Label | Explanation | Data Type |

Input Suitability Analysis Layer
| The Suitability Analysis layer that will be used in the analysis. | Feature Layer |

Site Layer ID Field
| A field containing unique values for each record within the Suitability Analysis layer. | Field |

Point Features
| The layer containing point locations to be added as criteria based on spatial relationship to the Suitability Analysis layer. | Feature Layer |

Criteria Type
| Defines the type of spatial relationship to be used as criteria. - Count—A count of points that fall within each Suitability Analysis layer polygon. This is the default.
- Weight—Calculates field-weighted criteria of points that fall within each Suitability Analysis polygon based on the user-selected statistical type.
- Minimal Distance—Adds distance from the closest point to each of the Suitability Analysis layer centroids as criteria.
| String |

Distance Type
(Optional) | Defines how minimal distance is calculated based on method of travel. | String |

Measure Units
(Optional) | Defines the type of distance measuring units to be used when calculating minimal distance. | String |

Site Centers Features
(Optional) | The point layer that will be used as site centers. This point layer will replace default polygon centroids of the Suitability Analysis layer. | Feature Layer |

Site Centers Layer ID Field
(Optional) | A field existing within the Site Centers Features parameter that uniquely identifies each record. | Field |

Weight Field
| Numeric fields that exist within a point layer that can be selected for weighting. | Field |

Statistics Type
(Optional) | The type of statistical operation to be applied to the weighted field. - Sum—Calculates the total of the field values in each point feature.
- Average—Determines the average field value in each point feature.
- Standard Deviation—Calculates the standard deviation of the field values in each point feature.
- Minimum—Determines the smallest field value in each point feature.
- Maximum—Determines the largest field value in each point feature.
| String |

Cutoff
(Optional) | The distance beyond which points will not be considered in the calculation. | Double |
