在分布式GIS系统中实现非矢量地图经纬度定位

Locate a site' latitude and longitude on the non-vector Map in distributed GIS

提出了基于DCOM分布式算法在由传统地图扫描成的JPEG格式地图上实现经纬度定位的方法，并且详细论述了该方法的原理和简单应用。

This paper provides a method based on DCOM arithmetic to locate a site' latitude and longitude on the JPEG Map which is attained by scanning traditional map,and discusses the principle and application of this means in detail.
