摘要
油指纹库和溢油鉴别系统的构建对溢油鉴别具有重要意义,而数据库更新对保持数据库的现实性又有着重要的作用。本文首先阐述地理信息系统(GIS)数据库更新的含义,然后介绍数据库增量更新和完全更新两种机制。在对油指纹数字化鉴别系统的数据内容以及对数据更新具体需求分析的基础上,讨论系统B/S(Browse/Server)部分的数据更新机制,并详细论述更新机制的实现过程。
The construction of oil fingerprinting database and spilled oil identification system plays an important role in identifying leaked oil. At the same time updating of database is vital to the actuality of database. The definition of GIS database updating is explained firstly, then incremental-updating and complete-updating methods of GIS database updating are explained. Based on the data content and tile analysis of data updating requirement in the digital identification of oil fingerprint system, the data updating method of B/S database is discussed and the process of updating is explained specifically.
