Summary
Updates the netCDF layer display or netCDF table view based on the dimension value.
Usage
The input to this tool can be a netCDF raster layer, a netCDF feature layer, a netCDF table view, a mosaic layer, or an image service. If the input is a mosaic layer or an image service layer, it must have a multidimensional information attached to it.
Inputs for this tool can be created using the Make NetCDF Feature Layer, Make NetCDF Raster Layer, Make Mosaic Layer, Make Image Server Layer or Make NetCDF Table View tools.
If a dimension is not specified, its value is set to the first value. The first value is considered the default.
For netCDF layers, auxiliary coordinate variables are not listed in the Dimension Values parameter drop-down list and cannot be set as the value of this parameter in a script.
The By index option matches the input value with the position or index of a dimension value. The index is 0 based, that is, the position starts at 0.
This tool updates the input. In ModelBuilder, an output variable appears that can chain the updated input as input to another tool in the model, but the tool does not produce a new output.
Syntax
SelectByDimension(in_layer_or_table, {dimension_values}, {value_selection_method})| Parameter | Explanation | Data Type |
in_layer_or_table | The input netCDF raster layer, netCDF feature layer, netCDF table view, or mosaic layer. If the input is a mosaic layer, it must be multidimensional. | Raster Layer; Feature Layer; Table View; Mosaic Layer |
dimension_values [[dimension, {value}],...] (Optional) | A set of dimension-value pairs used to specify a slice of a multidimensional variable.
| Value Table |
value_selection_method (Optional) | Specifies the dimension value selection method.
| String |
Derived Output
| Name | Explanation | Data Type |
| output_layer_or_table | The updated input. | Raster Layer; Feature Layer; Table View |
Code sample
