General Knowledge
Core S2DRx availability, resolution, AOI, output, and band information.
This article summarizes the shared S2DRx behavior that applies across S2DR3 and S2DR4 access paths.
Temporal Availability
S2DRx can process Sentinel-2 scenes from January 1, 2018 onward. Scene availability follows the Sentinel-2 5-day revisit cadence.
For catalogue checks, use the Copernicus Data Space Browser before selecting a date.
Spatial Resolution
S2DRx outputs are produced at 1 m/px in UTM projection.
Effective resolution can vary by location and terrain type:
- Textures are reconstructed down to 1 m detail.
- Individual objects are reconstructed at roughly 2-3 m scale.
AOI Requirements
You can define an area of interest as either:
- A bounding box.
- A polygon in GeoJSON.
The general S2DRx source gives these technical AOI limits:
| Limit | Value |
|---|---|
| Minimum AOI | 0.4 km2 / 40 ha |
| Maximum AOI | 150 km2 |
Some access paths may have stricter limits. For example, the current Python SDK manual describes a 10x10 km / 100 km2 dev-version AOI limit.
Output Products
S2DRx generates four output products:
| File suffix | Output | Use |
|---|---|---|
_MS.tif | 10-band multispectral image | Analysis-ready multispectral output. |
_TCI.tif | True color RGB image | Visual inspection. |
_NDVI.tif | Pseudo-color NDVI image | Vegetation-focused preview. |
_IRP.tif | Infrared pseudo-color image | Infrared-focused preview. |
Multispectral Band Order
The 10-band multispectral output uses this band order:
| S2DRx band index | Sentinel-2 band | Description |
|---|---|---|
| 1 | B02 | Blue |
| 2 | B03 | Green |
| 3 | B04 | Red |
| 4 | B05 | Vegetation Red Edge 1 |
| 5 | B06 | Vegetation Red Edge 2 |
| 6 | B07 | Vegetation Red Edge 3 |
| 7 | B08 | NIR |
| 8 | B8A | Narrow NIR |
| 9 | B11 | SWIR |
| 10 | B12 | SWIR |
Sentinel-2 bands B01, B09, and B10 are not listed as S2DRx output bands in the general source.
