地形图自动分幅模型的设计与实现

Design and Implementation of Automatic Construction Model of Topographic Map Framing

地形图分幅空间数据库常规构建方法对操作者要求较高,步骤烦琐,效率较低。本文基于ArcGIS Model Builder设计了一套地形图自动分幅模型,实现了自动构建适应研究区范围的多种比例尺地形图分幅空间数据库的功能。该模型可以很好地实现共享与复用,减少重复性劳动,提高数据处理效率,具有较好的推广意义。文中对模型设计流程进行了详细描述,对关键的工具和变量做了说明,可为同行者基于ArcGIS Model Builder设计出满足特定任务要求的模型提供参考。

The conventional framing method of the topographic map spatial database has higher requirements on operators,complicated steps and lower efficiency.Based on the ArcGIS Model Builder,this paper designed a model for automatically constructing topographic map framing,and realized the function of automatically constructing a spatial database of multiple scale topographic maps for the study area.Sharing and reuse of the models can reduce repetitive work and improve data processing efficiency,which was suitable for promotion.The model design process was described in detail in this paper,and the key tools and variables were described,which could provide reference to design a model that meets the specific requirements based on ArcGIS Model Builder.
