TIN surface, commonly produced by GPS Rover and Total Station equipment (for example, in an exported DXF file) are key to integrating ground-based survey data into the Propeller platform.
TIN surfaces support all core features for measuring and tracking earthworks. This enables users to:
- Compare surveyed terrain with design plans.
- Perform volume calculations for cut/fill analysis.
- Visualize and analyze changes over time.
They can also patch drone surveys or create composite surveys in areas with vegetation or water, enhancing accuracy.
Uploading a TIN Surface
Click the UPLOAD button at the top-right corner. Under the PRE-PROCESSED section, select Surveys and then TIN Surface.
Navigate to or drag and drop your files into the TIN Surface window.
Choose whether to add it to a composite survey or hide it. Hidden surveys will not appear in the Survey drop-down. Click SUBMIT.
By default, Hide from Survey Picker is enabled, but you can still access the survey by selecting Show hidden in the survey picker.
The option to Add survey/s to Composite is only available when a composite is currently selected in the survey picker.
You’ll receive a confirmation that the TIN surface was uploaded successfully.
You can navigate to the TIN survey by selecting it in the survey chooser.
Alternatively, you can view and merge the TIN survey to patch an existing drone survey or build a larger composite from multiple captures.
If the Hide from Survey Picker option was selected, the survey will not appear in the list by default. To view it, enable the Show All toggle.
When this survey is opened through the survey picker, it will display an elevation heatmap by default, similar to other non-imagery surveys.
Additionally, the TIN Surface layer can be toggled on as needed.
