Information System: Georeferenced Database

Abstract

The goal of the implemented system is to provide useful tools to monitor in real time the positions of the vehicles that share the Green Move system. Data can be accessed in two different ways: by the Green Move WebGIS, for browsers; by the geoweb service that delivers the data accordingly to the Web Map Service and Web Feature Service standards that are defined by Open Geospatial Consortium (OGC), for OGC Web Services clients. Static information, like vehicles identifiers or registrations numbers, is published. Moreover, real-time data are published and updated every 5 s: vehicles positions or other data from onboard Global Navigation Satellite System as well as useful data from others sensors, like speed and battery charge level and static information, like vehicle identifier, registration number. Furthermore, delivered vehicles positions are processed to correctly georeference them in correspondence of roads. Free and open-source software has been used to implement the service: MapServer, OpenLayers, and PostGIS/PostgreSQL provide the GeoDB, and OpenStreetMap service is used for road maps.
