Development of a Method based on MobileGIS and VGI to Improve Relief for Victims in Times of Crisis

Due to the value of time in disaster relief, access to current information about the geographical location and physical condition of the injured and the use of new technologies and methods of GIS is important. The purpose of this study is to create a platform that uses MobileGIS, WebGIS and VGI technology to transfer and collect immediate and accurate information that leads to reducing relief time, increasing the speed of sending online or offline assistance requests by victims and reducing casualties. Real-time information on the physical condition and position of the injured person according to the required hardware facilities and the importance of time in responding to the needs of the injured is provided by each victim and used in this system .In this research, the information sent by the victims and those around them has been used. The information sent in the geoserver is analyzed .At the disaster, due to solving the problem of disconnecting the Internet, the output of this research was used as a mobile application with Android and IOS operating systems. In addition, the web version of the system was available when connected to the Internet. After the implementation of this system, with the obtained information, an Instant map was made available to the rescue manager, which included mapping the type of assistance and relief for each person or in groups for a group of injured in a specific geographical area, which help to assistance-and-relief managerschr('39') decision-making process.
