Appendix J: Worked Example
- Here is an example of a vegetation description record altered to conform with version 6.0 of the Australian Vegetation Attributes.
- The database keys are shown for illustrative purposes only. Their values should not be copied into the database.
- The example uses a vegetation type with the SOURCE_CODE "51" supplied by the Queensland Herbarium to the NVIS (2000) database.
- This type occurs in about 50 map units, of which 3 are shown, highlighted, below.
- The example illustrates the resolution of mosaics into the preferred format. In this case, all of the relevant data was supplied in the field SOURCE_CODE, but in a sub-optimal format.
- This has been split into the unique SOURCE_CODE_COMPONENT and the corresponding content in VEG_DESC_POSITION and VEG_DESC_PROPORTION.
- The fields marked with asterisks will be deleted from the final NVIS database once the mosaics have been resolved into their component vegetation descriptions. These fields are described in Appendix I.
- I.e. the mosaics are "resolved" when each SOURCE_CODE = Each SOURCE_CODE_COMPONENT.

- The following table shows the description of source code 51 with the "+/-" terminology based on the attribute TAXON_DATA_ALWAYS_THERE.
- The "+/-" terminology for GROWTH_FORM_ALWAYS_THERE has not been shown, since we anticipate that it would be used sparingly.
- Where the mosaic is resolved, the VEG_DESCRIPTION AND MAP_UNIT tables become relatively simple and the number of records is dramatically reduced.
