Description of GIS spatial curve based on ant colony algorithms

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 result.
