SPOT Woody Change Data (5-10m) 2008-2013

These layers show areas of woody vegetation change based on the analysis of multi-date SPOT5 imagery. The analysis has been done for the period 2008-2009, 2009-2010, 2010-2011, 2011-2012 and 2012-2013.

The woody vegetation change is mapped using the SLATS (Statewide Land and Tree Survey) method which applies an automated change analysis process followed by visual interpretation of the results by experienced image interpretation staff. Change codes reflect the interpreted cause of woody vegetation change. Each change era has a single statewide point and polygon layer derived from approximately 310 SPOT scenes covering NSW.

Vector point format is preferred for analysis to prevent double counting when undertaking regional calculations. Points can only fall into a single region unlike raster pixels which can sit astride a vector boundary. This often occurs with analysis based on vector regions such as Local Government Areas or Bioregions.

The woody change data is also used for vegetation compliance analysis. Change statistics are available for all change periods.
