(cartography) A value relating to distance east of a standard meridian but with a constant added to make the numbers convenient. For instance, in UTM the value 500,000 is added to the easting from the center of each zone to return a false easting that is never negative (the smallest true easting is approximately -340,000 which is set to false easting of 160,000).

日本語の意味
地図作成で用いられる用語。基準となる子午線からの実際の東方向の距離（実際のイースティング）に、計算を容易にするためにあらかじめ定数を加算した値。たとえばUTM座標系では、各ゾーンの中心からの東方向の距離に500,000が加えられており、これにより値が常に正となるように調整される。
