This topic describes the ganos.raster.mosaic_must_same_nodata variable. This variable specifies whether the NoData values in the data source must be the same during the Mosaic operation.

Data type

Boolean

Value

  • true: specifies that the NoData values in the data source must be the same. This is the default value.
  • false: specifies that the NoData values in the data source can be different.
Note PolarDB does not convert the NoData values during the mosaic operation. If you set this parameter to false, the semantics of the pixels may change after the mosaic operation.

Example

set ganos.raster.mosaic_must_same_nodata = false;
