Abstract: A method of mapping the going conditions for a racecourse comprises surveying the racecourse soil conductivity over the course using soil conductivity measuring means and mapping the conductivity data produced by the conductivity measuring means according to the locations at which the conductivity data were obtained, so as to produce a map of the racecourse showing variations in soil conductivity. The racecourse is then sectioned along its length so as to produce a series of zones, wherein the variations shown in the soil conductivity map are utilized in choosing the sizes of the zones, the going condition in each zone is determined and a map of the racecourse displaying the going conditions along the racecourse is produced.

Abstract: A method of monitoring a plurality of competitors in a sporting event, comprises having each of said plurality of competitors carry a respective position locating device, arranging for the position locating devices to make location determinations at intervals and provide such determinations as output positional location data for the respective competitors of said plurality of competitors and collecting output data for the plurality of competitors.

Abstract: An apparatus for analysing and mapping soil and/or terrain for physical and/or chemical properties thereof, comprises a sensor 1 for measuring conductivity of soil by electromagnetic induction, the device being movable over an area of ground to be analysed and mapped, a differential global positioning satellite (DGPS) receiver system 12 for determining the location of the sensor 1 on the area of the ground 30 to be analysed and mapped, and a personal computer (PC) 19 in communication with sensor 1 and DGPS system 12 for capturing the ground conductivity data from the sensor 1 in association with the determined location of the sensor 1 at which the conductivity data are obtained. The captured data can subsequently be used to generate soil maps of the area 30, showing variations in a range of soil parameters such as nutrients, pH, water content or soil type, from which improved ground management strategies can be developed.
