摘要
GIS互操作研究是当前地理信息系统研究的热点。OGC制定的GML标准给互操作领域带来了新的契机,它是解决多源、多层次、多维地理空间信息互操作的简单而有效的途径。本文首先分析了GIS互操作,接着提出了基于GML的GIS可互操作模型,最后,具体阐述了地理数据的GML表示方法。
Research on GIS interoperability is a ch aracteristic in GIS study currently.OGC’s (OpenGIS Consortium)GML(Geography Mar kup Language)brought a new chance for us,it’s a effective and simple approach t o solve geographical spatial information(GSI) sharing and interoperability,so re search on this field have strong significance.This paper is discussed the model of GIS interoperability,geographical spatial information data is expressed by us ing GML,and some example is illustrated.
