Summary PRIME (PRoactive Infrastructure Monitoring & Evaluation) is a low-cost geoelectrical ground monitoring system developed by the British Geological Survey. It is designed to integrate with standardised technologies and information delivery platforms to provide remote, near real-time, volumetric monitoring of infrastructure earthworks condition, thereby aiding asset failure prediction and timely intervention. A key recent development has been the implementation of a fully automated data processing workflow to enable regular and timely delivery of information to end-users. It is a customisable procedure, which enables each monitoring objective to have its own combination of processing steps applied to its data. The standard workflow consists of: data filtering and quality assurance; motion sensing (under development); inverse image generation; property translation via petrophysical relationships; and image analysis. The flexible implementation of the workflow will allow for new processing steps to be incorporated as they are developed.
