Abstract: Polygons showing the extent of wetlands in Victoria prior to European settlement. Wetlands are classified into primary categories based on water regimes.
The polygon boundaries were derived from digitizing marked up aerial photography interpretation.

Purpose: WETLAND_1788 is one of two layers designed to document changes over time in the nature and extent of wetland environments in Victoria. This layer is directly related to WETLAND_1994 via the use of a common wetland identification system. It is a simpler layer than WETLAND_1994 in that there is no delineation of sub areas within wetlands.

Stored Data Format: DIGITAL Arc/Info Revision 7 Librarian layer
Available Format(s) Types: DIGITAL - All major formats available
Lineage: Primary
Positional Accuracy: Precision: 10m to 100m Determination: Deductive estimate. Ad-hoc comparisons with 1:25,000 layer data and various sorts of imagery indicated good correlation in terms of shape and size but with errors of the order indicated above in terms of position and/or rotation. When resources permit, the 1:25,000 library hydrology and roads layers should be used to identify layer inconsistencies which may indicate specific wetlands which require translation, rotation or boundary modifications.
Atribute Accuracy: The classification scheme used is based on photo interpretation and ground surveys carried out by Departmental research staff under the direction of research scientist Andrew Corrick.
Logical Consistency: The Wetland Mapping System includes processes for checking: *node, label and intersect errors. *validation of category codes prior to insertion in the library.
Data Source: The data has been prepared primarily from standard Survey and Mapping Victoria photo runs with some local revisions based on other historical sources.
Completeness: All wetlands with an area of 1 hectare or more should be present.
