Descriptions
It comprises of three main components:
- DataStore
Data from any system is transferred into the GeoAxiom Vista DataStore which is MySQL database and includes a wizard (db.robot.c) for building SQL queries to retrieve data which can be viewed in a table or graph and saved to any computer. All operations are automatic and invisible to the user so there is no need to be a database specialist
- DataViewer
All data within the DataStore can be accessed via the DataViewer using a powerful web browser (db.data.browser) which allows the user to view trend lines, inclinometer data, real time displays and G-Maps
- Internet Publisher
Using a special web browser (db.web.browser) most of the information within db.data.browser can be published to the internet and can therefore be accessed via any internet browser.
Case Studies
Hillerød Track Monitoring
As part of a trial for Banedanmark, a Geosense MEMS track monitoring system was installed over an initial 20 metre length track at Hillerød near Copenhagen in Denmark to monitor the twist and cant of the track in an area of high instability. Following the initial trial, it was intended to install several systems in areas where instability is of major concern.
MEMS technology was chosen as it is not affected by temperature or vibration and the installation was undertaken during the night in temperatures of minus 15 Celsius.

The Chase Line Electrification
The Chase Line (Walsall to Rugeley) Electrification Project in the West Midlands covers a stretch of 10 miles of track with the route snaking through both urban and rural areas, including the densely wooded Cannock Chase, both in cuttings and embankments.
The project involved the erection of masts to carry the overhead line through some areas of historic shallow mining where differential settlements could cause issues with the masts.
For most of the route very few locations offered significant linear direct lines of site for wireless radio communication from Nodes to central Gateways. After signal coverage testing along the route, the WI-SOS 480 long-range remote wireless tilt meter monitoring was considered the safest, most sensitive and the most cost-effective solution.

River Humber Gas Pipeline Replacement Project
Work has been carried out on a £100m project to create a tunnel under the River Humber to carry one fifth of the UK’s gas supply to millions of homes.
The three-mile tunnel houses a new gas pipeline running between Goxhill in North Lincolnshire and Paull in East Yorkshire and was expected to take a year to build. National Grid needed to replace the current pipeline, which is in a trench just below the river bed and is at risk of being exposed by the tides.
The crown of the TBM passed 7m underneath an existing in-service gas pipe, approximately 10” in diameter and a few hundred meters from the reception shaft on the Paull side. On this existing gas pipe in-service, three spots were monitored for changes in strain as the pipe falls in the zone of influence of the TBM.
