Frequently Asked Questions

How accurate is GPS measurement for construction site surveys?

Modern smartphone GPS provides accuracy of 3-5 meters - sufficient for bids, material estimates, and preliminary boundary documentation. For legal boundary surveys or permits, a licensed surveyor is still recommended.

Can I calculate material quantities like concrete and asphalt directly from measurements?

Yes. Once you've measured a site's area, LandLens converts square footage into concrete volume, asphalt tonnage, fencing length, and other material quantities so you can bid jobs accurately on the spot.

Does LandLens replace the need for a professional land surveyor?

No. LandLens is built for fast, low-cost site surveys, bids, and material planning. For legal property boundaries, permits, or disputes, you'll still need a licensed surveyor.

Can I export site data for permits or CAD software?

Yes, export your measurements as KML, GeoJSON, Shapefile, or PDF. These formats are compatible with most CAD and GIS software, and PDF reports can be shared directly with clients or subcontractors.
