遥感技术在第二次集体土地调查底图制作中的应用研究

Application Research of Remote Sensing Technology in Map Making for the Second Land Survey

第二次集体土地调查的主要技术手段是利用调查底图进行影像调绘。遥感数据源的选择则是底图制作工作的必要条件。本文以人眼的可视能力和混合像元的可识别能力为依据,在此基础上分析了当今常用的遥感数据源,确定了不同成图的要求适用遥感数据。本文分析了采用不同的图像增强方法处理异源遥感数据,阐述了标准分幅DOM制作及坐标系统的转换及算法。

The main technical means of second collective land survey is the image annotation using survey map .Remote sensing data source selection is a necessary condition for the base map production work .Based on the identification ability of human visual capacity and mixed pixels as the basis , based on the analysis of the commonly used remote sensing data source , applicable requirements of the different remote sensing data graph are determined .This paper analyzes different methods of image enhancement processing of remote sensing data, the transfer standard framing DOM production and coordinate system and algorithm .
