USGS: Enhanced topographic data for climate change research

Crater Highlands of Tanzania reveals the difference between 90 meter and 30 meter SRTM data

The United States Geological Survey (USGS) announced that improved global topographic data are now publicly available for most of Asia (India, China, southern Siberia, Japan, Indonesia), Oceania (Australia, New Zealand), and western Pacific Islands.

Elevation data were collected through the Shuttle Radar Topography Mission (SRTM) to deliver precise baseline information that help to better understand the impacts of climate change on specific geographic areas.
