RasterStack of selected environmental covariates for a small area of the Edgeroi district in NSW, Australia.
edgeGrids is an 87 row, 117 column, 5 layer
RasterStack of selected environmental covariates from a small area in the Edgeroi district NSW, Australia. The grids have a pixel resolution of 90m x 90m. It contains the following layers:
numeric; gamma radiometric data
numeric; topographic variable of bare earth ground elevation. Derived from digital elevation model
numeric; panchromatic band of the Landsat 7 satelite
numeric; Slope gradient of the land surface. Derived from digital elevation model
numeric; topographic wetness index. Secondary derivative of the digital elevation model
The Edgeroi District, NSW is an intensive cropping area upon the fertile alluvial Namoi River plain. The District has been the subject of many soil invetigations, namely McGarry et al. (1989) whom describe an extensive soil data set collected from the area. More recently, digital soil mapping studies of the area have been conducted, for example, Malone et al. (2009).
The raw spatial data that contributed to the creation of
edgeGrids were sourced from publically accessable repositories hosted by various Australian Government and international agencies including CSIRO (for the DEM), Geosciences Australia (for the radiometric data) and NASA (for the Landsat 7 ETM+ data). The projection for the
RasterStack is WGS 84 Zone 55.
