The New Strategy of Geographic Information Emergency Service Based on PDF Structure
Influenced by many factors such as the prolonged production period, the disunity of trans-media visual output results and the imprecision of thinking in security problem under condition of the traditional emergency surveying and mapping service, GIS (Geographic Information System) productions are often very hard to provide information service which is necessary but not leading to security problem at the first time by the needful model for the specific users. After some problems exposed in current emergency surveying and mapping service of rescue are deeply analyzed, the article presents a new strategy of geographic information emergency service based on PDF (Portable Document Format) structure to adapt to actual needs in all kinds of sudden-onset disasters. The strategy not only ensures data quality and shortens the work period but also plays active roles in application range, transmission speed and security control.
