Major hydrological basins and their sub-basins. This dataset divides the African continent according to its hydrological characteristics. The dataset consists of the following information:- numerical code and name of the major basin (MAJ_BAS and MAJ_NAME); - area of the major basin in square km (MAJ_AREA); - numerical code and name of the sub-basin (SUB_BAS and SUB_NAME); - area of the sub-basin in square km (SUB_AREA); - numerical code of the sub-basin towards which the sub-basin flows (TO_SUBBAS) (the codes -888 and -999 have been assigned respectively to internal sub-basins and to sub-basins draining into the sea)

The dataset supports the Geochemical Atlas of Aotearoa New Zealand (Martin et al. 2023) that highlights the variation in trace element concentrations in near-surface soil materials across Te Ika-a-Māui North Island, Te Waipounamu South Island and Rakiura Stewart Island. Samples were sourced from previous studies, collated from 833 sites from the top 30 cm (maximum) of soil by hand auger from across Aotearoa New Zealand. All samples were dried and sieved to <2 mm, and 15 g aliquots were analysed for a suite of 65 elements (Ag, Al, As, Au, B, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Hg, Ho, In, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, Pd, Pr, Pt, Rb, Re, S, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn and Zr) using inductively coupled plasma mass spectrometry (ICP-MS) on aqua regia digests. The dataset contains Inverse Distance Weighted (IDW) GIS grids of the 65 elements and a polygon GIS feature layer based on the 1:250 000 Geological Map of New Zealand (2020) with mean concentrations of 65 elements for ~230 rock groups across the country. The sample locations have been collapsed to StatisticsNZ meshblock polygons in a point GIS feature layer and a spreadsheet table to protect privacy. These grids and feature layers enable an understanding of the geochemical composition and spatial variation of Aotearoa New Zealand's soils attributable to natural (geogenic) and human (anthropogenic) influences.

Physiographic maps for the CIS and Baltic States (CIS_BS), Mongolia, China and Taiwan Province of China. Between the three regions (China, Mongolia, and CIS_BS countries) DCW boundaries were introduced. There are no DCW boundaries between Russian Federation and the rest of the new countries of the CIS_BS. The original physiographic map of China includes the Chinese border between India and China, which extends beyond the Indian border line, and the South China Sea islands (no physiographic information is present for islands in the South China Sea). The use of these country boundaries does not imply the expression of any opinion whatsoever on the part of FAO concerning the legal or constitutional states of any country, territory, or sea area, or concerning delimitation of frontiers. The Maps visualize the items LANDF, HYPSO, SLOPE that correspond to Landform, Hypsometry and Slope.
