Grand Lyon

TMA of the GIS platform and mapping business applications

The overall objective of this project was to make sure the upgrades to the Lyon metropolitan authority’s operational applications and the application itself functioned correctly in the GIS field.

Lyon metropolitan area (DINSI)’s IT department is responsible for providing assistance to the project owner and project management of the IT system.

As part of the maintenance of its 50 GIS applications, a third-party application maintenance service (TMA) was given over to Coexya in 2005 and renewed in 2009, 2013 and then 2017 for a new  four year period.
