What does the output extent setting do in ArcGIS?

What does the output extent setting do in ArcGIS?

The Output Extent environment setting defines what features or rasters will be processed by a tool. It is useful when you need to process only a portion of a larger dataset.

What are the inputs for overlay layers in ArcGIS?

The Overlay Layers tool requires two inputs: an input layer and an overlay layer. The availability of overlay method options depends on whether the input and overlay layers are points, lines, or areas.

What does intersection of inputs mean in ArcMap?

Intersection of Inputs —The extent in which all input features or rasters overlap (intersect one another). Note that it is possible that none of the features or cells overlap and that a null extent (zero width and height) may result. In such cases, no features or cells will be processed.

What does Union of inputs mean in ArcGIS Pro?

Union of Inputs —The combined extent of all input data. All features or rasters will be processed. Intersection of Inputs —The extent in which all input features or rasters overlap (intersect one another). Note that it is possible that none of the features or cells overlap and that a null extent (zero width and height) may result.

Where does raster data come from in ArcGIS Pro?

If two files contain the same variable with the same dimension values, the slices in the output raster will come from the first multidimensional raster in the list. You can also specify a RasterInfo object as the input inRaster, which will create a new raster dataset on disk.

Is the readonly property true when raster object is created?

Once permanent, the referenced raster dataset cannot return to the temporary state. When a raster object is created by supplying the path to an existing raster on disk, its readOnly property is True by default and its cell values can be read using the [row, column] index notation.

What happens when the referenced raster dataset is temporary?

When the referenced raster dataset is temporary, these properties will be assigned a value of None. The affected properties are catalogPath, compressionType, format, hasRAT, name, and path. Once permanent, the referenced raster dataset cannot return to the temporary state.

How to select layer by attribute in ArcMap?

If an Extent environment is specified, or if a definition query is present on the Input Layer or Table View, only the features or rows within the extent or matching the definition query may be selected. The Get Count tool can be used to determine the number of features or rows selected.

When do you use the output extent setting?

It is useful when you need to process only a portion of a larger dataset. You can think of this setting as a rectangle used to select input features and rasters for processing. Any feature or raster that passes through the rectangle will be processed and written to output. Note that the rectangle is used only to select features, not clip them.

Where does the selection take place in ArcGIS?

The feature layer or table view to which the selection will be applied. The input can be a layer or table view in the ArcMap table of contents, or a layer or table view created in ArcCatalog or in scripts using the Make Feature Layer or Make Table View tools.
