【摘要】 目的综合评价GPS与Google Earth建立血防工作信息空间数据库的实用性。方法选择大观区为研究对象,使用GPSMAP76型手持机,对该区流行村、钉螺环境、阳性钉螺及急感发生地的经纬度进行测定,并通过一些配套软件,将其导入到Google Earth地图上,在地图上建立血防工作空间数据库。结果导入到Google Earth的数据可以按照分类分别显示、制图,做一些简单的空间分析和预警,精准测量长度和计算钉螺面积。结论应用GPS与Google Earth建立血防工作空间数据库简单易行,有一定的实际应用价值。更多还原

【Abstract】 Objective To evaluate spatial database for schistosomiasis established by using GPS and Google Earth.Methods Daguan District in Anqing City was selected as the research object,the GPSMAP76handset was used to determine the latitude and longitude data of endemic villages,snail environments,positive snail areas and acute infection areas of the district,then the data were transferred into the Google Earth map to establish spatial database for schistosomiasis.Results The transferred data on Google Earth can be displayed by category,and in the meantime,the data can be used for drawing,doing some simple spatial analysis and early warning,measuring the length and calculating the snail-infected areas.Conclusion It is very easy to establish spatial database for schistosomiasis by using GPS and Google Earth,which has the value of practical application.更多还原
