Input polyline features | The input lines to use in the neighborhood operation. For each output cell, a statistic will be calculated for all of the portions of the input polyline features that fall within a circular neighborhood around that cell. The size the circular neighbourhood is defined by the search radius. | Feature Layer |

Field | The field for which the specified statistic will be calculated. It can be any numeric field of the input line features. When Statistics type is set to Length, the Field parameter can be set to NONE. It can be the Shape field if the input features contain z-values. | Field |

Output cell size (Optional) | The cell size of the output raster that will be created. This parameter can be defined by a numeric value or obtained from an existing raster dataset. If the cell size hasn't been explicitly specified as the parameter value, the environment cell size value will be used if specified; otherwise, additional rules will be used to calculate it from the other inputs. See the usage section for more detail. | Analysis Cell Size |

Search radius (Optional) | The search radius that will be used to calculate the statistic within, in map units. The default radius is five times the output cell size. | Double |

Statistics type (Optional) | Specifies the statistic type to be calculated. Statistics are calculated on the value of the specified field for all lines within the neighborhood. The default statistic type is Mean. The available choices for the statistic type are determined by the numeric type of the specified field. If the field is integer, the available statistic choices will be majority, maximum, mean, median, minimum, minority, range, variety, and length. If the field is floating point, only the mean, maximum, minimum, range, and length statistics will be available. - Mean—The average field value in each neighborhood, weighted by the length, will be calculated.The form of the calculation is:
- Mean = (sum of (length * field_value)) / (sum_of_length)
- Majority—The value having the greatest length of line in the neighborhood will be identified.
- Maximum—The largest value in the neighborhood will be identified.
- Median—The median value, weighted by the length, will be calculated.Conceptually, all line segments in the neighborhood are sorted by value and placed end to end in a straight line. The value of the segment at the midpoint of the straight line is the median.
- Minimum—The smallest value in each neighborhood will be identified.
- Minority—The value having the least length of line in the neighborhood will be identified.
- Range—The range of values (maximum–minimum) will be calculated.
- Variety—The number of unique values will be calculated.
- Length—The total line length in the neighborhood will be calculated. If the value of the field is not 1, the lengths are multiplied by the item value before adding them together. This option can be used when the field parameter is set to None.
