NASA Flights Map Summer Melt of Greenland Ice

Operation IceBridge is flying in Greenland to measure how much ice has melted during the summer. The flights, which began on Aug. 25, 2017, and will go on until Sept. 21, 2017, repeat paths flown this spring and aim to monitor seasonal changes in the elevation of the ice sheet. “We started to mount these

GISCorps Rallies Hurricane Harvey Response

The impacts of Hurricane Harvey are being felt far and wide. As the rain continued to fall, and flood waters rose, an army of citizen-rescuers answered the call. And as governments encouraged citizens to help one another, the non-profit organization made up of mapping experts also answered the call. GISCorps, a program of the Urban

Satellite Navigation Monitors Water Supplies

Water conservation is a growing concern globally, and particularly for farmers in the United States, where decades of irrigating huge fields has depleted vital resources of fresh surface water and groundwater. To help alleviate this problem, a European Space Agency (ESA) spin-off that hopes to help preserve water supplies while guaranteeing crop irrigation is now

Golf Courses Are the Next Drone Mapping Territory

The emerald golfing greens have seen better days. According to the U.S. National Golf Foundation, the number of players has steadily declined from over 30 million in 2005 (pre-recession) to 24.7 million today; 680 US and 158 Canadian courses have closed. “Golf course owners are working smarter to manage resources like water and labor more

Geospatial Science Identifies High-Risk Flooding Areas in Egypt

Researchers from UT Dallas and other universities developed geospatial science methods to help the Egyptian government determine how to avoid flooding in a coastal mountain region. The government wants to develop the area for tourism, but flash flooding and associated hazards have hampered efforts, according to Dr. May Yuan, Ashbel Smith professor of GIS. “We

Historical Records May Underestimate Sea-Level Rise

A new study using NASA satellite data finds that tide gauges—the longest and highest-quality records of historical ocean water levels—may have underestimated the amount of global average sea-level rise that occurred during the 20th century. A research team led by Philip Thompson, associate director of the University of Hawaii Sea Level Center in the School

As Sea Level Rises, Hudson River Wetlands May Expand

In the face of climate change impact and inevitable sea level rise, Cornell and Scenic Hudson scientists studying New York’s Hudson River estuary have forecast new intertidal wetlands, comprising perhaps 33 percent more wetland area by the year 2100. “In other parts of the world, sea level rise has led to net losses of tidal

Dewberry Completes National Hydrography Study for U.S. Geological Survey

Dewberry has completed the National Hydrography Requirements and Benefits Study (HRBS) for the U.S. Geological Survey (USGS). The firm conducted the study—sponsored by USGS and the U.S. Department of Agriculture’s Natural Resources Conservation Service—to establish a baseline understanding of national business uses, needs, and associated benefits for national hydrography data; and to inform the design
