智能手机结合谷歌地球在血防查螺中的应用

Concurrent application of smartphone with Google Earth to survey of Oncomelania hupensis

目的研究智能手机结合谷歌地球在血防查螺中的应用。方法首先给智能手机加载"多点GPS"软件。在现场查螺中,通过手机端采集调查框的GPS数据及现场照片。手机内数据以KML/KMZ格式导出到电脑,借助相关软件,很容易的实现KML与Excel格式的相互转化。原始查螺数据经整理后,导入到谷歌地球以展示原始螺情。结果获取了查螺框点的GPS信息及现场照片,建立了查螺空间数据库,并利用谷歌地球直观的展示了原始螺情。结论利用智能手机加载"多点GPS"软件,取代传统的手持式GPS定位仪,在现场查螺工作中有较好的体验。智能手机结合谷歌地球用于建立查螺工作空间数据库简单易行,实现了查螺数据的数字化、图像化管理,有一定的实际应用价值。

Objective To assess the application value of concurrent smartphone with Google Earth to survey of Oncomelania hupensis. Methods HEAD GPS software was initially loaded in the smart mobile phone. The GPS data and photos of the field survey on the status of snail were collected with the smartphone, and were exported from the mobile phone to the computer in format of KML/KMZ that was converted into Ex-cel file format using a specific software. Then, the data were imported into Google Earth after processing, which was originally displayed in the Google map. Results The information of the snail survey point was ob-tained, and the geospatial database for snail status and distribution was successful established. This made it possi-ble to display the original snail condition in Google Earth. Conclusion Smartphone loaded with HEAD GPS software can replace traditionally hand-held GPS positioning device, which makes better experience in the field survey on the snail status. Importantly, this technique can be practical value in management of the data in digital manner and images obtained in filed survey of the snails due to its convenience.
