How to download srtm files

The files linked here are version of an effort by the folks at CIAT-CSI to scrub, polish, and remove gaps in the raw SRTM data released by NASA. The SRTM grid originally comes from this KMZ file for browsing the same data in Google Earth. Any download policies of the respective mirrors apply. The NASA Shuttle Radar Topographic Mission (SRTM) has provided digital elevation data (DEMs) for over 80% of the globe. This data is currently distributed free of charge by USGS and is available for download from the National Map Seamless Data Distribution System, or the USGS FTP site. File size is approximately 25 MB for 1-arc-second data files and approximately 3 MB for 3-arc-second data files. EarthExplorer can be used to search, preview, and download Shuttle Radar Topography Mission (SRTM) 1 Arc-Second Global data. The SRTM collections are .

The Shuttle Radar Topography Mission (SRTM) (Wikipedia article) is a NASA mission conducted in to obtain elevation data for most of the bltadwin.ru is the current dataset of choice for digital elevation model (DEM) data since it has a fairly high resolution (1 arc-second, or around 25 meters), has near-global coverage (from 56°S to 60°N), and is in the public domain. Our online converter of SRTM HGT format to TIFF / BigTIFF / GeoTIFF .tif) format (SRTM to TIF) is fast and easy to use tool for both individual and batch conversions. Converter also supports more than 90 others vector and rasters GIS/CAD formats and more than 3 coordinate reference systems. If the coordinate system of your input data is. Using SRTM data: Map library can graphically open and merge tiles on the fly ; Open and merge DEMs on the File, Open submenu.; Do automatic filling of the voids; pick this, and set the maximum size void to fill, on the Import/Export tab of the Options bltadwin.ru will remove smaller holes, but not the large "Swiss cheese" DEMs in many mountainous regions.

As described in a previous post it’s possible to download the 90m SRTM using the getData () function as follows: srtm SRTM', lon=16, lat=48) Select Dataset: The first argument specifies the dataset. ‘SRTM’ returns the SRTM 90 elevation data. Specify Lon: The second argument specifies the lon of the SRTM tile. EarthExplorer can be used to search, preview, and download SRTM Non-Void Filled, SRTM Void Filled, and SRTM 1 Arc-Second Global elevation data. The collections are located under the Digital Elevation category below the SRTM sub-category. Now you have a good choice of different types of DEM (including both SRTM) which can be downloaded and stored as a separate file in the images's folder. Very convenient. Cite.
