Data structure


Field name Type Bytes Label Description
AreaID Text (UTF-8 encoded) 24 AreaID The unique identifier used in WetlandSummary
Name Text (UTF-8 encoded) 11 Name The name of the area used in WetlandSummary, excluding the area type
FullName Text (UTF-8 encoded) 24 Full name The name of the area used in WetlandSummary, including the area type
KML Text (UTF-8 encoded) 111 KML The URL of a simplified KML file depicting this area
TotalArea Double (8 byte floating point) 8 Area (km²) The total area in km²
GRID_CODE Short (2 byte integer) 2 GRID_CODE


The climate zones layer used by WetlandSummary is based on the source layers below, with the following modifications:

  • Name is determined from the GRID_CODE legend in the readme.txt file supplied with the source shapefile
  • Excluded features where GRID_CODE=0
  • Transformed coordinate system of kpngrp.shp from UTM GDA_1994_Lambert_Conformal_Conic to geodetic EPSG:GDA94
  • Fixed 5 invalid geometries
  • Excluded 236 features outside of Queensland
  • Excluded a total of 112 features by filtering
  • Clipped 5 features extending partially beyond the Queensland border (some may be due to minor misalignment at the border)
  • Dissolved 64 source features into 6 climate zones

Koeppen climate classification (base climate related classification datasets)
The grid shows the Koeppen classification indices across Australia in the form of two-dimensional array data. The classification is based on standard 30-year period (1961-1990) rainfall and temperature grids.

The classification was based on mean monthly and annual rainfall, maximum temperature and minimum temperature grids.

For more information see : Stern, H., de Hoedt, G. and Ernst, J. 1999. Objective classification of Australian climates. Aust. Met. Mag. 49 (2000) 87-96.

The base grids were generated using the ANU (Australian National University) 3-D Spline (surface fitting algorithm).
The resolution of the data is 0.025 degrees ( approximately 2.5km) - as part of the 3-D analysis process a 0.025 degree resolution digital elevation model (DEM) was used.  
All input station data underwent a high degree of quality control before analysis, and conform to WMO (World Meteorological Organisation) standards for data quality.

Grid-point indices on the classification grid are as follows:
42  rainforest (monsoonal)
41  savanna
37  rainforest (persistently wet)
36  rainforest (monsoonal)
35  savanna
34  no dry season
33  distinctly dry summer
32  distinctly dry winter
31  moderately dry winter
24  hot (persistently dry)
23  hot (summer drought)
22  hot (winter drought)
21  warm (persistently dry)
15  hot (persistently dry)
14  hot (summer drought)
13  hot (winter drought)
12  warm (persistently dry)
11  warm (summer drought)
Temperate 9  no dry season (hot summer)
8  moderately dry winter (hot summer)
7  distinctly dry (and hot) summer
6  no dry season (warm summer)
5  moderately dry winter (warm summer)
4  distinctly dry (and warm) summer
3  no dry season (mild summer)
2  distinctly dry (and mild) summer
1 no dry season (cool summer)
