A method of prioritizing anomalies in a linear conductor buried under a ground surface includes the steps of obtaining prioritization values for a plurality of anomalies along a linear conductor, and ranking the prioritization values according to magnitude. For each anomaly, a prioritization value is obtained by: locating an anomaly; for each anomaly, determining a current, a depth of cover, and a voltage gradient using spaced voltage probes; using the depth of cover and the voltage gradient, calculating an effective probe spacing of the first and second voltage probes relative to the anomaly on the conductor; and determining the prioritization value of the anomaly based on a linear relationship between the voltage gradient and the product of the current and the effective probe spacing.

Method of prioritizing anomalies in a buried linear conductor

A multiplexer includes a body having a mechanism, incorporated into the body, for receiving more than one incoming data stream and converting the more than one data stream into a single output stream. An integral time clock is incorporated into the body and is adapted to incrementally time stamp each incoming data stream. The processor on the device also runs software to parse user selected data streams for the purpose of filtering out unnecessary data from the incoming streams, thereby reducing the volume of data and, in particular unwanted data, from being processed and/or logged from the device. The integration of a multimeter for voltage and amperage reading acquisition also reduces the need for external peripheral devices being attached to the device.

Survey controller multiplexer

A method of data acquisition during survey of buried linear conductors. A first step involves passing a dynamic data stream of data from survey instruments through a filtering software adapted to reduce the volume of data being processed. A second step involves setting a survey interval within the software, the survey interval being a selected distance between survey points in order to provide a desired survey point density. A third step involves setting a geographic activation buffer within the software in relation to the survey interval. The filtering software is programmed to process data within the activation buffer separately from the dynamic data stream.
