Terms of Service
Effective date: September 19, 2026. Please read these terms carefully before utilizing our geographic instruments.
1. Informational & Educational Use Only
CRITICAL LEGAL & SURVEYING DISCLAIMER
Open Map Lab provides geographic calculations, boundary approximations, and elevation lookups for general reference, travel, education, and planning only. Do not use this website for life-critical navigation, maritime pilotage, aviation flight planning, professional land surveying, official property boundary disputes, voting district appeals, or emergency 911 dispatch.
2. Accuracy & Limitation of Liability
While we rigorously test all algorithms and source our boundaries from official federal agencies (US Census Bureau, Copernicus GLO-90 DEM, IANA), geographic boundaries and GPS signals are subject to physical uncertainty, atmospheric refraction, satellite drift, and local legislative revisions. Open Map Lab is provided "as is" without warranty of any kind.
3. Intellectual Property & Open Data
Our web software, user interface design, and original editorial analyses are copyright © Open Map Lab. Our underlying spatial boundaries and public datasets remain in the public domain or under the Open Database License (ODbL).
