A method for building thematic map of GIS based on Google Maps API

To solve the factual problem that Google Maps API can not provide directly the function of building range thematic map of GIS, this paper builds indirectly range thematic map by means of the combination use of the other class and methods provided by Google Maps API and XML technology, ArcGIS spatial data disposal technology and so on. The build idea, method are discussed in this paper in detail. To validate the idea and method proposed in this paper, we drew the range thematic map of permanent population density in 2004 year in 18 districts and counties of Beijing. The drawing results are better. The realization of the above function can not only solve the problems I encountered, I believe it is possible to provide a reference on the ideas for the readers, who need to create range thematic map based on Google Maps API.
