raster resampling
Function Description
Assigns the cell values or derived values of the original raster dataset to the cells of the newly generated raster dataset, while also changing the resolution of the raster dataset.
Function Entrances
- Data tab -> Data Processing -> Raster -> Resample.
- Toolbox -> Data Processing -> Raster -> Resample.
Operation Instructions
- Source Dataset: Selects the data source and dataset for the raster that requires resampling. Multiband image data is not supported.
- Source Info: Displays the resolution and number of rows and columns information of the source dataset.
- Parameters
- Sampling Mode: SuperMap provides three raster resampling methods: nearest, bilinear, and cubic. For detailed descriptions of each method, please refer to Introduction to Raster Resampling Methods.
- Resolution: Sets the resolution of the output raster dataset. The default resolution is twice that of the input raster dataset.
- Columns: The number of pixel columns in the output raster dataset. This cannot be modified manually and is controlled by the resolution parameter. The default number of columns is half of that in the input raster dataset.
- Rows: The number of pixel rows in the output raster dataset. This cannot be modified manually and is controlled by the resolution parameter. The default number of rows is half of that in the input raster dataset.
- Result Data: Selects the data source for the result dataset, which defaults to the same as the source data source. Also sets the name of the result dataset. The type of the result dataset is the same as the source dataset.
