Summary
Retrieves the value of a given pixel using its x, y coordinates.
Usage
This tool is used when you need the pixel value for a geoprocessing model. In ArcMap, ArcScene, or ArcGlobe you can use the Identify tool instead.
Syntax
GetCellValue_management (in_raster, location_point, {band_index})| Parameter | Explanation | Data Type |
in_raster | The raster that you want to query. | Mosaic Dataset; Mosaic Layer; Raster Layer |
location_point | The X and Y coordinates of the pixel location. | Point |
band_index [band_index,...] (Optional) | Specify the bands that you want to query. Leave blank to query all bands in a multiband dataset. | Value Table |
