One method includes adjusting a scan geometry configuration of the remote sensing device during the measurement campaign based on measurement data acquired in a previous scan geometry configuration. In another method, the remote sensing device is configured in a scan geometry configuration having a plurality of scan geometries, and following acquisition of a measurement data set by the remote sensing device at a first time interval, one of the scan geometries indicative of an improved or optimal scan geometry at the first time interval is selected. The remote sensing device forms part of a remote sensing system and includes an optical source emitting a probe as a light beam along different lines of sight. The remote sensing device includes or is operatively associated with a receiver for detecting the reflected probe. ## Claims ### Claim 1 A method for use in remote sensing applications associated with a wind energy capture device in the form of a wind turbine or a tidal energy capture device in the form of a tidal turbine, the method comprising: receiving measurement data acquired previously during a remote sensing measurement campaign;
