This International Standard defines a method to describe the geometry of a feature that moves as a rigid body.Such movement has the following characteristics.a) The feature moves within any domain composed of spatial objects as specified in ISO 19107.b) The feature may move along a planned route, but it may deviate from the planned route.c) Motion may be influenced by physical forces, such as orbital, gravitational, or inertial forces.d) Motion of a feature may influence or be influenced by other features, for example:1) The moving feature might follow a predefined route (e.g. road), perhaps part of a network, and might change routes at known points (e.g. b
