摘要:
地理信息图示中的很多图形要素均是随机曲线,如边界线、河流、海岸、道路等。在地理信息的计算机处理过程中,若要真实描述这类曲线将非常消耗存贮容量,也极大地加重内外交换的负担。该文采用近似折线来定义这类曲线,在成图时对折线的边实施随机化处理,从而构造出模拟曲线。这种方法在地理信息的随机曲线图示中非常有效,已被应用于水利工程信息管理之中
Abstract:
In geog raphical informat io n ( GI) draw ing , there ar e many random curves, like bo undary lines, reiver s, coast s and ro ads, etc. During the computer processing of GI, it is capacity-consumed to describe these curves t ruly , and the data ex chang ing between internal and external memory may be t ime-consumed. The method descr ibed in this paper used the broken line to define this kind of curv es, implement ing random pro cessing fo r ever y edg e of the broken line, and simulat ing the random cur ves. This method is helpful to cr eate the r andom curv es in hydr olog y and has been applied in the info rmat ion manag ement of w ater conservancy pro ject .
