Since QGIS-Server has been released, we have built an application to facilitate the publication of maps created with QGIS on the Web. LizMap is OpenSource and based on OpenSource softwares : QGIS and QGIS server for web services and rendering, OpenLayers for building web maps, Jelix a PHP framework, jQuery and Bootstrap for the user interface. The presentation will explain why we chose QGIS-Server and will describe the full publication process. Key features will be presented, as dynamic map respecting QGIS project configuration, html5 responsive interface (mobile friendly), rights management, automatic caching, printing, ediion tool, etc. A quick demonstration will show Lizmap in action.
