SRTM 30m OZT2 Elevation Tiles
This dataset contains SRTM 30-meter resolution elevation data encoded in the OZT2 tile format.
Format
OZT2 is a high-performance elevation tile format:
Compression: ~93% smaller than Terrarium PNG
Prediction: Gradient-based prediction (left neighbor + vertical gradient)
Quantization: Adaptive bit-depth (8/10/12/16-bit per channel)
Codec: Zstd q3 (30× faster encode than Brotli, same decode speed)
Each tile is 256×256 pixels in Web… See the full description on the dataset page: https://huggingface.co/datasets/aliasfox/srtm30m-ozt2-v2.srtm30m-mergedsrtm-global-void-filledThis dataset mirrors the
Shuttle Radar Topography Mission (SRTM) Void Filled digital elevation data from USGS.
It consists of the 15,417 GeoTIFFs available on USGS EarthExplorer in the "SRTM Void Filled" (srtm_v2) dataset.
Each GeoTIFF covers 1x1 degrees.
The data is in WGS84, with a resolution of 1 arc-second/pixel in the United States and 3 arc-seconds/pixel elsewhere.
Coverage is limited to "80% of the Earth's land surface between 60° north and 56° south latitude".
The data is attributed to… See the full description on the dataset page: https://huggingface.co/datasets/allenai/srtm-global-void-filled.srtm30m

SRTM 1 Arc-Second Global
GeoTIFF heightmaps of the Earth's surface labelled according to latitude and longitude.
Mission Description
The Shuttle Radar Topography Mission (SRTM) was flown aboard the space shuttle Endeavour February 11-22, 2000. The National Aeronautics and Space Administration (NASA) and the National Geospatial-Intelligence Agency (NGA) participated in an international project to acquire radar data which were used to create the first near-global set of… See the full description on the dataset page: https://huggingface.co/datasets/novaia/srtm-1-arc-second-global.srtm-3-arc-second-global
