随着人们对三维信息需求的不断增长，我们需要一个健壮的三维空间对象数据模型来满足不同应用的需求。为此，ISO/TC 211和OGC进行了一些研究，其中ISO 19107[2]的数据模型和KML[6]的数据模型是最重要的。ISO 19107的数据模型提供了强大的三维空间信息表达能力，为全三维实体对象提供了复杂的模型。GML[4]是基于ISO 19107的空间数据模型。然而，这种数据模型有一个严重的缺点，即GML中的数据量很大，并且由于这种数据模型的复杂结构，ISO 19107的实现是困难和繁重的。
With the recent increase of demands for 3D information, we need a robust data model of 3D spatial objects to meet the requirements from diverse applications. For this reason, several studies have been done out by ISO/TC211 and OGC, among which the data model of ISO 19107[2] and the data model for KML[6] are the most important ones. The data model of ISO 19107 provides a strong expressive power of 3D spatial information with a sophisticated model for full 3D solid object. And GML[4] is based on the spatial data model of ISO 19107. However this data model has a serious drawback that the size of data in GML is large and the implementation of ISO 19107 is difficult and heavy, due to the complicated structure of this data model.
