吉林省城区影像图方案设计与实现

Scheme Design and Realization of Urban Image Map in Jilin Province

正射影像图是一种带有地面遥感影像的地图,利用航空像片或卫星遥感影像制作。影像地图通过几何纠正、投影变换和比例尺变化,添加一些地图符号和注记制作。城区影像图是具有影像内容、线划要素、注记要素、符号要素、数学基础、图廓整饰的地图,可以运用地图制图的方法,使城市区域内的地理要素呈现在地图上,能够直观、有效、富有立体感地反映某一城区的地理空间信息。本文主要介绍吉林省城区影像图的方案设计与实现过程。

Orthophoto is a map containing ground information of remote sensing images made by aerial photographs or satellite remote sensing images.Image map is made by geometric rectification,projection transformation,scale change,adding map symbols and notes.Urban image map is a map with image content,line elements,annotation elements,symbol elements,mathematical basis and border decoration.The method of cartography can be used to make the geographical elements in the urban area present on the map,which can reflect the geospatial information of a certain city intuitively,effectively and fully 3D sense.This paper mainly introduces the scheme design and implementation process of urban image map in Jilin Province.
