摘要
样地是中药资源普查系统随机生成的特定区域,样地常地处偏僻地区,使用普通定位系统难以准确、高效地抵达样地点,且在到达样地前无法获取样地周边道路和环境状况信息,给野外调查工作增加了难度。在全国第四次中药资源普查中,我们将样地GPS信息转换为Google Earth地标文件,并导入手机端Google Earth应用中,实现搜寻样地的实时定位功能,直观地显示了卫星地图上的样地信息,为中药资源普查提供更为便捷、高效、直观的样地定位方式。
The areas for resource survey are often the specific areas randomly-generated from the resource information system. These areas are always located in the remote places and make the field survey work time-consuming and inaccuracy by using the common position system. In addition, the road and the environment around the survey sites are always unavailable until the investigator get there. In this paper we transformed the GPS information of survey area into the landmark file and imported it into the Google Earth application in the cellphone. As a result, the survey areas can be accurately and real-time searched in the cellphone. In addition, the road and the environment around the survey sites can be shown on the cellphone screen. Therefore, we provide a convenience, efficient and visual position system for the field investigation of resource survey.
