GIS与遥感技术制作影像地图的应用研究

摘要

This paper discusses city map making by GIS and remote sensing technology.First,pretreatment of the city’s remote sensing data is processed by professional software “ENVI”,the processed data is saved as TIFF format.A “ShapeFile” file is created in “ArcCatalog”,and loaded into ArcMap to depict the shape of the study area.The study area is cut out by using the cutting function of ArcMap.Information extracted from the study area is supplemented with map symbols to represent or describe the mapping object.%本文以GIS与遥感技术为平台，应用该平台制作某城区的影像地图。首先利用专业处理遥感数据的ENVI软件对某城区的遥感数据进行预处理；把处理好的数据保存为TIFF格式；利用ArcGIS软件，在ArcCatalog下新建一个shapefile的面文件，加载进ArcMap中描绘出研究区的形状；利用ArcMap中的裁剪功能裁剪出研究区；在研究区上提取出信息，辅以地图符号来表现或说明制图对象。
