USGS Elevation Web Service is available to the general public online, at no cost. 2) ***The initial view of this app requires a GPS signal to work properly. A clear view of the sky is needed for GPS reception, and it may take several seconds to get a position fix. Elevation for Real will run on devices not equipped with a GPS receiver and GPS-equipped devices that are not receiving a GPS signal, but any resulting elevation readings will just be the approximate ground elevation at your location, even if you are several stories up in a tall building. 3) ***Any elevation measurements with personal safety or financial implications should be performed by professionals with professional GPS equipment. Elevation for Real is not intended to determine flood hazard. Consult a licensed professional in your jurisdiction, such as a surveyor or engineer, when dealing with flood risk.
