Research and application of heat map system for resource allocation of flood control based on GIS

Abstract

Flood control resources are valuable resources for flood control and rescue, providing the flood relief work with the most direct rescue workers, tools as well as equipment. With the continuous development of society and economy, local governments at all levels, especially those of which are seriously affected by flood and waterlogging, have raised higher requirements for the allocation of flood control resources. When disasters such as flood and waterlogging happen, a reasonable allocation of flood control resources can quickly deploy relevant flood control resources for the disaster relief work and play an important role in reducing damage to personnel and property loss to a minimum, which stabilizes and promotes the socioeconomic development. Research of resource allocation of flood control based on GIS (Geographic Information System) is gradually becoming an important technical support for scientific resource allocation. This research focuses on the introduction of the characteristics and advantages of the heat map system based on GIS and its application in resource allocation of flood control. The important role the heat map system based on GIS plays in allocation and management of flood control resources is introduced in the applying case of Guangzhou.
