摘要
曲线是GIS空间数据的重要空间目标之一,也是描述面和体的基础。当前的GIS产品中,描述GIS空间曲线使用的是数学和插值方法,并使其可视化。用蚁群算法对GIS空间曲线进行描述,使其具有智能的性质。通过理论分析和模拟实验,表明用蚁群算法描述GIS空间曲线乃至其他空间目标,是可行和有效的。
Curve is one of important spatial objects on GIS spatial data.It is the base of describing surface and body.In current GIS products,GIS spatial curve is described by mathematics and interpolation. Its visualization is implemented in computer.In this paper,GIS spatial curve is described by ant colony algorithms.This method is intelligent.Through theory analysis and simulation experiment,feasibility and availability of the method are indicated by the resuh.
