摘要
土地利用外业调查工作是核实变化图斑范围、类型和面积的重要环节,在整个遥感监测工作中起着承上启下的作用,利用高分辨遥感数据进行年度或若干年度变化监测,每个县平均能检测的图斑数以千计,采用以往人机交互方式填写外业记录表,工作量大、易出错且极易造成图表内容的不一致。本文以国土资源部土地利用动态研究为基础,在对外业调查记录表各表项进行详细分析的基础上,探索了外业调查记录表自动填写技术,并编程实现了部分表项的计算机自动填写。
The purpose of this study is to find a convenient way to fill in the tables for field survey in land-use dynamic monitoring. Methods for documentation and systematic analysis were employed in this paper. A practical method of tabular auto-generation was suggested and put into practical use in the land-use dynamic monitoring project of 2003. The technology shows remarkable advantages and high efficiency.
