Description

Nessie platform is an information system, developed within NTUA, able to acquire, process and store, and in general to manage, high-resolution data from IoT agends, such as sensors and smart meters, coupled with analytics (to translate the data into information) and visualisation capabilities to present the information to the end-users.

Nessie platform is composed by 6 independent components: a) the data collector/parser components that collects raw data from a source, such as an FTP server; b) the Data Mapper component that formats the data in way that is supported by the third component, the Database server; c) The GIS-enabled PostgreSQL Database Server that stores the data; d) The Apache Web Server that supports the web character of Nessie; e) the Back-end engine, the heart of Nessie, that supports the processing of stored data and implements a series of embedded analytics; f) And finally, the web interface that delivers information to the end-user.

Target audience

Nessie primarily targets water utilities, industries, technology providers, end-users, householders to get access, analyse and visualise real-time data from IoT agents.

Actors, their roles and interactions

Nessie is a highly customisable system which can be adapted to support the specific requirements of any smart monitoring and control system. The system is continously being upgraded in the framework of EU- and National-funded projects, and so far it has been deployed to support smart applications for the real-time monitoring and control of water consumption (for both water utilities and end-users/householders), remote control of Sewer Mining Units and management of Subsurface Water Systems. Currently, special focus has been given to connect Nessie with FIWARE platform (in the framework of Fiware4Water project) to support the development of interoperable and standardised digital solutions.

Through Nessie, technology providers and water utilities give access to real-time data collected from smart meters. Householders and water utilities get access, analyse and visualise data through the dashboard.

Unique selling points

Nessie system is a in-house product, developed within NTUA.
