All this information is encapsulated in an ST_Geometry value, implying that this value also needs about one MB disk space in the database.
所有信息封装在一个st_geometry值中,这意味着这个值在数据库中也需要大约1 MB的磁盘空间。
The complete definition of that geometry USES 0.9 MB disk space in the Spatial Extender internal format (which USES compression).
按照Spatial Extender内部格式,这个几何图形的完整定义要使用0.9 MB的磁盘空间(使用了压缩)。
If the geometry is encoded in the ESRI shape format, it actually requires 3.1 MB of disk space (see the Resources section for more information on ESRI shape format).
如果几何图形按照ESRI几何图形格式编码,那么它实际上需要3.1 MB的磁盘空间(请参阅参考资料一节,了解关于ESRI几何图形格式的更多信息)。
