通过在森林资源二类调查中应用PDA进行数据采集,大大提高了野外调查设计的精度和工作效率,内业整理也省去了许多中间环节,减少了人为误差,极大的节省了内业工作的时间,且实现了内业成图一体化和无纸化办公的作业流程。在二类调查工作中,PDA是与“3S”技术相结合应用的。 By using PDA for data collection in the second type of forest resources survey, the accuracy and efficiency of the field investigation and design are greatly improved. Many internal links are eliminated in the field work, which reduces man-made errors and greatly saves internal work Of the time, and to achieve the integration of internal mapping and paperless office work processes. In the second type of investigation, PDA is used in combination with “3S” technology.
