BEIJING, June 22 (Xinhua) -- China launched a series of "red" mapping services online on Wednesday to mark the revolutionary bases and historic sites across the country.
The country's surveying and mapping institutions have launched 10 national and local systems of online mapping services marking the "red" historic sites, according to a statement issued by the National Administration of Surveying, Mapping and Geoinformation Wednesday.
Historic sites and important events in China's revolution are displayed with three-dimensional animations and pictures in the systems to provide users with more direct and multi-dimensional images, said Min Yiren, deputy-director of the administration.
The services are available at the administration's website, www.sbsm.gov.cn.
Moreover, a series of printed maps focusing on the revolutionary sites and history has been published to celebrate the 90th anniversary of the founding of the Communist Party of China (CPC), which falls on July 1.
