面向全国经济普查需求的专家系统地理编码方法

After analyzing those domestic and international geocoding methods, this paper proposed an expert system-based geocoding method for national economic census application. This method mined some address characters of every spatial feature based on their corresponding relationships, which had been existed in national economic census spatial database. To a certain vague address to be geocoding, this method would separate it into several address elements, and then located it by analyzing the comparability between those elements of the vague address and the address characters of every spatial feature. This method could promote the locating rate of the vague addresses.
