手持GPS在草原调查与制图中的应用

Application of handheld GPS to grassland resource investigation and mapping

全球定位系统(GPS)是当代发展非常迅速的信息技术系统,运用领域也由最初的高端军事领域深入到日常的生产生活中。运用GPS技术进行草原调查,是草原调查数字化、信息化的趋势。本研究介绍了Trimble JunoSB手持机在草原调查中各阶段的应用,系统地总结归纳了手持GPS在草原调查与制图中的应用技术和方法,为应用GPS技术开展草原资源调查与制图工作提供参考。

Global Positioning System （GPS） is a much rapid development information technology system, and its application areas have transferred into the daily production and life from the initial high-end military area. Application of GPS technology to grassland survey is the trend of digitization and informatization of grassland survey. This study introduced the application of the Trimble Juno SB handheld receiver in the process of grassland survey at the various stages, and summarized and generalized the technology and method in grassland investigation and mapping, which would provide the information for grassland resource investigation and mapping by GIS technology.
