Mapping The Worl'ds Islands - ESRI

Mapping The World’s Islands

Category:Other Tags :

There are over 300,000 islands in the world and most of these are poorly documented or generally unknown. A new United States Geological Survey (USGS) and Esri project has now mapped 340,691 islands of the Earth’s islands and created a GIS dataset that is publicly available.

World Islands GIS Data

As Charles Darwin noted, islands are incredibly diverse and demonstrate how life can exist in the most isolated locations. They also contain many unique cultures and languages, making them socially important. Islands are also all landmasses on our planet. Increasingly, islands are under threat from climate change and sea level rise in particular. The vast majority of islands are small and many are uninhabited. Documenting them might be the only way some of these islands will be remembered in the future. The USGS and Esri effort has created the Global Islands Explorer (GIE), which provides vectorized Global Shoreline Vector (GSV) data available to the public for download. In this database,  every island, including large continental landmasses and very small islands (e.g., Key West), is documented with satellite data, topography, or other raster data as background, and information about the islands, including area, names, coastlines, tectonic plates they belong to, and other information provided.

New Historical Map of Arlington Shows What County Looked Like 100 Years Ago

New Historical Map of Arlington Shows What County Looked Like 100 Years Ago

A new historical map of Arlington allows users to explore what the county looked like 100 years ago.

The digital map depicts a mix of new and old pictures, showing the buildings that were standing in Arlington’s neighborhoods in the 1920s. By clicking pinpoints on a county map, users can check out the homes and businesses that are (or were) located on that site and read caption notes.

“I think that this StoryMap, besides being nifty, allows people to play with it, and also give you a real historical sense of what Arlington used to look like besides these fantastic visions of glamour columns,” said Falls Church News-Press columnist and local historian Charlie Clark, who made the map for the Arlington Historical Society.

A decade after Mars and other chocolate makers vowed to stop rampant deforestation, the problem has gotten worse

ELIZABETHTOWN, Pa. — Mars Inc., maker of M&M’s, Milky Way and other stalwarts of the nation’s Halloween candy bag, vowed in 2009 to switch entirely to sustainable cocoa to combat deforestation, a major contributor to climate change.

But as the United States stocks up for trick-or-treating, Mars and other global chocolate makers are far from meeting that ambitious goal. Over the past decade, deforestation has accelerated in West Africa, the source of two-thirds of the world’s cocoa. By one estimate, the loss of tropical rainforests last year sped up more in Ghana and Ivory Coast than anywhere else in the world.

“Anytime someone bites on a chocolate bar in the United States, a tree is being cut down,” said Eric Agnero, an environmental activist in Abidjan, the economic capital of Ivory Coast. “If we continue like that, in two, three, four years there will be no more forests.”
