1. A method for adjusting geological data representing a model of the characteristics of a geological region, to better match data acquired from the geological region, the method being implemented in a programmed computer comprising a processor, a data storage system, at least one input device, and at least one output device, the method and the data being stored on computer-readable media, the method comprisingorganizing the data on the computer-readable media to represent a first geometry element, the first geometry element corresponding to a subset of the region and having an interior, boundary and exterior and having points each point having a location on the interior or the boundary of the first geometry element, and a second geometry element, the second geometry element having an interior, an external boundary and an exterior and having points each point having a location on the interior or the external boundary of the second geometry element;

  • aligning at least a portion of the points of the second geometry element with at least a portion of the points of the first geometry element in response to input data received by the programmed computer through at least one of the input devices;

    classifying the second geometry element against the first geometry element to combine the first and second geometry elements, wherein classifying comprises deciding whether to retain a point on one of the geometry elements depending on whether the location of the point coincides with the interior, boundary or exterior of the other geometry element;

    wherein not retaining a point comprisesdeactivating the point if the geometry element of which it is a part has been designated a feature;

    discarding the point otherwiseapplying the retained points to at least one of the output devices.
