Recently do Baidu map API-related application development, need to overlay their maps to Baidu map above, to see the official Baidu API description of the JavaScript section, do not have a good explanation of how to cover the interface.

Looking for relevant articles on the Internet to see the next, (http://www.makaidong.com/jz1108/archive/2011/10/08/2202239.html) This article to achieve this Chettu function, but the latest Baidu The highest scaling level of 19, the project needs, but only their own to write a map development tools.

Refer to another article by the same author (http://www.makaidong.com/jz1108/archive/2011/07/02/2095376.html), specifically speaking of Baidu coordinate system development.

Program is implemented in Java Web, struts 2 file tag and simple JS call.
