摘要： In an embodiment, a computer-implemented method of selecting sampling locations in a field is disclosed. The method comprises receiving, by a processor, input data including a map for a management zone in a field indicating one or more values of a set of agricultural characteristics for each of a plurality of locations in the management zone. The method further comprises identifying, by the processor, a set of values for the set of agricultural characteristics for each of a group of locations in the management zone based on map. In addition, the method comprises normalizing a set of model values for the set of agricultural characteristics used by an agricultural modeling tool and the set of values of the set of agricultural characteristics for each of the group of locations in the management zone. The method also comprises selecting one of the group of locations as a sampling location based on the normalized set of model values, the normalized sets of values for the group of locations, and a first distance constraint related to a distance to a boundary of the management zone. Finally, the method comprises causing display of information regarding the selected location.

摘要： A system for tracking a below-ground transmitter from an aerial receiver. The receiver has an antenna assembly, a processor, and a propulsion system. The antenna assembly detects the magnetic field from an underground transmitter and generates an antenna signal. The processor is programmed to receive the antenna signal and generate a command signal, which moves the receiver to a position above the transmitter. Once in the desired position, which may be a reference plane at a fixed elevation, the antenna assembly measures the magnetic field to determine the location of the drill bit along borepath.

摘要： Technology for performing magnetic field gradient measurements is described. The magnetic field gradient measurements for specific positions on the Earth can be performed from a moving platform. The magnetic field gradient measurements can be identified as being affected by a level of error that exceeds a defined threshold. A correction value can be generated to compensate for the error in the magnetic field gradient measurements. The correction value can be applied to the magnetic field gradient measurements in order to obtain magnetic field gradient measurements with a reduced level of error.
