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 DEM250.
