Count-Find the number of records included in the calculation.Standard deviation-Use the standard deviation classification method on all the input field.Max-Use the maximum value of all the input field values.Min-Use the minimum value of all the input field values.Mode-Use the value with the highest frequency.Median-Calculate the median (middle) of the input field values.Mean-Calculate the mean (average) of the input field values.Sum-Calculate the total of the input field values.
Join-Concatenate (join) the input field values.First-Use the input fields' first value.There are several merge rules you can use to determine how the output field will be populated with values. Input fields are merged or combined into a single output value. Merge rules allow you to specify how values from two or more By default, all fields from the inputs will be included.įields can be added, deleted, renamed, and reordered, and you can change their properties. The attribute fields that will be in the output with the corresponding field properties and source fields. Use the Mosaic To New Raster tool to combine multiple rasters into a new output raster. This tool does not support raster datasets. Use the Append Annotation Feature Classes tool to combine annotation feature classes. This tool does not support annotation feature classes. If feature classes are being merged, the output dataset will be in the coordinate system of the first feature class in the Input Datasets list, unless the Output Coordinate System geoprocessing environment is set. To combine, or planarize, feature geometries, use the Union tool. All features from the input datasets will remain intact in the output dataset, even if the features overlap. This tool will not split or alter the geometries from the input datasets. Learn more about mapping fields in scripts Do not perform standard deviation on a single input because values cannot be divided by zero, so standard deviation is not a valid option for single inputs.You can specify the start and end positions of text fields using the format option.To use a space, ensure that the pointer is at the start of the input box and press the Spacebar once. When using the Join merge rule, you can specify a delimiter such as a space, comma, period, dash, and so on.The available merge rules are first, last, join, sum, mean, median, mode, minimum, maximum, standard deviation, and count.You can manually change the data type at any time to any other valid data type. The default data type of an output field is the same as the data type of the first input field (of that name) it encounters.To change the field order, select a field name and drag it to the new position.To manage the fields in the output dataset and the contents of those fields, use the Field Map parameter. If a table is merged into a feature class, the rows from the input table will have null geometry. If the first input is a feature class, the output will be a feature class, if the first input is a table, the output will be a table. The output type is determined by the first input. Tables and feature classes can be combined in a single output dataset. For example, several point feature classes can be merged, but a line feature class cannot be merged with a polygon feature class. All input feature classes must be of the same geometry type. Use this tool to combine datasets from multiple sources into a new, single output dataset.
