摘要
采用地理信息系统的空间查询技术,解决了遥感卫星数据编目系统对多元化地理信息的需求问题。描述了空间查询技术和编目系统,同时分析了二者相结合的优点。提出了将编目处理中生成的标准景图像视为几何点对象,经过投影转换在地理信息系统数据集中进行空间查询,获取丰富的地理信息以扩充编目元信息的方法。实现的多元地理信息的编目系统丰富了遥感数据的描述信息,使得用户能够更直观、更方便、更有效地查询遥感数据,从而达到高效、便捷地利用遥感图像的目的。
With spatial query technology of GIS, the requirement of polynary geographic information in remote sensing data catalogue system has been resolved. Through illustrating the spatial query technology and the catalogue system,and analyzing the excellence of the integration,this paper regarded the image created by catalogue system as a geometric point,then implemented spatial query with the projective point in dataset of GIS. FinalLy,the catalogue system was expanded by the abundant geographic information. With the descriptive information of remote sensing data in new catalogue system,users can query the remote sensing data more directly,more covenintly and more deffectively. The results suggest that the remote sensing image＇s efficiency has been developed.
