| 摘 要： | 为避开专业GIS软件操作的复杂性,以一个基于MapObjects的校园地物资源管理系统的图层处理模块为例,探讨了应用型GIS中矢量图层创建、图层坐标系定义、图元绘制、图元编辑、图元删除等功能的具体实现方法。通过编程,用户可以轻松完成对矢量图层的各种加工处理,大大提高了用户对图形数据的处理效率。实验结果说明,MapObjects组件特别适合处理地理信息,具有强大优势。 |

| Abstract: | To avoid the complexity of special GIS software,this paper,taking the GIS layer processing module in a campus ground object resources’ administration system based on MapObjects for instance,discusses the method of how to realize the function of GIS layer’s processing.The effective programme can help users to complete the processing of vectorgraph layers easily,improve the efficiency greatly.The experiment results showed that the MapObjects’s functions are very suitable for processing geographic information,and is of strong advantage. |
| Keywords: | MapObjects geographic information system vectorgraph layer coordinate system |
