The NexSIS project : Open Source softwares for civil protection geo-intelligence
2021-10-01, 14:00–14:30, Humahuaca

In the event of a major crisis like the terrorist attack in Paris at the Bataclan venue on November 13, 2015, the civil protection agents and organisations were dealing with a Massive flow of geolocated information (thousands of calls in a few minutes to the emergency centers) and a need for rapid decision-making based on territorialized information: location of attacks, position and availability of help, travel time, traffic, access, etc.

The NexSIS project aims to create a digital rescue platform providing all civil protection actors in France with a complete set of cloud operational services.

Open Source GIS solutions were chosen for this national project with strong technical requirements.

The technical prerequisites for an information system in SAAS mode intended for emergency services are high. It goes without saying that special attention must be paid to performance and safety. It is also necessary to build a modern and modular architecture capable of serving the needs of 250,000 potential users on the French territory.

The solution cannot be a black box. The modularity, interoperability, scalability and adaptability of open source solutions make it a first-class choice for building this large-scale solution.

Beyond technology, another key success factors for the Nexsis project are partnership and skills. NexSIS is build with an agile in-house team working in scrum mode. Product Owners are firemen working closely together with GIS experts and core Open Source developers.

We will show how solutions like Postgresql / PostGIS, Geoserver, OpenLayers and others are capable of meeting the challenges of an operational rescue system intended to save lives every day.
