摘要
以陕西省土壤分类信息系统中的土类数据制图为例,分析了基于Google Earth(GE)的专题地图的制图原理与技术,提出了一套基于GE的一般地理专题图的制图技术流程,并讨论了其关键技术。指出了GE制图工具目前存在的两个缺陷,提出了相应的解决方法,并介绍了陕西省土壤分类信息系统中GE制图结果和应用方案。
Taking Soil Taxonomy Information System of Shaanxi Province as an example, the thematic mapping method and technology based on Google Earth （GE） are analyzed. A general thematic mapping flow based on GE is suggested. Details of mapping process and key techniques are discussed at each step of the mapping flow. Two defects of GE mapping tools are pointed out and its resolution is proposed. Mapping resuits and application mode of Soil Taxonomy Information System of Shaanxi Province are presented.
