Since the time GTOPO30 was completed, higher quality elevation data has become available, due to new data sources. The U.S. Geological Survey (USGS) and the U.S. National Geospatial-Intelligence Agency (NGA) have compiled an enhanced global elevation model named the Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) that replaces GTOPO30 dataset.

* U.S. Releases Enhanced Shuttle Land Elevation Data
* The Digital Elevation Model (DEM) data archive
Starting from the GMTED2010 data files at 15 arc-second spatial resolution, aggregated into one file by the team assembling the datasets needed for the TROPOMI data processing, the TEMIS team has compiled the elevation data in more practical data files at selected resolutions. These files provide the average elevation of the grid cell, the standard deviation of this averaging, as well as the minimum and maximum elevation values within the grid cell.
