Sep 7, 2017Finding Baltimore’s Mosquito Hotspots with Help from Landsat

High levels of residential abandonment and unchecked vegetation growth in low-income neighborhoods are strong indicators of mosquito prevalence. Higher income neighborhoods are also susceptible to mosquito-borne disease due to the presence of irrigated vegetation, which creates mosquito-friendly habitat.

In western North America, mountain pine beetles infest and ravage thousands of acres of forest lands. Landsat satellites bear witness to the onslaught in a way that neither humans nor most other satellites can.

Thirsting for Equitable Water Distribution, Australia Turns to Landsat
May 25, 2016Thirsting for Equitable Water Distribution, Australia Turns to Landsat

Since record keeping began in 1860, no period has been drier for southeastern Australia than the decade-long Millennium Drought. The lack of rain between 1997 and 2009 led to livestock losses, crop failures, and percentage drops in the Australian GDP.

May 19, 2016Landsat Data Show Rapid Recovery for Some Forests in Santa Cruz Mountains Despite Drought

NASA and the U.S. Geological Survey’s Landsat satellite images over the past three decades showed that the severe drought periods recorded since the 1980s have not slowed rapid tree and shrub growth, especially on steep slopes burned recently by wildfires.
