基于ArcGIS的一种正射影像数据管理入库方法

A method on database management of orthoimages based on ArcGIS

正射影像数据作为空间数据的一种载体,在地理信息领域中的地位变得越来越重要。随着应用的深入和计算机软、硬件的发展,影像数据管理方式已由传统的文件方式向数据库方式转变。本文针对正射影像数据管理入库,提出了基于ArcGIS的影像数据建库方法。对正射影像数据管理入库涉及的影像数据存储方式、影像数据压缩、正射影像数据集的属性结构、影像数据的时态管理以及客户端软件的开发等问题进行了分析与研究。方法实用、可靠,在杭州市1:2000比例尺正射影像数据入库中得到了应用。

Orthoimage data,as a kind of carrier of spatial data,acts as a more and more important role in geography information field.With in-depth applications and computer software and hardware developments,the management method of image data has changed from the traditional file mode to the database mode.In this paper,for the management and storage of orthoimage data,the method for building database has been put forward.The store way of orthoimage data based on ArcSDE,compression method,attribute structure,management of temporal changes have been studied and analyzed.The development of client software,for orthoimage data management and database,has been introduced.The method has been applied to build database of orthoimage data of 1 ∶ 2000 scale in Hangzhou and achieved good results,which has been proved to be practical,reasonable and reliable.
