What Will SRTM Provide the Public?
Digital Terrain Elevation Data 1 (DTED 1) [Worldwide]
- DTED 1 is a uniform matrix of terrain elevation values at 3 arc-sec / ~90 meter spacing.
- 100X as much data per unit area vs. GTOPO 30 [DTED 0] (30 arc-sec / ~900 meter spacing).
- Vertical Accuracy 2X better current DTED 1 & ??X better than GTOPO 30
- Same Accuracy as DTED 2, but post-spacing of DTED 1
Digital Terrain Elevation Data 2 (DTED 2) [US]
- DTED 2 is a uniform matrix of terrain elevation values at1 arc-sec / ~30 meter spacing.
- 900X as much data per unit area vs. GTOPO 30 [DTED 0] [~30 meter vs. ~900 meter spacing)
Orthorectified Strip Image [Worldwide]
- 30 meter GSD SAR image strips / ascending and descending passes
