【摘要】 数据转换是GIS工程建设中的一个十分重要的内容,传统的方法往往只是进行数据格式的转换,忽略了空间数据之间的内在联系,本文将语义映射和空间操作相结合,实现空间数据和属性数据的重构,从而实现异构数据的快速转换。更多还原

【Abstract】 Data conversion is a basic and important work in GIS engineering. Traditionally, only the data format is converted, and the inner relationship of data is missed. The semantic mapping and geospatial operation are integrated together in geospatial data conversion in this paper. The result shows that this method is very efficient for geospatial data conversion.更多还原
