When was the Royal Geographical Society of London created, and what was its purpose, as noted in the nonfiction book, The Lost City of Z?

The Royal Geographical Society of London was created in 1830. It was instituted to create a map of the world based upon observation rather than imagination. Its mission statement stated that the Society would collect, compile, and print interesting facts and discoveries, have a library of the best books on geography, assemble the best surveying equipment, and help send explorers on their journeys.
