Techniques for topography recording are provided. In at least some implementations, a topography recording device includes a position determination unit configured to obtain coordinate data of a location; a sensor unit configured to determine the inclination of terrain at the location; a processing unit coupled to the position determination unit and the sensor unit, and configured to calculate the gradient of the terrain at the location based on the inclination of the terrain at the location, and to generate a map indicating three-dimensional terrain in the vicinity of the location based on the coordinate data of the location and the gradient of the terrain at the location. |
