EarthNow! displays data received from the Landsat 5 and Landsat 7 satellites as they pass over the United States. Landsat satellites have been acquiring images of the Earth's land surface since 1972. More than 2 million Landsat images are in the National Satellite Land Remote Sensing Data Archive.
Hurricanes - Maps and Images

Advances in mapping and geospatial imaging techniques have increased our knowledge and understanding of hurricanes. Scientists can trace the geographic history of hurricanes; measure land changes before and after hurricanes strike; and acquire statistics and data to develop predictive models of future hurricane activity. "Over 100 Years of Land Change for Coastal Louisiana," the U.S. Geological Survey's NationalWetlandsResearchCenter and the Louisiana Coastal Area Land Change Study Group's powerpoint presentation, illustrates multiple examples of these maps and images.
USGS Science Helps Build Safer Communities
USGS
In the United States each year, natural hazards cause hundreds of deaths and cost tens of billions of dollars in disaster aid, disruption of commerce, and destruction of homes and critical infrastructure.
The USGS produced a series of fact sheets to show how USGS science helps mitigate disasters and build resilient communities. This series of fact sheets will educate citizens, emergency managers, and lawmakers on seven natural hazards facing the Nation:
Visit the USGS Natural Hazards Support System for a web-enabled map featuring near-real-time data that provides decision makers and the public with a tool to simultaneously track and analyze numerous natural hazard events.
The NBII Program is administered by the Biological Informatics Program of the U.S. Geological Survey
