摘要
利用ERDAS Imagine 8.5对航片及地形图进行几何校正;经过影像粗解译和野外实地调查,对研究区土地利用现状进行分类并建立起解译标志;以ARCINFO GIS 9.0为平台,采用其中的ARCEDIT模块作为解译的基层模块,通过目视解译的方法对影像进行特征提取,结合Arcview3.3进行数据分析及图形整饰,达到图形分类、数据和图形输出的目的。由于航片分辨率高、控制点选取合理以及解译工序的合理安排,解译精度较高。
A method of geometry correction of aerial photo and topographic map by ERDAS Imagine 8. 5 is discussed. After cursory image interpretation and field investigation, the actual situation of land utilization in the investigated region was classified and its interpretation signs were established. Taking Arc/ Info GIS 9＋ 0 as platform and adopting its ARCEDIT module as the basic interpretation module, the feature information of images was extracted by visual interpretation. The data analysis and graph grooming were made by ArcView 3.3, so the goals of map classification, data and map output were achieved. For the high resolution of aerial photo, reasonable selection of control points as well as reasonable arrangement of interpreting procedures, the precision of image interpretation is high.
