Table 3. Evaluation results 
According to the evaluation results, there were two 
websites whose degree of membership was above 0.90 
like Baidu Map and Google Map. The degree of 
membership between 0.80-0.90 was MapBar, SoSo 
Map, Sogou Map and MapABC, followed by 51ditu, 
Aliyun, Bing Map and MapWorld. A conclusion can 
be drawn from the evaluation that online map service 
market in China have reached a certain scale, and the 
websites were not weak to than foreign websites, even 
ahead of them in some areas.Baidu Map owns the 
largest amount group based on the on the brand 
influence in the whole searching market in China and 
its own technical advantage. Also, its interaction 
accords with the intellection habit mostly. Google 
Map has advantages in data, technology and interface, 
especially its image data and street view, but its 
service is not stable times to times, causing users lost 
because of slow response. As the traditional online 
map service supporters in China, MapBar, MapABC 
and Sogo Map integrated tourism, repast and 
entertainment, which is close to people’s daily life. 
Based on the technical advantages in response and 
interaction, SoSo Map, as a rising star of the online 
map service market will have a bright future. Those 
Website in the third grade are still in the development 
Stage, such as Map World, which combines data 
authority and diversity, but its searching experience 
423 
performed poorly. But its vitality relies on application, 
and with the development of the civil high-definition 
survey satellite "ZY 3 ", the frequency of data updates 
and data quality will be further improved. 
4 CONCLUSION AND DISCUSSION 
The nature of online map is to digitalize the real world, 
and support more serialized information than it. Now, 
the industry of online map service is going along this 
route steadily, and has made great achievement. 
During the comprehensive evaluation of online map 
service, the multiple-grades and fuzzy comprehensive 
evaluation method was used, which can process the 
fuzziness between factors objectivity and decrease the 
subjectivity and blindness in the procedure, so as to 
ensure the reliability and accuracy of the evaluation 
results. The purpose of evaluation is not to rank all the 
websites, but to analyse the problems through the 
evaluation results, and a clearer direction for the next 
development step can be pointed out, which provides 
important practical and theoretical value to the 
competitive industry.
