Climate Station Proximity (20m grid)
dataset:
CLIMPROX20
Thiessen polygons were generated for climate stations point locations for Victoria, and attributed with the station ID. Polygons were rasterised based on VICMAP_ELEVATION_DTM_20M. Site information was obtained from the Queensland Department Natural Resources SILO website (http://www.nrw.qld.gov.au/silo/ppd).

- Supplemental Information
- Relationship to other Datasets: The layer is derived using ESOCLIM and DEM250. For a given area one can expect high correlations between RAIN<month> and DEM250 Current Design Issues: The layer is a raster dataset, ie. a GRID. To reduce disk storage it is stored as an integer value grid with precision maintained to two decimal places using: value = mm/annum * 100. Future Design Issues: As DEM250 is replaced by a higher resolution DEM it may be appropriate to re-calculate the rainfall estimates. For specific areas it will be appropriate to use additional rainfall data to update the ESOCLIM surfaces and generate higher resolution rainfall estimates. Layer design should be revised at that time. Related Documents: None ESOCLIM documentation (CLIM_GRD.DOC) ANUCLIM Users Guide

Quality
- Missing Data
- Complete for the state. Complete for all Victorian Catchment Management Authority (CMA's) areas.
- Attribute Quality
- Normally claimed to be within 5% of the actual value. This is based on a generalised cross-validation algorithm which carries out the original interpolation without each point in turn, and compares the interpolated value at that point with the observed value.
- Positional Accuracy
- Precision: 10-100m Determination: Based on the input map scale for the data underpinning VICMAP_ELEVATION_DTM_20M.
Lineage
- Description
- The polygon dataset is generated from points via ArcGIS Toolbox Thiessen Polygon function. The polygon coverage was converted to grid via ArcInfo workstation, based on DEM25
