BEIJING - Access to and usage of Chinese geographic data have both improved with the establishment of three key platforms, according to a conference held by the National Administration of Surveying, Mapping and Geoinformation (NASMG) on Monday.

The three platforms include an online city management network, a public map database and geographic condition monitoring used by the country's decision-makers.

The city management network is used to provide information about specific cities, including traffic jam alerts and GPS data. The NASMG said 230 cities in China are now part of the network.

The 2011 version of the public map database has been updated with geographic information covering almost half of China, according to the NASMG. The database's maps have garnered nearly 200 million views from users in 216 countries and regions worldwide, the NASMG said.

On August 26, China announced that its cartographers had finished constructing a database containing "comprehensive geographic information" after creating detailed maps of 2 million square km of land in China's vast western region.

A plan for national surveying and mapping during the country's 12th Five-Year Plan period (2011-2015) was published on Monday.

According to NASMG officials, China will make efforts to set up a high-precision, multi-functional 3D mapping system covering basic geographic information at the national, provincial and prefectural levels before 2015.
