Research on Coordinate System Conversion Technology of CGCS2000 Geospatial Data in Hunan Province
The CGCS2000 coordinate system is the current legal geodetic system in China,which is of critical for unifying the national reference frame and promoting the geographical data sharing and exchange.For transformation from former coordinate system to CGCS2000 of the provincial geographical spatial data,it not only requires high accuracy,but also more issues such as large data amount,wide region and complicated formats.With the real data from Hunan Province,China,the approach consists of data collection,transformation parameter calculation,software designs,quality verification and data release,is presented.With the unique Bursa model parameters,batch processing and quality checking modes,all the geographical spatial data are transformed.
