地理信息系统(GIS)已经成为空间技术的核心，它集成了遥感(RS)和全球定位系统(GPS)等不同来源的广泛数据集。对十年(1998-2007年)期间出版的文献进行了汇编，并根据该技术在疟疾流行病学中的使用情况将其分为六类。对空间数据源、制图和地理处理工具、距离计算、数字高程模型(DEM)、缓冲区和地质统计分析等不同的地理信息系统模块进行了详细的研究，并根据导出的结果给出了实例。这些地理信息系统工具为了解疟疾的流行过程作出了巨大贡献，所引出的例子表明，地理信息系统现在被广泛用于疟疾控制的研究和决策。统计数据分析是目前分析空间数据集最一致和最成熟的一套工具。地理信息系统的预期未来发展与地质统计工具的利用相一致，这种工具与高质量的数据相结合，能够为疟疾流行病学及其在流行地区传播潜力的复杂性提供新的见解。
Geographical information System (GIS) has emerged as the core of the spatial technology which integrates wide range of dataset available from different sources including Remote Sensing (RS) and Global Positioning System (GPS). Literature published during the decade (1998-2007) has been compiled and grouped into six categories according to the usage of the technology in malaria epidemiology. Different GIS modules like spatial data sources, mapping and geo-processing tools, distance calculation, digital elevation model (DEM), buffer zone and geo-statistical analysis have been investigated in detail, illustrated with examples as per the derived results. These GIS tools have contributed immensely in understanding the epidemiological processes of malaria and examples drawn have shown that GIS is now widely used for research and decision making in malaria control. Statistical data analysis currently is the most consistent and established set of tools to analyze spatial datasets. The desired future development of GIS is in line with the utilization of geo-statistical tools which combined with high quality data has capability to provide new insight into malaria epidemiology and the complexity of its transmission potential in endemic areas.
