Evaluation preview. This candidate passed automated QA, but TAK client validation and production promotion are not complete. It is not listed in production TAK product discovery.

Choose a terrain source

The canonical endpoint remains the general default. Alternatives are independent products and may be better suited to a particular terrain model, geography, or analysis. Selecting a source never silently combines it with another source.

Use this source in TAK

ATAK can use this endpoint through its built-in Elevation Tools. Simple DTED Streamer remains optional. The offline ZIP contains this source’s enhanced cells for North Carolina.

Download for offline use

Download the state ZIP and import it with ATAK Import Manager or another TAK client that supports zipped DTED.

Download NC DTED

This package contains this source’s cells only. Source-specific alternatives do not include canonical fallback cells.

Enhanced coverage

Each polygon is a projected 1° × 1° cell. The map shows cells enhanced by this release, not implied baseline or fallback coverage.

Technical comparison

DTED level describes delivered post spacing, not absolute accuracy. Source model, observation method, conversion, terrain, and validation all affect operational suitability.

Common uses and users

These notes describe source characteristics and common applications. They are not a certification or a substitute for mission-specific validation.

USGS SRTM 1 Arc-Second DTED

A near-global, one arc-second radar digital surface model acquired during the February 2000 Shuttle Radar Topography Mission.

Often used for
  • General TAK elevation and terrain visualization
  • Consistent regional and cross-border terrain coverage
  • A broadly compatible canonical state baseline
Common users
  • TAK field teams
  • Incident and mission planners
  • Geospatial integrators
Important limitations
  • A surface model can include vegetation and built features
  • The source observation dates to February 2000
  • One arc-second posting does not imply one arc-second accuracy

USGS 3DEP 1/3 Arc-Second DEM

A continually updated, seamless U.S. bare-earth terrain model at approximately ten-meter native posting.

Often used for
  • Ground slope, drainage, and route analysis
  • Wildland fire, USAR, and incident terrain planning
  • U.S. mapping and visualization that benefits from a bare-earth model
Common users
  • Fire and USAR teams
  • Emergency and route planners
  • Earth scientists and resource managers
Important limitations
  • Coverage is limited to the United States and territories
  • The source is resampled and datum-converted for DTED2 delivery
  • Source-specific endpoints do not fall back to canonical SRTM cells

Coverage comparison

All maps use the same bounds and show each release’s exact enhanced cells. A blank area does not necessarily mean the canonical endpoint lacks fallback terrain.
