Abstract:
This is a lookup table containing details about the input datasets, which were compiled into the main NVIS. Details include dataset title, scale and creation dates for the original attribute and spatial data.

It is intended to accompany the NVIS spatial key layers, which contain the spatial footprints of the two main themes, viz:
- National Vegetation Information System (NVIS) Version 4.1 - Australia - Key Layer for Present (Extant) Native Vegetation Data
- National Vegetation Information System (NVIS) Version 4.1 - Australia - Key Layer for the Estimated pre-1750 Native Vegetation Data

Instructions:
- Join DATA_SET_NUMBER in the table to DATA_SET_NUMBER in the respective spatial key layer, above. (Note that field names are all truncated to 10 characters in shapefiles and DBF tables derived from the main NVIS data - e.g. DATA_SET_NUMBER is truncated to DATA_SET_N.)
- (Optionally) use the following layer files for attribute legends in ArcMap:
- nvis4_1_key_scales.lyr for MAP_PUBLICATION_SCALE
- nvis4_1_key_att_sources.lyr for ATTRIBUTE_ORIGIN
- nvis4_1_key_spatial_sources.lyr for SPATIAL_ORIGIN

Data Quality Information:

Scope of quality information: dataset

Lineage:
The NVIS DATA_SET Oracle table has been in existence since the original NVIS in 2000. Most content was provided by the (mostly state and territory) custodians of the original datasets.

The content has been progressively updated for NVIS versions 2.0, 3.0, 3.1, 4.0 and (this version) 4.1.

The NVIS VERSION_USAGE Oracle table was created in September 2007, and updated to be complete for version 4.1 in March 2012.

Source data acknowledgements:
Please acknowledge the data suppliers listed in the Abstract.

Data quality report - Absolute external positional accuracy:
N/A

Data quality report - Attribute accuracy:
Most of the attributes are self-explanatory. Attributes from the NVIS DATA_SET table are documented in ESCAVI (2003) and are marked below with an asterisk (*). Others are simplified from documented DATA_SET fields or are from the NVIS VERSION_USAGE (new) table. Missing numeric data is indicated by "-9999".

Attribute allowable values and/or examples:
- DATA_SET_NUMBER*: Standardised NVIS dataset number.
- DATA_SET_NAME*: Standardised NVIS dataset title.
- VEGETATION_THEME_CODE*: E = extant/present vegetation; P - pre-1750 vegetation; and B= both.
- VERSION_NUMBER: Examples: 2.00, 3.00, 3.10, 4.10
- FOOTPRINT_USED: WHOLE/PART/NIL/UNKNOWN - summary as to whether the whole footprint of the source dataset is used or not.
- ATTRIBUTE_ORIGIN: STATE_TERR_NVIS OLDER_NVIS NVIS_OTHER GAP-FILL DATA N/A
- SPATIAL_ORIGIN: STATE_TERR_NVIS OLDER_NVIS NVIS_OTHER GAP-FILL_DATA N/A
- MAX_NVIS_LEVEL: Lookup , viz: 0 = dummy (for gap-filling) 1 = level1_class 2 = level2_formation 3 = level3_broad_floristic_formation 4 = level4_sub-formation 5 = level5_association 6 = level6_sub-association
- MAX_NO_VEG_DESC: 0,1-6 (-17) Numbers > 1 indicate that mosaics are present.
- PROPORTIONS_PRESENT - Y, N, N/A - summary for the whole input dataset
- MAP_PUBLICATION_SCALE*: Scale at which the map/dataset was published.
- START_YEAR_ATTRIBUTE: Year of earliest field surveys underpinning the NVIS vegetation descriptions.
- END_YEAR_ATTRIBUTE: Year of last field surveys underpinning the NVIS vegetation descriptions.
- START_YEAR_SPATIAL: Year of the earliest imagery used in the mapping.
- END_YEAR_SPATIAL: Year of the latest imagery used in the mapping.

Data quality report - Conceptual consistency:
Several attributes are well organised, whilst others require further editing - see Completeness.

Where a dataset has a value of VEGETATION_THEME_CODE="B", the attributes are generally correct for the "extant" vegetation theme, but possibly not for the estimated pre-1750 theme. In this case, footprints for the same dataset could be different in the two themes.

Note that some datasets in this list (e.g. #332) do not have a spatial footprint in the key layers, since these would add unacceptable spatial complexity to what is meant to be a guide to the data, not real vegetation data.

Data quality report - Completeness:
The following fields are complete for NVIS Version 4.1, viz:
- DATA_SET_NUMBER
- DATA_SET_NAME
- VEGETATION_THEME_CODE
- VERSION_NUMBER
- FOOTPRINT_USED
- ATTRIBUTE_ORIGIN
- SPATIAL_ORIGIN
- MAX_NVIS_LEVEL
- MAX_NO_VEG_DESC
- PROPORTIONS_PRESENT
- MAP_PUBLICATION_SCALE

The following fields need updating and further editing.
- START_YEAR_ATTRIBUTE
- END_YEAR_ATTRIBUTE
- START_YEAR_SPATIAL
- END_YEAR_SPATIAL
- ANZLIC_METADATA_NAME

- Other NVIS DATA_SET attributes are not provided in this table.
