########## docs/api/sql/Raster-Operators/RS_AsRaster.md: ########## @@ -26,7 +26,7 @@ Introduction: `RS_AsRaster` converts a vector geometry into a raster dataset by * `pixelType`: Defines data type of the output raster. This can be one of the following, D (double), F (float), I (integer), S (short), US (unsigned short) or B (byte). * `allTouched` (Since: `v1.7.1`): Decides the pixel selection criteria. If set to `true`, the function selects all pixels touched by the geometry, else, selects only pixels whose centroids intersect the geometry. Defaults to `false`. * `value`: The value to be used for assigning pixels covered by the geometry. Defaults to using `1.0` if not provided. -* `noDataValue`: Used for assigning the no data value of the resultant raster. Defaults to `null` if not provided. +* `noDataValue`: Used for assigning the no data value of the resultant raster; pixels not covered by the geometry are set to this value. Defaults to `null` if not provided, in which case uncovered pixels are `0` and the raster has no no data value. Review Comment: I'm not sure what the project's position on matching behavior should be. I guess my opinion (without regard to prior art) is that the default should be the NDV of `ref` and if `ref` has no NDV we should error or return null. But of course this is a breaking change. The current behavior of setting the pixel to 0 but not setting the NDV to match is not great. But maybe it is the least bad solution. -- This is an automated message from the Apache Git Service.
