FAQs About Earthwork Surveys

We answer the most common questions about drone-based cut/fill mapping and deliverables.

What does your earthwork analysis include?

Our process analyzes terrain changes using differential layers and elevation data.

Is your data compatible with civil and GIS platforms?

Yes. Our spatial references are structured to support common workflows in design and planning environments, including those used in civil and GIS contexts.

How is surface change measured during earthwork analysis?

Surface variation is typically analyzed with a vertical resolution of ≤3 cm when using RTK/PPK and GCP workflows. This supports layout review and grading interpretation.
