研究目的:大规模、宽范围的采用遥感卫星影像进行土地更新调查工作,在我省尚属首次,研究和分析这一新的方法能否满足我省1:10000调查比例尺的精度要求,从而掌握遥感卫星影像的特点及规律,保证土地更新调查的成果质量。研究方法:重点是地类可解度和几何精度两方面,一定层次的定性与定量分析方法。研究结果:采用Spot-5高分辨率遥感数据进行1:10000土地更新调查是一种经济、有效、可行的方法,同时提出了保证质量的措施。
Research purposes: For large-scale and wide-scale land renewal surveys using remote sensing satellite images, it is the first time in our province to study and analyze whether this new method can meet the accuracy requirement of 1: 10000 survey scale in our province to master The characteristics and laws of remote sensing satellite images ensure the quality of the results of the land renewal survey. Research methods: The emphasis is on the methods of qualitative and quantitative analysis of the degree of solvability and geometric accuracy of the ground class. Findings: The 1: 10000 land-use survey using Spot-5 high-resolution remote sensing data is an economical, effective and feasible method. At the same time, some measures are put forward to ensure quality.
