dt1 & dt2


dt1,dt2 & dt3


Worldwide DTED Digital Terrain Elevation Data

dt1, dt2 and dt3 is available for purchase as bulk download for the world or a region

or use our API to request an area of interest for your mission area.  1 Degree DTED Tile Index (dt1,dt2,dt3) GeoPackage Vector Features to review Coverage  37mb

Coming soon you will be able to use the new version of Offline Map Data Generator iOS/Android or Windows

The app will use the API and request an users area of interest and within minutes deliver a zip file ready to load into ATAK or WINTAK or other apps.

We are offering a special promotion that combines DTED data and pre-staged basemap data  — CONTACT US for price list for this and special link to purchase both at the discounted rate

Tech Maven Geospatial are subject matter experts in offline mapping and delivering data for DDIL Environments (Denied, Disrupted, Intermittent, and Limited (bandwidth)

We have a large capacity for producing data and we have ready-to-go data and API’s.

We build specialized tools and software for working with map tiles and serving map tiles

Sources of DEM Data

We are mainly using AWS Open Elevation/Terrain Tiles data by MapZen as the source

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

  • skadi with extension hgt in 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.
  •, 2 meters over most of the United Kingdom
  •, 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
