ArcGIS Python又一个dug，平时不建议大家使用地理坐标系

importarcpy

# 创建空间参考

cgcs2000=arcpy.SpatialReference(4490)  # CGCS2000

# 创建点要素类

fc_name="Cities_CGCS2000"

arcpy.CreateFeatureclass_management(

    out_path=arcpy.env.workspace,

    out_name=fc_name,

    geometry_type="POINT",

    spatial_reference=cgcs2000

)

cgcs2000.XYResolution=0.000000000899322

cgcs2000.XYTolerance=0.000000008983153
