Abstract

The Multi-source spatial data distribution is based on WebGIS, and it is an important part of multi-source geographic information management system. a new multi-source spatial data distribution model is proposed on the basis of multisource data storage model and by combining existing map distribution technology, The author developed a multi-source spatial data distribution system which based on MapGIS K9 by using this model and taking full advantage of interfacecode separating thinking and high efficiency characteristic of .net, so high-speed distribution of multi-source spatial data realized.

Summary

Introduction

The content of map distribution study includes: the ways of map distribution [1,2], the technology of map distribution [3-5], how to use current soft middleware to develop a map distribution system. These studies mainly focused on a single map distribution and they do not describe the multi-source spatial data distribution in detail. A multi-source spatial data distribution model which based on multi-source data storage model is proposed in the paper, and as an example of the model, the author developed a multi-source spatial data distribution system by using MapGIS K9 middleware, which achieve high-speed distribution of multi-source spatial data
