| 摘 要： | 本文以全国第二次土地调查中的土地利用数据为例,根据国家标准GML 3.2规范,提出了基于GML的土地利用数据模型;针对传统的符合W3C标准的XML查询语言XQuery不能进行空间查询的问题,提出了一种在Saxon开源版本的XQuery引擎基础上扩展空间函数功能进而对GML数据进行空间查询的方法,并探讨了基于GML和XQ... |

| Abstract: | In this paper a land use data model which is based on GML and accorded to the national standards of GML 3.2 was proposed,and the data derived from the Second National Land Survey were taken for the example.Because it is difficult for traditional XML query language to query spatial data,a new spatial query method for GML data which is based on the open source version of Saxon XQuery Engine to extent spatial query method was raised in this paper,and then investigate the land use spatial object query model bas... |
