The traditional map information transmission theory only study common process of map information transmission and the theory study a little architecture of the map information transmission under the digital mapping.The integration of theory and practice is not tightness.This paper presents an rchitecture of the map information transmission under the Digital Mapping,which contains physical layer,logic layer,concept layer and realization layer.The paper discusses the protocols,interfaces and services between layers.Based on the theoretic results above,a reference model of data acquisition and processing is established,control protocols in the process of Map information transmission are analyzed and a solution to information loss and distortion is also proposed.The reference model has been acquired good effect on the system of data acquisition and processing.
