DescriptionExtent of urban areas adjacent to rivers
Input data
Lineage
An assessment of the extent of urbanisation overlying or adjacent to freshwater-dependent ecosystems in Tasmania was undertaken using the TASVEG data layer (Version 0.1 May 2004). TASVEG codes denoting urban and semi-urban development: Ur (rural miscellaneous), Uc (built-up areas) and Ue (permanent easements), were selected from the TASVEG data layer to create an urbanisation base data layer.
An urbanisation score was assigned to river sections using rules provided below.
Data limitations
As per the TASVEG data set.
Date createdJuly 2004

Assigning values to ecosystem spatial units
Using the urbanisation spatial data layer, each river section was assigned a score (RS_URBAN) indicating presence (0) or absence (1), based on whichever was present along the majority of the river section length.
