Simplex

Features
Read full description

Simplex™ is a generic tool to support participative observation networks. The Simplex™ smart app is one component of a more complete observation system that, in addition to the app, comprises a webGIS interface and a database. The application allows you to do any kind of thematic observation by driving the observers step by step, through explicit icons, to the right observation item, and to finally declare it (with our without photo) with geographical and spatial stamp. Observers have access at any time and any location to environmental data for the last three days that are extracted on-demand from environmental databases. At each observation are attached selected environmental parameters that allows, at any time, to correlate some observations with environmental context. Simplex™ can host several observation networks, either of public type (i.e. open to anyone) or of private type. You can contract a license for a private one to create your own network. The license covers the configuration of the observation campaign (i.e. the selection and the hierarchy of icons and the required environmental parameters, if of interest to you). It also covers an access to a private webGIS that provides a synoptic view of the observation done by your network. Your data is kept safely on a private storage without any access by a third-party. Once created you can invite anyone you want to become an observer to your network. You can also easily change and adapt the icons at all time. The app allows on-line discussion (text) between network organizer and observers. Simplex™ app is available in several languages (Arabic, English, French, German, Italian, Norwegian and Spanish).
