WMS This web service provides access to the Geoscience Australia (GA) ISOTOPE database containing compiled age and isotopic data from a range of published and unpublished (GA and non-GA) sources. The web service includes point layers (WFS, WMS, WMTS) with age and isotopic attribute information from the ISOTOPE database, and raster layers (WMS, WMTS, WCS) comprising the Isotopic Atlas grids which are interpolations of the point located age and isotope data in the ISOTOPE database. This internal database is only publicly accessible through the web service. The data structure currently supports summary ages (e.g., U-Pb and Ar/Ar) as well as extended system-specific tables for Sm-Nd, Pb-Pb, Lu-Hf and O- isotopes. ISOTOPE and the data holdings were initially developed as part of the Exploring for the Future (EFTF) program.
