NVIS Origins

• National Land and Water Resources Audit
• 1997-2001
• Theme 3 Vegetation
• NVIS framework and system developed as a means of
  compiling heterogeneous vegetation datasets
  collected over the last 50 years
• For regional and national assessments

Stakeholders

• Partnership of State, Territory and Australian
  governments
• Users of NVIS products include
• Policy makers
• Natural Resource Management (NRM) region
  vegetation managers
• Researchers and Educators
• Public

• Non-spatial attributes
• NVIS Products
• Subsets of detailed data
• Combined spatial and non-spatial
• Raster or vector
• /- plot data in background
