Google map and Yahoo map have released their own APIs, which can be used for free. It feels very good. You should think about some problems (note: microsoft's mappoint already has a paid web service, and the desktop version can also be embedded into the application.Program). Google map API is really simple. It only takes two hours to read the document carefully and you can develop it without having to know any professional map knowledge. The API is Ja

Preliminary understanding A map consists of layers, elements, and styles. There are N layers on the map, and there are n elements on the layer. Each element can store points, lines, and surfaces, and each element can set a style, if an image or text is displayed, you can create an mxml component and set it to the element. Both the surface and line are composed of points.Add point 1. initialize the graphicslayer. 2. Obtain the coordinate point and mappoint
