The Victorian Land Cover Time Series provides a consistent through time, whole-of-state, spatial land cover data set for 7 epochs (1987-1990, 1990-1995, 1995-2000, 2000-2005, 2005-2010, 2010-2015 and 2015-19). The dataset uses Landsat satellite imagery and local calibration (or training) data. The most likely layers (one for each epoch) classify each pixel in to one of 19 land cover classes. The dataset provides additional evidence for use alongside other South Australian mapping products to measure and map native and non-native land cover types (although land cover types delineated are different between States).

Dataset Status:
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 As data validation and update processes are determined these layers may be superseded by subsequent versions.

Abstract:
The Victorian Land Cover Time Series provides a consistent through time, whole-of-state, spatial land cover data set for 7 epochs (1987-1990, 1990-1995, 1995-2000, 2000-2005, 2005-2010, 2010-2015 and 2015-19). The dataset uses Landsat satellite imagery and local calibration (or training) data. The most likely layers (one for each epoch) classify each pixel in to one of 19 land cover classes. The dataset provides additional evidence for use alongside other South Australian mapping products to measure and map native and non-native land cover types (although land cover types delineated are different between States).

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.

Positional Accuracy:
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.
Attribute Accuracy:
Complete for each land cover class defined.
Logical Consistency:
Not Known
