Spatial Navigation Before GPS

"Giant 70-foot concrete arrows that point your way across the country, left behind by a forgotten age of US mail delivery.  Long before the days of radio (and those convenient little smartphone applications), the US Postal service began a cross-country air mail service using army war surplus planes from World War I.  The federal government funded enormous concrete arrows to be built every 10 miles or so along established airmail routes they were each built alongside a 50 foot tall tower with a rotating gas-powered light. These airway beacons are said to have been visible from a distance of 10 miles high."

I love articles like this one where they talk about the collide of different times. This article speaks of huge concrete arrows which were left from 1930's air mail routes. sadly most of the towers that were paired with the arrows have been dismantled but still really cool that these directional arrows from the past can still be found almost 90 years later.

Wow technology has come a long way in just a short amount of time! We would still be using  those stone arrows if it wasn't for the invention of the GPS.

The Age of Megacities

The Age of Megacities | Geography | Scoop.it
The world is a crowded place, with more than 7 billion people on the planet as of 2014. About half of this population lives in urban areas, and ongoing migration into city centers has given rise to the megacity—a metropolitan area with 10 million people or more.

Portraits of people living on a dollar a day

Portraits of people living on a dollar a day | Geography | Scoop.it

"More than a billion people around the world subsist on a dollar a day, or less. The reasons differ but the day-to-day hardship of their lives are very similar. A book by Thomas A Nazario, founder of the International Organisation, documents the circumstances of those living in extreme poverty across the globe, accompanied by photographs from Pulitzer prizewinner Renée C Byer. Living On A Dollar a Day is published by Quantuck Lane."

\I guess it's true what they say; a picture is worth a thousand words. Before even opening this article, you could get a sense from the picture that it wasn't going to be a good one. You can tell by their facial expressions and the environment that surrounds them. Even the colors that are portrayed in the picture send off meaning. The picture is not very bright. It sends off a sad image with all the brown everywhere. However, we do see a little peek of sunlight shining through. Before reading this, one might see this as a good sign from God, or someone watching over these people. Once I opened the article, there were many more pictures describing their lifestyles. You can tell that they don't make much money by the way they live. There was another picture in the article with a dark tint to it, representing a negative atmosphere, including one girl folding her arms and one girl with tears running down her face . There are no pictures were everyone in the images have smiles on their faces.

Hector Alonzo's curator insight, December 15, 2014 7:18 PM

These picture paint a very sad and very real truth. Many of the people in the pictures are caring for children and barely have enough to make it through the day. One woman works long hours for about 50 cents a day and that is horrible, another woman is 40 years old and works at a construction site, which is obviously not the norm. These people, mainly the children, have hope of going to school, but for most of them that is just a dream that will never come true.

Urbanization and the evolution of cities across 10,000 years

"About 10,000 years ago, hunter-gatherers, aided by rudimentary agriculture, moved to semi-permanent villages and never looked back. With further developments came food surpluses, leading to commerce, specialization and, many years later with the Industrial Revolution, the modern city. Vance Kite plots our urban past and how we can expect future cities to adapt to our growing populations."
