Visualization of flood data using HTML5 technologies

Human civilization always used to settle near water sources, such as rivers, lakes and seas. But, beside the vast benefits that these regions offer, they sometimes present a huge threat of flooding the inhabited areas, when even the human life could be endangered. Thus, a systems that would offer an early information about the flood state of an endangered region is crucial for all the inhabitants, so they can base their quick actions on real and accurate data and not only on certain speculations. This paper presents a low cost solution that offers precise information about a flooded (or high risk) region using current web technologies. The system presents mapped data visualizations that show the position, the water level and the time of the last condition of multiple marked map points representing the flood sensors placement
