This text illustrates the range of environmental geoscience mapping presently carried out around the world. Specialists in several countries have contributed a number of subdisciplinary and thematic topics including volcanic hazards, landslides, dolines, tsunamis, radon potential, medical geology, rainfall erosion, engineering geology, borehole stratigraphy, lake sediment geochemistry, aggregate resources and remote sensing. The collection, analysis and interpretation of data by geologists, geographers and engineers typically involves the presentation of information in map form, which can range from black/white to colour, 2-D to 3-D and paper copy to digital format illustrations. This volume reaffirms the global need for mapping geoscientific data.
