RS_AddBandFromArray (raster: Raster, band: ARRAY[Double])

RS_AddBandFromArray (raster: Raster, band: ARRAY[Double], bandIndex: Integer)

RS_AddBandFromArray (raster: Raster, band: ARRAY[Double], bandIndex: Integer, noDataValue: Double)

​
Parameters

​
raster
Raster
required
The input raster.
​
band
ARRAY[Double]
required
The band index.
​
bandIndex
Integer
The band index value.
​
noDataValue
Double
The NoData value to use for pixels outside the raster extent.

​
Return type

The resulting raster.
RS_AddBandFromArray typecasts the double band values to the given datatype of the raster. This can lead to overflow values if values beyond the range of the raster’s datatype are provided.

​
Example

SELECT RS_AddBandFromArray(raster, RS_MultiplyFactor(RS_BandAsArray(RS_FromGeoTiff(content), 1), 2)) AS raster FROM raster_table
SELECT RS_AddBandFromArray(raster, RS_MultiplyFactor(RS_BandAsArray(RS_FromGeoTiff(content), 1), 2), 1) AS raster FROM raster_table
SELECT RS_AddBandFromArray(raster, RS_MultiplyFactor(RS_BandAsArray(RS_FromGeoTiff(content), 1), 2), 1, -999) AS raster FROM raster_table
