Environmental Covariate Rasters for a Subset of the Lower Hunter Valley, NSW
Description
A suite of GeoTIFF rasters representing environmental covariates for a subset of the Lower Hunter Valley in New South Wales, Australia. These covariates are used in digital soil mapping and terrain analysis.
Format
The dataset consists of multiple raster layers (GeoTIFF format) located in the inst/extdata/ directory of the package, each with a spatial resolution of 25 m × 25 m and a CRS of WGS 84 UTM Zone 56.
Available files are prefixed with hunterCovariates_sub_ and include:
hunterCovariates_sub_Terrain_Ruggedness_Index.tifTopographic ruggedness index (TRI).
hunterCovariates_sub_AACN.tifElevation above channel network base level.
hunterCovariates_sub_Landsat_Band1.tifLandsat 7 ETM+ Band 1 reflectance (0.45–0.52 µm).
hunterCovariates_sub_Elevation.tifElevation in meters above sea level, derived from a DEM.
hunterCovariates_sub_Hillshading.tifHillshade raster generated from the DEM using a fixed sun angle.
hunterCovariates_sub_Light_insolation.tifPotential solar radiation calculated over a calendar year at 5-day intervals.
hunterCovariates_sub_Mid_Slope_Position.tifSlope position classification for crest/valley context.
hunterCovariates_sub_MRVBF.tifMulti-resolution valley bottom flatness index.
hunterCovariates_sub_NDVI.tifNormalized Difference Vegetation Index based on Landsat 7.
hunterCovariates_sub_TWI.tifTopographic Wetness Index (TWI).
hunterCovariates_sub_Slope.tifSlope angle in degrees.
Details
The subset area corresponds to the Hunter Wine Country Private Irrigation District (HWCPID) in the Lower Hunter Valley (approx. 32.83°S, 151.35°E), located ~140 km north of Sydney. The HWCPID covers around 220 km² and supports viticulture and dryland grazing under a temperate, humid climate with ~750 mm annual rainfall.
These covariates are used in spatial prediction tasks, terrain classification, and training examples in digital soil mapping.
