Louisiana is Losing Ground

Using historical aerial imagery from NASA and USGS, ProPublica has put together an impressive interactive mapped visualization of the effect of climate change and oil & gas exploration on the state of Louisiana.

Southern Louisiana is losing 16 square miles a year to the Gulf of Mexico. At the heart of ProPublica's map, Losing Ground, is a series of timeline visualizations of historical aerial imagery. These timelines allow you to observe the loss of land in Louisiana by comparing present day aerial imagery with aerial imagery going back to the 1930's.

For example, here is the area of Venice and West Bay as it looked in 1932:

Here's how the same area looks today:

Accompanying the aerial imagery are a series of interviews of people living and working in the affected areas. These interviews are supported by audio files and photos. In combination the audio, photos, interviews and aerial imagery of Louisiana's land loss provide a powerful report into this ongoing environmental disaster.
