A 5-mile island built to save Lagos’s economy has a worrying design flaw

The key to understanding Lagos, Africa’s most populous city, is in the water.

From the sea Lagos rose, from humble port city to economic and political powerhouse and sprawling home to around 22 million. It’s the water that the city is named for—“Lagos,” from the Portuguese word for lakes. Many of the poor, who make up 70% of the city’s population, live in floating shanty slums in the city’s lagoons.

120 LANDSAT DATA APPLICATION

The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. On July 23, 1972 the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat. The most recent, Landsat 8, was launched on February 11, 2013. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, urban and regional planning, surveillance and education, and can be viewed through the USGS ‘EarthExplorer’ website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from 15 to 60 meters; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide (or 100 nautical miles long and 100 nautical miles wide, or 185 kilometers long and 185 kilometers wide).

GIS QUESTION

What Makes A Good GIS Question?

Good geographic information system (GIS) questions are not easily created. They can be mysterious to some, unknown to others and cause others to scratch their heads in curiosity. Since most questions posed to GIS are relatively simple – where is this? Most users have their answers satisfied and move on. But a much smaller number of people seek answers to more complex questions that are not immediately available – or even understood.
