Objectives of the Product

An important task of facility management is regular motion monitoring – checking whether the structure or its parts are moving. In the case of strategic infrastructures – such as roads, railways, bridges or industrial facilities – the motion monitoring is required by law and industry standards.
Currently, these monitoring activities are carried out exclusively using field surveying, which requires personal presence, therefore significant human resources and cost. It is carried out with low temporal frequency – a few times a year – and, as a result, gives relatively few measured points and point density.
By using the project’s solution, the field surveying method could be partially replaced by radar based (InSAR) motion analysis. The application allows the land surveying and InSAR processing data to be managed, analysed and represented together with user-friendly functions.

• The ability to import and transform the land survey data from most popular formats.
• The hybrid data analysis using InSAR and land survey data together, time gap management and prediction functionalities.
• The management functions for the processing area and the facility data.
• The possibility of integration to other system, in particular to Building Information Modelling (BIM)-based facility management systems.
• Advanced modules for customisable alert system and notification services.

Customers and their Needs

The targeted customer segment of the portal application are the road and railway network operators and maintainers, industrial plant maintainers and land surveying experts, who already perform motion detection of facilities or infrastructures by using field surveying data. Their main task is to prevent the facility’s damages, and their main points are the following:

• Personal presence is required.
• High-resource demand (human, car, surveying equipment)
• Relatively few measured points and point density.
• Measuring certain sites is difficult due to physical, operational or legal reasons.

The use of the web portal and its services provides the following advances to customers:

• Significantly higher measurement frequency and point density.
• Data visualisation and analysis functions.
• Less on-site presence and costs.
• Motion monitoring results can be shared easily among the surveyor, maintainer and authorities.

The added value lies in the possibility for the user to upload his previous land surveying measurement results in the form of CAD file exchange formats. These data and the results of the SAR based motion analysis are displayed and evaluated together. The end result is a hybrid application in which the results of two very different motion analysis methodologies can be interpreted together.e requirement definition phase, as they can provide information on the environmental and mechanical constraints for a typical EO mission. This information is used to derive board thermo-mechanical constraints, definition of physical interfaces, size and expected power consumption of the module.

Product description

The main components of the product that provide the services of the application are:

• Ground motion detection portal (at top of the figure below)
• Registration, login/logout and user management services
• Upload service for land survey data
• Order service for InSAR data processing
• Advanced data analysis services
• Business logic management services
• BIM integration services

The application provides clear and simple user interfaces. The appropriate front-end technology, the integrated map application and the client-side and third-party-based functions (editing data, viewing graphs) together ensure reliable use.
The application and the service components are scalable, the asynchronous functions provide predictable response times. The system ensures multitenant operation.

Added Value

The main focus of the solution is handling and analysing the two very different data sources (InSAR Line of sight, East/West, Vertical measurement versus the land surveying’s classical coordinate system and standards), with a market-oriented approach. Also, if the profession and industry accept, those InSAR results can be successfully used for motion analysis and infrastructure monitoring. Although competitors operate several web portals for displaying InSAR data and advanced data analysis in various fields, the joint use of data sets, data loading, visualisation, joint analysis and weighting, as well as services integrated with BIM systems, can be evaluated as unique. Weighting of the InSAR and land survey data also can be key to penetrate the market, by using different spatial methods like IDW, GWR, trend surface analysis.

Current Status

The kick-off meeting of the project was held on 21 August 2024. The activity is in the onboarding phase, the tasks related to the completion of the first milestone (RR) have begun.
The following technical work is being implemented:

• Consultations with partners and potential customers.
• Preliminary examination of the sample areas from the point of view of the quality of InSAR results available for the areas.
• Negotiation with the supplier regarding to geodetic data available for sample areas
