Since 2008, China has fully adopted CGCS 2000 as its unified coordinate system. CGCS 2000 (China Geodetic Coordinate System 2000) is similar to LL84 but has a slight deviation. At present, all Chinese users must use coordinate offset to realize each data interaction. China is one of the countries with the most InfraWorks users. Please provide the CGCS 2000 coordinate system and relevant projected coordinate systems to help users directly use the accurate coordinate position in InfraWorks. Thanks!
