基于ArcGIS与ArcObjects的线性参考系统的建立与应用

公路,铁路,河流等线性物体通常用沿线路的相对距离来确定线路上点或线的位置,而线性物体在地理信息系统当中一般用二维坐标系统来模拟,用常规的方法根据相对位置计算位置点的x、y坐标有一定的误差.本文重点介绍了线性参考系统的概念,并提出了基于ArcGIS的线性参考系统的建立与基于ArcObjects的线性参考系统的开发应用相结合的解决方法.

CREATING AND DEVELOPING LINEAR REFERENCE BASED ON ARCGIS AND ARCOBJECTS

Linear features such as roads, railroads and rivers normally use a relative position along routes to describe the location of points or lines, but they are typically modeled using a two-dimensional xy coordinate system in GIS. Errors would be produced during the process of calculating xy coordinates based on the relative position using traditional methods. This paper introduced the basic concepts of linear referencing, and proposed an easier way of creating and developing linear reference based on ArcGIS and ArcObjects to solve the problem.
