基于QuickBird影像的校园地理信息系统设计

Campus geographic information system based on QuickBird image

校园作为城市或地区的一个缩影,范围小,信息量大,在利用大比例尺地形图研究时存在数据获取慢、较难更新的缺点。利用高分辨率遥感影像提取校园信息,能够真实、准确反映校园不同的地物之间的位置关系,为校园地理信息系统提供数据源,是其他格式无法比拟的。本文在Visual C++开发平台下,利用QuickBird影像获取的校园信息,通过MapX地图控件,实现快速、准确构建校园地理信息系统,为城市范围研究起到借鉴作用。

Campus,as a miniature of city or area,has characteristics with small scale and large amount of information the main drawbacks are slow data acquisition and hard data update with the large-scale topographic maps.It is difficult to grasp the spatial location information of campus.Using high resolution remote sensing image for campus information extraction,could reflect the different relationship between campus features,and provided the data source for the campus geographic information system,which was unmatched by other formats.Based on Visual C++ development platform,with obtained campus information from QuickBird image,using the MapX control,the fast accurate system was established,the study could play a reference role in the city-wide research.
