Big Map Blog
Think of the Big Map Blog as an anthology of fascinating maps. According to the blog curator, more than two thirds of the maps come from the Perry-Castañeda Map Collection, Rumsey Map Collection, Library of Congress, and USGS Earth Explorer. The images are available elsewhere, but like any anthology, having them on one site makes access easier.
J Andriveau-Goujon’s Comparative Mountain Heights (1850)
Images are diverse:
- J Andriveau-Goujon’s Comparative Mountain Heights (1850), produced before the Great Trigonometric Survey of British India established the first published height of Everest,
- Marshall Islands “Stick Maps” (1920s) used by traditional Pacific island navigators,
- T Ditterline’s map of Gettysburg on July 1st, 2nd, and 3rd (1863), and
- the Central Intelligence Agency's topographic map of the West Bank and vicinity (1984)
Users with plenty of time can browse the complete collection, more than 600 maps, or, more efficiently, browse by category: birdseyes, topographic, non-western, railroad, military, thematic maps and more. A pull-down menu offers 27 categories. Users can keyword search, but the results can be iffy. For example, a search for “bicycle” produces three maps, two showing bicycle routes and a third of 1598 Ireland, but no “bike” routes. By the way, adding “route” will display all maps with the “route” in the title. In the end, this is a small whinge.
Big Map Blog also links to other sites, the four sites named above, and more with maps of historical interest. Strange Maps and Radical Cartography present some unusual maps. Making Maps: DIY Cartography highlights resources that supplement the book Making Maps by John Krygier and Denis Wood and helps students make better maps.
