1. An apparatus, comprising:

  • a platform configured to traverse on the ground and along a path;

    a position sensor physically coupled to the platform and configured to provide position data as the platform traverses along the path;

    a sensor arrangement physically coupled to the platform and configured to provide subsurface sensor data as the platform traverses along the path, the sensor arrangement comprising a plurality of sensors spaced apart from one another and at a known offset position relative to the position sensor; and

    a processor comprising an output and configured to;

    produce geometrically correct position data by correcting for curvilinear dynamic motion errors in the position data using positional offset data defining the known offset position of each sensor relative to the position sensor;

    associate a geometrically correct position with the data provided by each of the sensors; and

    provide output data comprising the sensor data and associated geometrically correct position data for each of the sensors at the output of the processor.
