A Web-Geographical Information System for Real Time Monitoring of Arachthos River, Greece

摘要

The scope of this work is to present a Web-GIS that will monitor the broader area of Arachthos River in order to serve as an online mechanism for early warning and mapping of flood events. It describes briefly the main technologies for developing a web-based GIS system i.e. mapping technologies, developing databases and web applications. The advent of client-side web mapping has provided all the necessary tools to develop platforms for creating Web based Geographical Information Systems (Web-GIS). The information system combines data deriving from different sources such meteorological, geographical and water level data that are visualizing within the Web-GIS platform. The design and operation of the system aims to enhance the local government and relative stakeholders’ knowledge in order to improve decision making processes and efficient crisis management, in case of a flood event; while, another scope is also to keep the general public informed for the case of emergency situation.
