Synoptic Tables synthetise the information of several
relevés in each column of the table. They enable the comparison
of different vegetation units at the same time. A synoptic relevé
is essentially the same as a normal relevé, but without side
information (ecology, structure,...). In Quercus, synoptic relevés
maintain a list of original relevé codes that where used to build
them. This makes posible to build partitions from synoptic tables. Taxon
entry values in a synoptic table are presented in percentage format,
meaning the proportion of original relevés in the given synoptic
relevé where the given taxon entry was present. These proportions
can be displayed as percentages or classes (in roman numbers) but their
meaning remains the same. This display mode can be switched with the
menu option 'Change display mode' (F2).
The Synoptic Table Editor has almost the same options as the
Work Table Editor. It can reorder
rows and columns, filter entries, display taxon lists... Some of the
differences are listed here:
- Synoptic Releves are generated from Work Table Editor and
pasted into Synoptic Table Editor.
- Exporting a Synoptic Table for analysis does not need the Braun-Blanquet
scale transformation.
- One cannot generate a Synoptic Table from a table which is already
synoptic.
- Plotting options of Work Table Editor are not available in the Synoptic
Table Editor.
- Synoptic Relevés can be fused to become a new synoptic column.
- Synoptic Relevé names can be changed in Synoptic Table Editor.

New commands in Synoptic Table Editor which do not exist for
Work Tables are listed in the following table:
