So the process to achieve the integration of all the collected data is quite simple:
- First you ask the users that are
participating on the assessment to
export the data as an XML file
(actually the results of the export
is a ZIP file containing the
collected data as XML files inside
it)

-
Then they should send the exported
files to a shared network or dropbox folder or an e-mail
address
so that everyone has access to them.
You should probably ask the
users to rename the exported files
to something meaningful like the
regions they have assessed or the
plot id ranges, otherwise the
standard name of the exported ZIP
file is
collectDataExport_FULL_ZIP_WITH_XML.zip
which is not so descriptive if you
have 20 files like it.
-
Finally the last step is to import
the data. You can just go to
Tools->Data Import/Export->Import
data from XML and after that select
the files (the dialog allows you to
select multiple files) that
contained the exported data.

So know all the data that was collected from the different computers is integrated on the database of the computer where the data was imported. Obviously you can do this import process on one or several of the PCs.
Afterwards you will be able to start Saiku (using Tools->Start Saiku Analysis) and analyze all of the collected data.
IMPORTANT!!! The order in which you import the data matters. If you have been using a province or a set of data as the training plots for the users make sure to import the file that contains the " good data" for those plots last! If you then are prompeted if you want to overwrite the data on the database with this data click yes, as you know that this last file contains the data that was assessed correctly and not data that was just filled as a test.
IMPORTANT 2!!!! If you want to make sure that there are no data overlaps you should probably delete the database file ( see this answer ) after you have completed the training of the users and before you start the real assessment.
