COLUMBUS, Ohio (AP) – An Ohio State professor is using his skills as a glaciologist to help the relief effort in Nepal. 

The Columbus Dispatch reports (http://bit.ly/1F27JTz ) Ian Howat is used to studying maps of ice-covered terrain to track changes in Antarctica. But he's now teaming up with University of Minnesota researcher Paul Morin to track landscape changes in Nepal following an earthquake that rocked the country last month and killed more than 7,000 people. 

They have helped create software that builds detailed maps from satellite images to show how the landscape in Nepal has changed. They say the maps can give relief crews a sense of what areas are at risk for flooding or landslides.  

Morin says a United Nations relief group has used the maps to identify potentially troubled areas in Nepal.
