When does SRTM 1 arc second data come out?
The SRTM 1 Arc-Second Global (30 meters) data set will be released in phases starting September 24, 2014. Users should check the coverage map in EarthExplorer to verify if their area of interest is available. 3 arc-second (approximately 90-meter) medium resolution elevation data are available for global coverage.
Where can I find SRTM / X-SAR data?
The SRTM/X-SAR data may be obtained through the German Aerospace Center (DLR). Coverage Maps indicating the availability of SRTM products are available for download. EarthExplorer can be used to search, preview, and download SRTM Non-Void Filled, SRTM Void Filled, and SRTM 1 Arc-Second Global elevation data.
What is version 3.0 of SRTM global 1?
Version 3.0 SRTM Global 1 arc second product is void-filled using elevation data from Advanced Spaceborne Thermal Emission and Reflection Radiometer ( ASTER) Global Digital Elevation Model 2 ( GDEM2 ), USGS Global Multi-resolution Terrain Elevation Data ( GMTED) 2010, and USGS National Elevation Dataset ( NED ).
What are no data voids in SRTM 90m?
Andy Jarvis and Edward Guevara of the CIAT Agroecosystems Resilience project, Hannes Isaak Reuter (JRC-IES-LMNH) and Andy Nelson (JRC-IES-GEM) have further processed the original DEMs to fill in these no-data voids. This involved the production of vector contours and points and the re-interpolation of these derived contours back into a raster DEM.
How to download 30 Meter SRTM elevation data?

How often does SRTM collect land surface data?
SRTM successfully collected radar data over 80% of the Earth’s land surface between 60° north and 56° south latitude with data points posted every 1 arc-second (approximately 30 meters). The level of processing and the resolution of the data will vary by SRTM data set.
