摘要
在矢量地理信息数据的处理过程中,经常会遇到三个问题:一是部分数据通过人工无法进行处理;二是地理信息数据量庞大,人工处理工作量大;三是人工处理的数据精确度不高。通过程序自动对矢量地理信息数据进行处理,将很好地解决以上三个问题。用程序自动处理矢量地理信息数据的关键在于对矢量数据结构或形式的识别,也就是对矢量数据模式的识别。本文具体阐述了什么是矢量模式识别及其在地理信息数据处理中的应用。
In processing vector geographic information data, we often encounter three problems： one is that some data can not be pro- cessed artificially; the second is the huge quantity of geographic information data and artificial processing workload; and the third is that the accuracy of manual processing data is not high. Automatic processing of vector geographic information will be a very good solu- tion to solving these three problems. The key to automatic processing of vector geographic information data is to recognize the structure or form of vector data, in other words, the vector data pattern recognition. This article specifically elaborates what is vector pattern recognition and its application of geographic information data processing.
