NVIS Origins - Contents
• NVIS Origins• Stakeholders• NVIS Framework• NVIS Data Types• Spatial Data Compilation• Non-spatial Data Compilation (2 slides)
– Vegetation Data Model• Integration• NVIS Version 1 Products
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
NVIS Framework
11. Derived Products
2. Data Documentation Attributes and Dataset Boundaries
10. ANZLIC Metadata
9. Vegetation Condition Attributes
1. Data Management and Compilation Standards.
8. Site Attribute Standards
4. Vegetation Description and Map Unit Attributes
3. Vegetation Spatial Data
6. Checking Rules
5. Detailed Vegetation Attributes
7. Taxonomic Attributes
NVIS Data Types
• Manage 2 main data types– Spatial (polygon)– Non-spatial attributes
• NVIS Products– Subsets of detailed data– Combined spatial and non-spatial– Raster or vector
• +/- plot data in background

Next Phase• Governance by Executive Steering Committee for
Australian Vegetation Information– State, Territory & Aust Govt representatives– Continues to date
• Collaborative technical work– Motivation includes capacity building for each
custodian and information exchange– Focus on size (organisation & performance) and quality
issues
Collaborative Technical Work (1)
• Reviewed Framework– Revised attribute definitions– Restructured database– Agreed QA “rules”– Documentation
• System Development– NVIS database module in each (8)
state/territory– Developed XML Transfer System– Implements QA checks and rules– Spatial storage (ArcSDE)

Current Phase - Contents
• Current Phase
• SoE 2006 Reporting
• Native Vegetation in Australia• Booklet and CD• Web site
Current Phase• Re-supplied NVIS
– Revised content by states & territory custodians– Attributes via XML Transfer System– Version 3.x products– Analyses for Australia’s State of the Environment 2006
• Promoting NVIS, esp. via hard copy– Brochures, banners, poster/map– Articles and seminars– Booklet and CD– Improved web sites
• ESCAVI is developing indicators for Monitoring & Evaluation of Natural Resource Management programs– Vegetation Type and Extent– Vegetation Condition
SoE 2006 Reporting
Booklet & CD
NVIS: The Future
• Ongoing improvement of the framework, infrastructure and inventory– Ongoing collaborative technical work
• Reporting on – change in the extent of NVIS vegetation types over time– native vegetation condition
• Web services– Tracking NRM indicators– State/Territory mapping– Vegetation portal
• Linkages with other national NRM themes– Likely new requirements at different scales and classifications
