The Data Water Valorization Platform

In the context of climate change, water is a critical resource that must be managed very carefully. The ecosystem of water management is full of actors, each having a different responsibility and their own datasets which may be of value for other stakeholders. Currently, these datasets are not or are poorly shared. To tackle this issue, EGM has developed a Water Data Valorization Platform, that will enrich the SEDIMARK Marketplace ecosystem. It will be deployed in the municipality of Les Orres, where there is a need for an optimal way of handling all the data related to water, especially the one related to the Lac de Serre-Ponçon.

The platform revolves around the Stellio Context Information Broker, which allows connection and information sharing between all types of data and use cases. It is based on the European FIWARE open-source ecosystem which uses the NGSI-LD specification produced by ETSI. The platform provides some powerful visualization and business intelligence to view real time data or perform data analysis on a history of data and includes a set of modules specifically designed to deal with the need of actors in the water domain. Each module and its purpose are presented Hereafter.

Data collection module: In many cases, data is collected fully automatically, the workflow is set up once and then nothing else is to be done by the user. However, in some cases, the dataflow can only be automated up to a certain point, but still needs some input from a user.  For instance, a dataflow a could be automated but only a need the user to give an input file path or a list of attributes to select. This module allows the user to perform the required actions from a user-friendly interface directly in the platform without having to interact without the backend interface.

Data validation module: In the field of water data collection, the validation of the measurement is a very important part of the process. Indeed, most sensory devices are on the outside, subject to many potential disturbances, which need to be addressed. The data can be automatically pre-validated, but most actors in the water domain will want to perform a manual final validation of the data to ensure an optimal data quality. This module provides a user-friendly interface to perform this manual validation as easily and quickly as possible. It includes some optimized table and graph display of the attributes to be validated and allows to perform multiple actions (select multiple lines/columns, filter, perform basic mathematical operations, …) on the data to validate or invalidate them.

Calculation tool module: This module allows the user to launch all kinds of models available in the platform, such as Machine Learning and AI models, hydrological models, any kind of algorithm that takes one or many inputs to calculate one or many outputs.

Data Export module: After retrieving and processing its data on the platform, the user might want to export the data in different formats. This module allows the user to export its data in csv format. Optionally, the user can perform some temporal and/or geographical aggregation before exporting the data. In addition, the module proposes a possibility to export the data into a report or summary sheet, which works based on pre-registered report template. The user selects the template and the data to export to automatically generate an excel or word file.

Risk and Event management module: A common need in the water sector is to be able to set some threshold breach detection to monitor the behavior of the data. This module allows to create some Event to detect and historize the occurrence of threshold breach and missing data. In addition, it includes a risk management system, allowing the user to create a risk, i.e., defining some condition for different severity based on multiple measured attributes to monitor the risk and potentially be alerted whenever it occurs.

Alert creation module: Based on the risk and the event defined in the previous module, the user can define alerts that will trigger whenever the risk or event occurs. This module allows the user to set the condition on which the alert should trigger (e.g., risk ‘A’ occurred with severity ‘high’, or event ‘B’ occurred, …), the message to be delivered by the alert and the mailing list that should receive it.

Since the platform was designed to answer specifically to the need of the actors of the water domain, it includes a very narrow right and authorization management system, allowing to give to each specific actor (developer, data validator, data scientist, politic decider, citizen, …) the specific rights to access only the modules and/or dataset visualizations that are relevant to them. The water Data Valorization Platform will be deployed as a part of the SEDIMARK Marketplace. It will enrich the ecosystem with its modules, its services, and its dataset, to be used by many actors of the water domain but also any user with some data to be processed.
