基于omap手机客户端进行地球化学样品采集的方法探讨

以往进行地球化学样品采集时,通常用的方法有2种:一是使用GPS手持机结合地形图的方法进行野外定点取样;二是利用"掌上机"移动终端进行野外定点采集。在此,介绍一种使用智能手机进行样品采集的方法——借助omap手机客户端下载Google Earth影像地图作为工作底图,利用GPS参数进行偏差校正后,将设计点位和方里网导入该软件内,即可同车载导航仪一样,进行导航定点采样。该方法简单有效,不再依赖地形图,提高了野外找点效率,定点误差小于3 m,便于推广应用。

Study on the Method of Collecting Geochemical Samples Based on omap Mobile Client

In the past, two methods are generally used to collect geochemical samples, one is GPS handhelds, combining with topographic maps for field sampling; the other is "handheld" mobile terminal for field fixed-point collection. In this paper, a method which will realize sample collection by using the smart phone has been introduced. It will download Google Earth image map as a working base map with the help of omap mobile client. After using GPS parameters for deviation correction, the design points and Fangli network will be led into the software. Then the navigation point sampling will be carried out like car navigation system. This method is simple and effective. It does not need to rely on the topographic map. Thus, the efficiency for finding the points in the field will be improved, and the fixed point error will be less than 3m. It is also easy to widen the application scope.
