Feature Description

Band operation performs arithmetic operations on bands within a single image dataset, facilitating remote sensing data processing and parameter inversion across industries. You can either select predefined calculation formulas or directly input custom formulas during operations.

For example, comparing NDVI indices of the same area across different years reveals vegetation coverage changes. As shown in the figures, vegetation coverage was higher in 2013 than in 2018.

Supports image datasets only.

SuperMap ImageX Pro 11i(2024) R2 and later versions support this feature.

Parameter Description

Parameter	Description	Type
Source Datasource	Specifies the datasource containing the input image dataset.	Datasource
Source Dataset	Specifies the image dataset for band operation.	DatasetImage
Calculation Method	Provides 29 predefined calculation methods and supports custom formulas.	String
Calculation Formula	When using predefined methods, displays the corresponding uneditable formula. Parameters below require band/value inputs. Example: Selecting NDVI method shows formula "((NIR-Red)/(NIR+Red))" and parameters NIR/Red. Select corresponding bands via dropdown lists. For custom methods: Input formula directly or use formula editor. Represent bands as "Band1, Band2,... Bandn" (e.g., "(Band4 - Band3)/(Band4 + Band3)"). The formula editor provides band lists, common functions, operators, and import/export capabilities. Toolbar buttons demonstrate function usage.	String
Result Datasource	Specifies the output datasource for results.	Datasource
Result Dataset	Specifies the output dataset name.	DatasetGrid

Output

Parameter	Description	Type
Result Dataset	The raster dataset generated from band operation.	DatasetGrid
