Humans have modified the landscape of Planet Earth in many ways. This modification is nothing new—it began as the earliest humans began burning of local grasslands to encourage new growth, tilling the soil for the first agricultural experiments, and building small dams to ensure a water source. Yet today’s changes are more frequent and also larger in area, from the construction of cities, reservoirs, and tunnels, to widespread land use change through the conversion of the natural land cover to cropland, grazing pastures, mining sites, and other uses.

“Balloon View–Nantucket to Boston” map 1885
Aug 27, 2015Cape Cod, 1885

The sandy peninsula of Cape Cod, Massachusetts juts into the Atlantic Ocean with its characteristic crook and twirl in both images: “Balloon View–Nantucket to Boston” made in 1885, and a Landsat 8 satellite image made 129 years later in 2014. Aspirations to rise above the Earth and to record the Earth’s surface from there are a long-standing theme of human culture.

New York City Landsat 8 - 2013
May 27, 2015New York City, 1860

New York City in 1860 was thriving for some of the same reasons the city thrives today. The city’s location was then, and is now, central for the movement of people and freight to and from Europe and elsewhere. Waterways were the primary transportation pathways in 1860. New York’s deep and well-connected port, nearer to the ocean than the ports of other cities on the East coast of the United States, was a huge boon to shipping. The Hudson River connected New York City’s port to a wide gateway westward through the Erie Canal to Lake Erie and beyond. Europe sent and received goods and people across the Atlantic Ocean to New York. Cities on the Great Lakes could enjoy the benefits of shipping to and from Europe, completely by water!

With imagination one can explore and understand how very different life was for people in the United States before the Golden Spike was hammered into the ground in Utah in 1869. That was a much-hailed event that knitted the country together by linking two railroad lines from the eastern and western ends of the continent. Just ten years earlier, when the map at left was made, life was more centered on local transactions. It was hard for families with children to visit friends because travel in this part of the country was slow and arduous, over bumpy dirt roads by horse and wagon. A life involving daily travel for several miles from home each day to work was not feasible. Yet change was in the air even then.

The series of battles that unfolds with these seven maps is considered one of the most important campaigns in naval history; a campaign that ended with the defeat of the powerful Spanish Armada in 1588. Cartographer Robert Adams created these maps for a 1590 book chronicling the famed naval campaign.

Medieval Map of the known world 1450 and the Blue Marble comparison image
Jan 17, 2014Fra Mauro’s Mappamundi

Long before the famous Earthrise photo taken by Apollo astronauts, creating an image or map of the entire known world was a singular human endeavor. Imagine a half a millennium earlier when only those who had traveled could describe distant lands. Imagine watching the hustle and bustle of merchants and sailors returning to the port of Venice. What stories could they tell to paint a portrait of our planet?

Dec 23, 2013Northern San Francisco Bay, 1894

Maps often convey our relationship to the world. In this map of the northern San Francisco Bay and surrounding environs, the early development of the region is recorded in detail. The full and arduous title of this map is “Map showing portions of Alameda and Contra Costa counties, city and county of San Francisco, California, carefully compiled from official and private maps, surveys and data.”

Map of Sicily from 1791 by William Heather

Maps often help us manage our world. In 1797, when cartographic engraver and chart publisher William Heatheri released his New Chart of the Mediterranean Sea, he had the needs of sea merchants foremost in mind.

Geographia: From Antiquity to the Space Age
Nov 21, 2013Geographia: From Antiquity to the Space Age

From the petroglyphs of ancient societies to the stunning views of our planet from space, humans have endeavored to visualize and accurately map our world. As early geographers recorded the experiences from travelers and merchants, they created lists of places and geographic features.
