Geospatial database access interface
1 Scope
This standard specifies the data access object model and interface geospatial database to meet this standard interface for spatial data providers
Make provision for loading and unloading.
This standard applies to access via standard interfaces or share geospatial database applications, focusing on the user and the data from the data provided
Describe the perspective of access to the object model and interface, does not apply to specific content coordinate reference system and metadata.
