For the first time ever, measurements from NASA Earth-observing research satellites are being used to help combat a potential outbreak of life-threatening cholera. Humanitarian teams in Yemen are targeting areas identified by a NASA-supported project that precisely forecasts high-risk regions based on environmental conditions observed from space.

Image from GIS Geography. 100 Earth Shattering Uses and Applications of Remote Sensing.

GIS Geography published a list of 100 uses and applications of remote sensing, where data from NASA’s Terra satellite appeared in over 10%.

Listed below are some examples of Terra data uses that made the list (numbered by their original order in the article from GIS Geography):

13. Identifying forest stands and tallying their area to estimate forest supplies (MODIS)

26. Fighting wildfires by planning firefighter dispatch (MODIS)

27. Monitoring air quality in the lower atmosphere (MOPITT)

38. Keeping tabs on the shift from rural to urban growth (MODIS)

39. Quantifying crop conditions with Normalized Difference Vegetation Index (NDVI from MODIS)

59. Monitoring active volcanoes using thermal remote sensing (ASTER, MISR, and MODIS)

66. Looking at the Earth as an art masterpiece NASA’s Earth as Art | NASA Visible Earth

70. Comparing climatic factors from past to present (MODIS, CERES, MOPITT)

75. Studying geology of the Earth’s surface (ASTER, MISR, MODIS)

77. Measuring albedo for Earth’s radiation budget (CERES)

83. Delineating watersheds using DEMs for hydrologists (ASTER)

85. Using a least-cost analysis and vegetation to understand wildebeest migration (NDVI from MODIS)

Shrinking Shoreline of the Salton Sea

Salton Sea as seen by ASTER

NASA Earth Observatory images by Jesse Allen, using ASTER data from NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team, and Landsat data from the U.S. Geological Survey.

Fed primarily from agricultural irrigation runoff, the Salton Sea in southern California’s Sonoran Desert has dropped by 8 feet since 1984. While drought in California has contributed to the receding shoreline, water conservation efforts also play a role. The sea may be reduced to two small pools by the 2030s. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured this image showing the exposed Deltas along its southern shore.

A Fault Runs Through It

Aster Image of Patrick Island

NASA Earth Observatory image by Jesse Allen, using data from NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team.

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite, captured the image of Prince Patrick Island in Northern Canada. The image was featured on NASA’s Earth Observatory, showing the dendritic drainage pattern of interlocking steam and river channels, as well as, strike-slip faults, evidence of Prince Patrick’s seismic history. Prince Patrick Island is usually surrounded in sea ice, while temperatures average -33 degrees Celcius in January. This cold, inhospitable terrain is not a frequent travel destination, but through satellite imagery, much can be learned about this mostly uninhabited part of our planet.
