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

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
