Common questions
Can I use the results for professional deliverables?
Verify the inputs, reference systems and assumptions independently. These utilities provide general estimates and checks, and do not replace professional surveying workflows.
Is my data uploaded?
No. Tool inputs and file contents are processed locally in your browser. The area tool fetches public map tiles from OpenStreetMap.
