地理信息系统 ( Geographical Inform ation System ,GIS)是以地理空间数据库为基础 ,在计算机软、硬件的支持下 ,对空间相关数据进行采集、管理、操作、分析、模拟和显示 ,并采用地理模型分析方法 ,适时提供多种空间和动态的地理信息 ,为地理研究和地理决策服务而建立起来的计算机技术系统。到目前为止 ,地理信息系统已被成功应用在莱姆病、疟疾和丝虫病等媒介传播疾病的控制工作中 ,为探索病因、预测疾病高危区域以及制订预防措施提供科学依据 ,为媒介传播疾病的研究提供了一个新工具
Geographical Information System (GIS) is based on geospatial database, with the support of computer software and hardware, it collects, manages, operates, analyzes, simulates and displays the spatial related data, and uses the geographic model analysis Method, timely provision of a variety of spatial and dynamic geographic information, computer science and technology systems established for geographic research and geographic decision-making services. To date, GIS has been successfully used in the control of vector-borne diseases such as Lyme disease, malaria and filariasis, providing a scientific basis for exploring causes, predicting high-risk areas of disease and developing preventive measures for the transmission of diseases Research provides a new tool
