Popular collection categories are data visualization, celestial, antique atlas, globe, school geography, maritime chart, state atlas, county atlas, city atlas, pocket, wall & case, children's, and manuscript maps. NEW: Random Browse the collection (desktop and tablet only). The online map collection is both a searchable database and a way to make your own journeys into spatial representations of the past. The collection includes rare 16th through 21st century maps of America, North America, South America, Europe, Asia, Africa, Pacific, Arctic, Antarctic, and the World. The historical map collection has over 110,000 maps and related images online. The physical map collection is housed in the David Rumsey Map Center at the Stanford University Library. The David Rumsey Map Collection Database has many viewers and the Blog has numerous categories. The updated world Köppen-Geiger climate map is freely available electronically in the Supplementary Material Section.View High Resolution Interactive Globe View All Interactive Globes Globally the most common climate type by land area is BWh (14.2%, Hot desert) followed by Aw (11.5%, Tropical savannah). We discuss some problems in dealing with sites that are not uniquely classified into one climate type by the Köppen-Geiger system and assess the outcomes on a continent by continent basis. Climatic variables used in the Köppen-Geiger system were calculated at each station and interpolated between stations using a two-dimensional (latitude and longitude) thin-plate spline with tension onto a 0.1°×0.1° grid for each continent. Here we have produced a new global map of climate using the Köppen-Geiger system based on a large global data set of long-term monthly precipitation and temperature station time series.

It is also still in regular use by researchers across a range of disciplines as a basis for climatic regionalisation of variables and for assessing the output of global climate models.

It is widely used in teaching school and undergraduate courses on climate. Although now over 100 years old, the classification of climate originally formulated by Wladimir Köppen and modified by his collaborators and successors, is still in widespread use.
