关于地理实体编码设计和应用的研究

The Design and Application Research On Geo-entity Code

本文以考虑地理实体编码在地理空间数据更新中的应用为出发点,对地理实体编码的设计进行了初步研究。通过分析和试验建立了一套统一的编码规则,使之能适应于数据生产中要素的自动编码,并为实现要素快速定位、变化要素自动级联更新等应用创造有利的技术支持。

Abstract In this paper, the design un geo-entity adapt to the data in the applications such as the in order to consider geo-entity encoded in the spatial data updating application as the starting point, code were studied. Through the test and analysis to establish a unified set of encoding rules, they can production of automatic coding for the elements, and create a favorable technical support for many realization of fast positioning and automatic cascade updating.
