National Geochemical Survey of Australia: soil data

Description

A dataset containing the geochemical composition of soil samples covering approx 2/3 of Australia, at a spatial resolution of 1 sample/5000 $km^2$. The original data is published by Geosciences Australia under the Creative Commons CC4 Licence + Attribution (CC-BY-SA-4.0). The provided data set has additional information and some pre-treatment with respect to the one available in the references below. These changes:

Usage

NGSAustralia

Format

An object of class tbl_df (inherits from tbl, data.frame) with 5259 rows and 76 columns.

Details

• Concentrations are all reported as mg/kg, also known as parts per million (ppm). Values below detection limit are reported as minus the detection limit, as standardised in package "compositions".

• The samples were complemented with information about their belonging to one of the major crustal blocks (MCB) of Australia.

• Easting and Northing coordinates were computed using the Lambert conformal conic projection of Australia (earth ellipsoid GRS80; standard parallels: 18S and 36S latitude; central meridian: 134E longitude).
