Sources of DEM Data
We are mainly using AWS Open Elevation/Terrain Tiles data by MapZen as the source
https://registry.opendata.aws/terrain-tiles/
We’ve downloaded Global Coverage of this dataset to our server and as needed enhanced it with the best available open source and government datasets
skadiwith extensionhgtin unprojected latlng, 1°x1° tiles
Skadi format tiles are raw elevation data in unprojected WGS84 (EPSG:4326) 1°x1° tiles, used by the Mapzen Elevation lookup service. Essentially they are the SRTMGL1 format tiles but with global coverage and compressed using gzip. See GDAL documentation for more information.
See the SRTM guide for exact format specifications, which are summarized below:
-
The DEM is provided as 16-bit signed integer data in a simple binary raster. There are no header or trailer bytes embedded in the file. The data are stored in row major order (all the data for row 1, followed by all the data for row 2, and so on).
- All elevations are in meters referenced to the WGS84/EGM96 geoid as documented by the National Geospatial Agency.
-
Byte order is Motorola (“big-endian”) standard with the most significant byte first. Since they are signed integers elevations can range from -32767 to 32767 meters, encompassing the range of elevation to be found on the Earth.
-
These data also contain occasional voids from a number of causes such as shadowing, phase unwrapping anomalies, or other radar-specific causes. Voids are flagged with the value -32768.
The underlying data sources are a mix of:
- 3DEP (formerly NED and NED Topobathy) in the United States, 10 meters outside of Alaska, 3 meter in select land and territorial water areas
- ArcticDEM strips of 5 meter mosaics across all of the land north of 60° latitude, including Alaska, Canada, Greenland, Iceland, Norway, Russia, and Sweden
- CDEM (Canadian Digital Elevation Model) in Canada, with variable spatial resolution (from 20-400 meters) depending on the latitude.
- data.gov.uk, 2 meters over most of the United Kingdom
- data.gv.at, 10 meters over Austria
- ETOPO1 for ocean bathymetry, 1 arc-minute resolution globally
- EUDEM in most of Europe at 30 meter resolution, including Albania, Austria, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Kosovo, Latvia, Liechtenstein, Lithuania, Luxembourg, Macedonia, Malta, Montenegro, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, and United Kingdom
- Geoscience Australia’s DEM of Australia, 5 meters around coastal regions in South Australia, Victoria, and Northern Territory
- GMTED globally, coarser resolutions at 7.5″, 15″, and 30″ in land areas
- INEGI‘s continental relief in Mexico
- Kartverket‘s Digital Terrain Model, 10 meters over Norway
- LINZ, 8 meters over New Zealand
- SRTM globally except high latitudes, 30 meters (90 meters nominal quality) in land areas
