All features from both the input feature class and the target feature class will remain intact after the append, even if the features overlap. This tool will not planarize features when they are added to the target dataset.

Fields can also be mapped using Python scripts.

To access the Slice Text button, hover over a text field in the input fields list then specify the start and end character positions.

Use the Slice Text button on text source fields to choose which characters from an input value will be extracted to the target field.

Standard Deviation is not a valid option for single input values.

Click the start of the Delimiter text box to add the delimiter characters.

When using the Concatenate action, you can specify a delimiter such as a comma or other characters.

The available actions are First, Last, Concatenate, Sum, Mean, Median, Mode, Minimum, Maximum, Standard Deviation, and Count.

Use an action to determine how the values from one or multiple fields from the input dataset will be mapped to a single field from the target dataset.

Use the Field Map parameter to map or match the fields from the input datasets to fields in the target dataset.

The Field Map parameter can only be used if Use the Field Map to reconcile schema differences is specified for the Schema Type parameter. Use the Field Map parameter to control how the attribute information from the input dataset fields is transferred to the target dataset. For example, several tables can be appended to an existing table, or several rasters can be appended to an existing raster dataset, but a line feature class cannot be appended to a point feature class. This tool can append point, line, or polygon feature classes, tables, rasters, annotation feature classes, or dimension feature classes to an existing dataset of the same type. The output cell size is calculated by taking the average of the projected distances from the center point to its four adjacent points.Use this tool to add new features or other data from multiple datasets to an existing dataset. The center of the original extent is projected to the output coordinate system. The output cell size is calculated based on the ratios of the areas of the projected extent to the original extent. The same number of square cells are preserved in the projected extent as are in the original extent. When projecting from GCS to PCS, or PCS to GCS, the output cell size is calculated based on the average of the ratios of the four sides and the two diagonals of the projected extent to the original extent.

When transforming from one geographic coordinate system (GCS) to another GCS, angular units are converted. When projecting from one projected coordinate system (PCS) to another PCS, linear units are converted by the relevant factor. Units are converted based on the types of coordinate systems involved. The output cell size is calculated by taking the average of the projected distances from the center point to its four adjacent points.Ī = cellsizeprojectionmethod_option Center of extent-The center of the original extent is projected to the output coordinate system.Preserve resolution-The same number of square cells are preserved in the projected extent as are in the original extent.Convert units-Units are converted based on the types of coordinate systems involved.It is recommended that you specify the cell size projection method appropriate for the analysis.

The default Convert units option is equivalent to the technique used in previous releases.Learn more about How the Cell Size Projection Method setting works Usage notes Tools that honor the Cell Size Projection Method environment will use the specified method for calculating the output raster cell size when datasets are projected during analysis.
