When a flooding disaster occurs, the control of ground traffic in and around the flooded area is a critical problem since the flood results in damages to roads and bridges. The static map may not always help people to make a right decision for evacuation. The optimal path which is calculated from the normal situation in a road network is not always the safest route since some roads are under water. Thus, it is necessary for people to obtain the dynamic information and instructions to evacuation.
In this project, a webGIS based application
for flood rescue is proposed. It is developed with Oracle spatial network data
model and Oracle application server 10g Mapviewer technologies. The former is
used to build a road network for
This project provides a methodology for creating a map, delivering spatial data, and viewing map in Oracle database by directly using Oracle Spatial technology that is different from traditional technologies. Users can render PL/SQL functions to manipulate Oracle spatial data, and also process spatial operators by SQL statements. Furthermore, Oracle Spatial provides a simple and effective way of storing and analyzing spatial data within the same database. Besides this contribution, this project offers a methodology to solve emergency problems by using Geographic Information System technology.
