WCS
Web Coverage Service (WCS) (specification), (Wikipedia entry) provides access to original raster data by WCS-clients, e.g. Qgis.
RSDB web interface provides generated WCS layer URLs at “Layer”-tab - “RasterDBs”-layer detail-view - “Applications”-section - “WCS Access”-Button.
RSDB implements WCS 1.0.0.
URL structure: You need to replace LAYER_ID with your chosen RasterDB layer ID.
http://IP:PORT/rasterdb/LAYER_ID/wcs
https://IP:SECURE_PORT/rasterdb/LAYER_ID/wcs

Following some WCS technical details. (A WCS-client, e.g. Qgis, does automatically follow that structure.)
GetCapabilities
Get basic layer information as XML-file.
http://127.0.0.1:8081/rasterdb/my_layer/wcs?SERVICE=WCS&REQUEST=GetCapabilities&VERSION=1.0.0
DescribeCoverage
Get detailed layer information as XML-file.
http://127.0.0.1:8081/rasterdb/my_layer/wcs?SERVICE=WCS&REQUEST=DescribeCoverage&VERSION=1.0.0&COVERAGE=my_layer
GetCoverage
Get raster data as GeoTIFF-file.
http://127.0.0.1:8081/rasterdb/my_layer/wcs?SERVICE=WCS&VERSION=1.0.0&REQUEST=GetCoverage&FORMAT=GeoTIFF&COVERAGE=my_layer&BBOX=xmin,ymin,xmax,ymax&CRS=EPSG:epsg&RESPONSE_CRS=EPSG:epsg&WIDTH=width&HEIGHT=height
Settable parameters:
- BBOX=xmin,ymin,xmax,ymax Bounding box of requested raster in projection coordinates.
- WIDTH=width Width in pixel of requested raster.
- HEIGHT=height Height in pixel of requested raster.
