Vegetation Trend Classification For South West Agricultural Zone 1990-2021

A one-band summary of linear vegetation cover trends from 1990 to 2021, classified into five categories for the south west agricultural zone of Western Australia. The dataset was created by Landgate from the Vegetation Trend dataset. It provides a simplified, numeric interpretation of vegetation density changes over the 31-year period.

Use Cases

• Analyze the spatial distribution of pixel values (1-5) to map areas of major vegetation increase or decrease in the agricultural zone.
• Model long-term vegetation trend classes as a function of climate or land-use data for the 1990-2021 period.
• Use the five trend classes to identify regions of stable vegetation (class 3) versus those with significant change for conservation planning.

Strengths

• Provides a 31-year temporal coverage (1990-2021) for analyzing long-term vegetation trends.
• Offers a simplified, one-band classification with five distinct, numerically defined trend classes for easier analysis.
• Derived from the authoritative Vegetation Trend dataset by Landgate, the state's land information authority.

Limitations

• Limited geographic scope, covering only the south west agricultural zone of Western Australia.
• Trend classes are based on numeric changes in a linear index without ground-truth ecological interpretation, requiring cautious application.
• Data is delivered via service formats (WMS, ArcGIS Server) rather than direct tabular files, which may complicate quantitative analysis.
