The height above sea level is also referred to as elevation and can be found using an online source or phone app, an atlas or a topographic map. A site such as Veloroutes allows users to enter their address or city and find the elevation of their home.

A GPS phone app is also a source of information and might automatically display an address’s elevation. An atlas supplies statistics for various cities. Finding a location or one nearby should let a user find the elevation. A topographic map can be used to find the nearest marked line, and the number of lines can be counted to a particular location. Multiplying the number of lines by the contour interval and then adding the result to the nearest labeled line results in the elevation.
