This sentence is not original. I am a gis major, and the company once considered developing with api, but I gave up because of many restrictions. This author is quite familiar.

Google Maps API: Based on Google Maps, Google Maps API can embed Google Maps into web pages using JavaScript. API provides a large number of utilities to process maps and add content to maps through various services, thus enabling users to create powerful map applications on their own websites. Google Maps API supports traffic maps and satellite maps, with Chinese language version, and its landmark file KML format has become the standard format of online maps, and both Google Earth and Google Maps support KML. It is widely used at home and abroad. When it comes to the application of Internet maps, Google Maps API is basically essential.

Microsoft virtual earth API: an API based on virtual earth, English version. Its examples and display effects are very rich. After previewing the effect, you can view the related source code. Unfortunately, the development of China map is not supported at present.

Yahoo Map API: Based on Yahoo Map, like Microsoft Map, it only supports English, but does not support the development of China Map. Yahoo Maps provides three development interfaces based on Flash, Ajax and map pictures, with complete functions and good display effect.

MapABC API: A domestic map supplier based on MapABC. China data of Google Maps uses MapABC, but its API interface is different from that of Google, and the API is not as open and flexible as Google Maps API.

I want the map API: based on 5 1 map, one of the characteristics of the map I want is to provide map data download, which can realize local desktop maps, but its map data capacity is several hundred megabytes.

We have made technical research on several mainstream map API service providers in the market: Google map service, MapABC map service, Microsoft map service and other map services, and provided reference for us to choose a more suitable map service provider according to the research summary results.

1. Research content plan

The main contents of this technical investigation are:

1. How to use various MAP-API? MAP-API examines the development efficiency of the system, such as the rationality of use and packaging.

Several aspects of convenience.

2. Study the functions of various map-APIs in the early stage, and study the function limitations of various map-APIs in the free version, aiming at free and charging.

Similarities and differences in edition, charging strategy and price

3. Complete a simple calling example with the free version API of each MAP-API, which is also convenient for the code level of each API.

The experience of using.

Step 2 study the details

2. 1 Google Maps API survey

2. 1. 1. Introduction and evaluation of main usage methods:

Types and application scenarios of Google Maps API;

A.Google JavaScript map API: embedded Iframe presentation form, suitable for general Internet application systems, with

Client system loaded by standard mainstream browsers. Supported browser types: ie, firefox, safari, google chrome. use

You can develop standard Java scripts to integrate Google Maps space, which is similar to the standard Google Maps function.

B.Google Maps API(FLASH version): FLASH presentation form, developed with flex, suitable for standard browser loading.

The client system is based on. '

C.Google Static Map API: Picture: Picture presentation form, the use is blocked by GFW for some reasons, so it is the same.

Ditu.live.com, the Microsoft Map API service, is ringing. I hope that similar incidents will happen less in the future.

Part of the information comes from the Internet, for the reference of developers only!
