A description of the data to replicate as well
as various settings that define how the data will be replicated. For
example, you can set a spatial filter, set the replica model type, and
specify whether or not to include related data. See
the GPReplicaDescription class
for more information. |

the output format and whether or not the output will be compressed. See

Return Value
A GDSData object.
Remarks
The ExtractData method can be used to extract and download a spatial subset of data from a specified set of datasets. Only datasets that are accessible by the database user associated with the geodata service are accessible. The data to be extracted is specified by a ReplicaDescription object. Both vector and raster data can be extracted. A separate attribute query can be applied to each table or feature class. Related records may be fetched as part of the extract.
