Design and Development of Emergency Response Geographic Information Platform Based on Web Service

Emergency management/Emergency service is a compelling domain for applying GIS Web Service. GIS Web Service expands the further development of GIS. A Web service is described using XML-standards like the WSDL (Web Service Description Language). Web Services, are different from Web applications, don’t require people to use; but software applications to call. Thus, the Web service does not have any user interface, but the Web Service applications provide user interface. GIS Web Service can also support customizable spatial analysis functions. ArcGIS Server services can be used to develop two types of Web services: ArcGIS Server data web services and application function Web services. Via the local Web server Web Service framework, to achieve Web services of applications, but this type of Web service client is not ArcObjects application. ArcGIS Server ADF takes full advantage of Web services can be used to connect ArcGIS Server services. In the Web Service layer, using the popular WSDL (Web Service Definition Language), UDDI (Universal Description Discovery and Integration), SOAP (Simple Object Access Protocol), to descript, register and release the GIS service provided by the application service layer. For sharing geographic information resources in different places, ArcGIS Server provide some modes to find these resources, such as ArcGIS local services, ArcGIS Network Services, ArcIMS services, ArcWeb services, WMS services. Directory services generates in ArcGIS Server Manager, ArcGIS Server Manager take charge for the service requested of receiving, analysis, finding, positioning, and returned service description information to services requester. * Corresponding author.
