China on Sunday launched a new high-resolution remote sensing satellite capable of providing stereoscopic imagery, state-run media said, marking another important step as Beijing seeks to reduce reliance on foreign technology in topographic mapping.

A rocket lifted off from the Taiyuan Satellite Launch Center in northern China at 11:22 a.m. local time, carrying the Gaofen-7 high resolution satellite into its designated orbit, the state-run China Central Television (CCTV) said, citing China National Space Administration.

Gaofen-7, a submeter resolution optical satellite, boasts the highest mapping accuracy among its domestic peers, and is able to map China and even territory belonging to other nations stereoscopically with a margin of error of less than a meter, according to CCTV.

The satellite, which will be used for land surveys, urban planning and statistical investigation, will help end China’s reliance on foreign imports in high-resolution stereo mapping, CCTV added.

The purpose of China’s satellite remote sensing project — the Gaofen series — is to help build an all-weather, 24-hour, global Earth remote sensing system by 2020 capable of monitoring the ground, atmosphere and oceans, according to CNSA.

The Gaofen project, one of the 16 major projects that are key to the nation’s scientific development, is also aimed at comprehensively boosting China’s self-reliance in accessing high-resolution Earth observation data.
