WEB GIS in Natural Disasters Integrated Management

INTRODUCTION: There are over ۴۰ natural disasters and subgroups in the world that thirty one have occurred in Iran according to the studies and evaluations. For this, decreasing and preventing risks, it is necessary to have an integrated management of natural disasters since there are no safe places anywhere completely. GIS can be used in natural disasters integrated management dynamically. Organizing correct data is the first role of GIS in Disaster Management. Not only GIS commences with a sustainable structure for data with different nature, scale, format and subject but also follows by database protection, modernization, dissemination and development. In fact, GIS constructs and develops natural disasters integrated management. Recently WebGIS makes it possible to share the geographical information by designing Metadata and develop natural disasters integrated management. The map scale is ۱:۲۵۰۰۰۰ and data bank is in Arc GIS; Metadata is designed in the standard pattern of ISO and FDGC in web. Regarding to the results, it is necessary to have a special standard for designing the relief management Metadata. In one hand, it should be coordinated with national geographical databank and in the other hand it should be formed base on understanding disaster principles. Here it is presented a disaster geographical information standardization pattern for integrated management of natural disasters.
