Title

Victorian Land Cover Time Series 

Alternate title

VIC_LANDCOVER_TS 

Purpose

This dataset can be used to inform spatial and temporal (5-yearly) summaries of the described land cover types for Victoria. The capture method and general nature of the classes are most useful for landscape and regional scale assessment (1:50,000 scale or smaller). Localised or paddock scale applications may encounter classification errors as a result of the modelling method that characterises spectral similarity. Note: it should not be assumed that this dataset represents a definitive land cover class at any given pixel, rather it aims to provide a consistent spectral description of land covers through time / between epochs. Associated datasets can be obtained by contacting the Data Authority where the class definitions, spatial resolution and five year time intervals are appropriate for a particular type of analysis or application.

Comments

Complete for each land cover class defined. 

Positional Accuracy

Comments

The positional accuracy is dependent on the original source of the imagery and the modelling process and where applicable exemplar data has been provided. Although the land cover models layers have not been projected from a Geographical Coordinate System the minimum area of mapping is approximately 25 m x 25 m (1:50,000) in line with the underlying Landsat archive outputs obtained from Geoscience Australia.

Missing Data

Comments

Dataset may be considered complete for the seven 5 year epochs (1987-1990, 1990-1995, 1995-2000, 2000-2005, 2005-2010, 2010-2015 and 2015-19). As data validation and update processes are determined these layers may be superseded by subsequent versions.
