Pixel Format Conversion
Feature Description
This tool is used to convert the pixel format of a raster dataset to obtain a new raster dataset. It is commonly used in raster data analysis and processing methods such as reclassification and raster algebraic operations. For example, converting the pixel format after reclassification can reduce storage space.
Since the valid value range for NoData is related to the pixel format, the NoData attribute can be modified simultaneously. The value set for NoData must not exceed the value range of the specified pixel format.
Parameter Description
| Parameter Name | Default Value | Parameter Interpretation | Parameter Type |
|---|---|---|---|
| Source Raster RDD | The RasterRDD to be processed. | RasterRDD | |
| Pixel Format | Includes pixel formats such as double, 8-bit integer, unsigned 8-bit integer, short, int, and single. | JavaCellTypeFormat | |
| NoData Value | -999999 | The NoData attribute of the raster dataset, indicating that positions filled with this value in the raster dataset are invalid. Using the default value means not modifying the NoData of the source data. | Double |
