dropdown menus within your project.
Navigate to the Outputs tab and select Takeoff Map within the MAPS section.
Adjust the grid boundaries by dragging the corners to cover the intended work area. The map can also be panned to center the grid.
Select comparison surfaces
Propeller's Takeoff Map allows for multiple comparison of different surfaces.
From surface: This defaults to the current survey.
-
To surface: Select the comparison target from the dropdown menu:
Designs: Compare the survey against a specific design grade.
Surveys: Compare two different surveys to see progress between dates.
Reference Surface: Enter a specific elevation (RL) to check ground height against a fixed limit or verify the highest and lowest elevation levels within the grid and select apply to update the map.
Set grid spacing: Choose the grid size for the report based on the scale of the site.
| 💡 Tip: Use the reference surface when verifying ground height against a maximum elevation ceiling—ideal for sites near no-fly zones. |
Customize visuals and layouts
Configuring visual settings ensures the report is readable and matches project documentation.
Configure the heat map: Adjust the color scheme and deadband (measurement increments) by selecting the color block. Select apply to update the preview.
Overlay contours: Specify minor and major contour intervals and colors (black or white) using the (
) icon for added topographical detail.
Set map orientation: Use the rotation tools to align the report with project north or true north to ensure consistency with construction drawings.
| 💡 Tip: For large sites, wider grid spacing or exporting smaller sub-sections will reduce processing time. |
Export the report
Once the configuration is verified, generate the document for distribution.
Select the paper size from the dropdown menu. Options include standard U.S. and international sizes up to A0.
Click export takeoff map.
Open the file. The PDF will automatically open in a new tab once rendering is complete.

Reading the takeoff map
The report is structured for rapid data retrieval in the field. Each grid square features a crosshair indicating the exact location where measurements were calculated.
| Report element | Description |
|---|---|
| Crosshairs | Indicates the specific cut, fill, and material moved for that grid location. |
| Area summary | Provides total cut, fill, and net volumes for the area within the selected grid (m/yd) |
| Site metadata | Lists site name, survey date, created date, created by. |
| Heatmap legend | Defines the color scale used to represent elevation changes. |
