High Resolution Elevation data for South Africa
The FUSEDEM 5m elevation model is purpose-built for infrastructure, road, water, and land development projects. Developed by fusing SUDEM5 with high-resolution DEMSA2 Level 3 patches, then downsampled to 5m, FUSEDEM offers a unique blend of coverage, consistency, and accuracy; optimized for engineering-grade use.
FUSEDEM delivers the best of both worlds, the nationwide consistency of SUDEM with the engineering-grade detail of DEMSA2 L3. Served via our API, it plugs straight into your design environment with zero conversion or setup effort.
“Built for seamless API integration, FUSEDEM gives you the reach of SUDEM with the precision of DEMSA2, all in one streamlined API-ready dataset.”

| Dataset / Product | Resolution | Accuracy (Vertical / Horizontal / Error Stats) | Coverage / Type / Access |
| DEMSA2 (GeoSmart) | 2 m | ~0.5 m vertical, <1 m horizontal | South Africa · DSM (L1/L2), DTM (L3) · TIF/IMG/GDB |
| FUSEDEM (GeoSmart) | 5 m | 0.5–1.7 m vertical, 1–2 m horizontal | South Africa · DTM-like (fusion of SUDEM+ & DEMSA2 L3) · API |
| SUDEM (GeoSmart) | 5 m | ~3 m vertical, 1–3 m horizontal | South Africa · DEM · Older-model TIF/IMG/GDB |
| SUDEM+ (GeoSmart) | 5 m | ~1.5 m vertical, 1–3 m horizontal | South Africa · DEM (improved SUDEM) · TIF/API |
| SRTM / NASADEM (Open Source) | ~30 m | ~6–10 m RMSE typical (±10–16 m LE90), ~30 m horiz. | Global (60°N–56°S) · DSM-like radar DEM · Free TIF |
| Bing Maps Elevation API (Open Source) | US: ~10 m; Global: ~90 m (remote ~900 m) | Source-dependent: US (NED ±2–3 m), Global (SRTM ±10–16 m) | Global · Mixed DSM/DTM (SRTM/NED) · API (deprecated 2028) |
Elevation Model Accuracy Comparison
IMPORTANT:
- SRTM and NASADEM are global, open-source Digital Elevation Models (DEMs) derived from radar. Both represent surface elevations that include terrain and features (i.e., DSM-like). NASADEM is an enhanced version of SRTM, with improved void filling and vertical accuracy.
- DEMSA2 L1 and L2 are provided as a digital surface models (DSM), not a digital terrain model (DTM). In other words, DEMSA2 L1 and L2 consists of the bare earth elevation and the heights of objects (e.g. trees, buildings) on the earth’s surface.
- DEMSA2 L3 is a digital terrain model (DTM), representing ground-only elevation, derived from DEMSA2 L2 surface model with buildings and vegetation removed.
- SUDEM is a national digital elevation model (DEM) of South Africa, closely representing terrain surface (DTM-like)
