China unveils its own version of Google Earth

BEIJING,  (Reuters) – A Chinese government body has  released its own online mapping service, designed to compete  with Google Earth’s popular satellite mapping service, that  could spell more trouble for Google’s services in the mainland.

Google and China have been at odds since last year, when a  serious hacking attack originating from China prompted Google  to ultimately withdraw its search service from the mainland.

“Map World” was unveiled by the State Bureau of Surveying  and Mapping yesterday, and can be accessed via  www.tianditu.cn. The home page features an expansive view of  the Great Wall of China, capped by clouds in the shape of the  continents.

Google had not applied for a Web mapping licence in China,  the English-language paper said, but Google’s mapping service  is accessible from computers on the mainland.
Regulations issued by the bureau in May required companies  providing online map and location services to apply for a  licence. In order to apply, firms would have to keep map  servers storing data within the country.

Google said at the time that it was studying the new rules,  which gives China the right to shut down providers that fail to  qualify for a licence.

Google’s video-sharing site YouTube and photo service  Picasa are both blocked in China, and its Google docs  application is sometimes difficult to access. Searches  originating in China are now directed to its search engine  based in Hong Kong.
Google does not keep servers in mainland China.

At least some of Map World’s high-resolution images of  central Beijing appear to have been taken on Oct 1, 2009, when  streets were cleared for the tanks and floats of the National  Day Parade, which are visible on the street.

Map World only provides high-altitude images outside China,  with the other side of the Chinese-North Korean border a stark  white blank once a certain resolution is passed. Other  countries also turn up a blank page at close resolution.

Taiwan, which China claims as a renegade province, cannot  be viewed at the same resolution as the mainland.

Much mapping in China is still subject to state-secrecy  restrictions, creating headaches for mining companies unable to  source high-resolution deposit maps, and even for hikers.
