摘要
数字地球是近几年提出的一个重要概念。与此相对应的是数字城市的概念。课题组及时进入了数字城市的研究前沿。该文阐述了数字城市遥感信息三维景观生成系统的初步研究成果,内容主要包括将空中拍摄的遥感图象进行模式识别形成和存储矢量数据,读取数据绘制三维景观,动态显示三维景观等,取得了比较好的效果。
Digital earth is a important concept put forward recent years,digital city is a concept corresponding to it.The item comes duly into research field of digital city.The paper introduces the abecedarian research results in system of forming three-dimensional landscape of remote sensing information about digital city,its effect is obvious.It consists of mode distinguish to form vector data for remote sensing image filmed in firmament ,drawing three-dimensional landscape by inputing data,dynamic show of three-dimensional landscape.
