A number of categories exist in GeoScenic:
Best of BGS images - a selection of very high quality images in a range of sub-categories such as earthquakes and volcanoes, rocks and minerals, fossils and landscapes. The subcategories are representative rather than an attempt to be comprehensive.
Special collections - this set of categories highlights special collections of note. This could be for a region or for certain historical collections from the BGS archives.
Geoscience subjects - a systematic classification of a selection of geological photographs by subject. There is a weighting towards older images, however, over time this will be supplemented with more recent images.
