or directly from their FTP site files are named according to latitude and longitude; The GLCF is also a convenient way to browse and download SRTM data, in GeoTIFF format - for more information, see the GLCF SRTM page. They also offer direct FTP access. A very useful server is CGIAR-CSI: SRTM 90m Digital Elevation Data. It also happens to offer

SDTS DEM data format was the USGS attempt at creating a new file format DEM data. NGA Raster Roam. 5 Oct 2018 To access original DEM tiles please refer to MERIT DEM download page. File naming convention: dtm = theme: digital terrain models, twi = variable: SAGA GIS dtm_curvature_merit.dem_m_1km_s0..0cm_2017_v1.0.tif 9 Nov 2017 There are 412 LiDAR point cloud files in LAZ format, four shapefiles .zip format), and four files in GeoTIFF format (.tif) included in this dataset. This data download contains several files used in related tutorials. load raster in an R object called 'DEM' DEM dimensions : the "size" of the file in pixels. Open Layer ‣ Add Raster Layer and browse to the downloaded zip file. In the DEM (Terrain Models) dialog, choose everest_gmted30 as the Input file.
Acquiring and Converting DEM Data in VMG Gasmod Geo indicates that the TIF has a word file, called TWF that stores geographic information about the raster file.

DEM - a raster based (pixel) digital elevation model. The tiles available for download are in Tif format. The tiles available for download are in Tif format. LAS - is a lidar data exchange file which is a standard format for airborne lidar point data. USGS ASCII Digital Elevation Model (*.dem) GeoTiff Graphics File (*.tif) GeoTiff Digital Elevation Model (*.tif) Binary terrain matrix (*.bin) VRML world (*.wrl) Terragen terrain (*.ter) 3DEM can merge multiple DEMs to provide high-resolution overhead maps and 3D projections of large surface areas, limited only by the computer's memory. More about the .tif format: GeoTIFF on Wikipedia; OSGEO TIFF documentation; Geotiffs in R. The raster package in R allows us to both open geotiff files and also directly access .tif tags programmatically. You can quickly view the spatial extent, coordinate reference system and resolution of your raster data. NOTE: not all geotiffs contain tif tags! As a workaround, follow these steps to create a surface from a USGS GeoTIFF DEM file: Click Surfaces menu > Create Surface. In the Create Surface dialog box, select Grid Surface for the Surface Type and click OK. In the Prospector tree, expand the Surface name > Definition collection. Right-click the DEM Files item. Click Add. Recently I was coding some functionality that was dealing with multipage tiff images. Since I hadn’t any multipage pictures on my computer, I thought it shouldn’t be too difficult to find some sample files to test with.. So I started my everday search in google: Multipage tiff example, multipage tiff file sample, multipage tif download etc. ASTER Global Digital Elevation Map Announcement.
