サマリー
The Locator class allows you to modify locators and use them for geocoding. Geocoding is the process of transforming a description of a location—such as a pair of coordinates, an address, or a name of a place—to a location on the earth's surface.
The Geocoding module was designed to support locators created with the Create Locator tool. Locators created with legacy tools may have limited functionality, and a number of properties and parameters will not be supported.
説明
A locator is a portable file used to perform geocoding, the process of finding addresses and places on a map. Locators contain a snapshot of the reference data used for geocoding, as well as indexes and local addressing knowledge that help return the best match during the geocoding process.
A locator can be accessed as a service on your portal, such as ArcGIS World Geocoding Service, as a service accessed through an AGS server connection, or as a file on disk.

| プロパティ | 説明 | データ タイプ |
| capabilities (読み取り専用) | Returns the capabilities that are available for a locator that is shared as a service to ArcGIS Enterprise or published as a geocode service to ArcGIS Server. The available capabilities are as follows:
This property is only supported for geocode services. It is not supported for local locators, and an error will be returned if you attempt to access this property for a local locator. | String |
| categories (読み書き) | Controls precision by limiting the categories that can be returned from the locator to a defined set. If you have a multirole locator that supports multiple address types, you can modify this setting to exclude matches to certain types. For example, your locator can support matches to PointAddress level, StreetAddress level, StreetName level, and Postal level. You may want to exclude matches to the Postal level because you consider matches to that level to be too imprecise for your purposes. This setting allows you to control the precision of your geocoding experience. This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | String |
| defaultSuggestCandidates (読み書き) | The number of suggestion candidates that are returned by default from the suggest method. This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | Integer |
| endOffset (読み書き) | The distance in meters to offset the result away from the end (toward the center) of a street feature for display purposes. For more information about how to use the endOffset property, see End offset. This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as a runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | Double |
| intersectionConnectors (読み書き) | The list of intersection connectors, which can be symbols or words, with which to override the default intersection connectors. The list of intersection connectors should be in a quoted comma-separated list, for example, "&","|","//","@". This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as a runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | String |
| matchOutOfRange (読み書き) | Controls whether a match will be returned if the street number searched for is slightly out of range of what is included in the street segment of the data on which the locator was built. To match to a street segment, even if the street number doesn't exist on the line segment in your data but is within a reasonable threshold and is likely to exist, set the property to True. When this property is set to True, the point is placed on the end of the street segment where the address is slightly outside of the house number range. This ensures that you do not miss a potential match because the data is not 100 percent up to date. The matchOutOfRange property only applies to locators that support and return StreetAddress matches. For more information about the matchOutOfRange property, see Match out of range. This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | Boolean |
| maxCandidates (読み書き) | The maximum number of candidates that are returned from the geocode method. If you find that geocoding is taking a long time and you are also getting high-quality matches, ensure that this property is not set too high. Assuming you are getting good results, performance can be improved by generating fewer results and focusing on the top few. This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | Integer |
| maxSuggestCandidates (読み書き) | The maximum number of suggestion results that are returned from the suggest method. If you find that the suggest method has poor performance, it may be because the locator is generating a very large number of suggestion results. Setting this value to a lower number can improve performance. For more information about the maxSuggestCandidates property, see Maximum number of suggest candidates. This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | Integer |
| minCandidateScore (読み書き) | The minimum score that a result must have to be considered a match candidate for the geocode operation. The minimum score for a locator is a value between 0 and 100. Only candidates that meet or exceed the minimum candidate score are returned from the geocode method. This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | Integer |
| minMatchScore (読み書き) | The minimum score that a result of the geocode method must have to be considered a match. The minimum score is a threshold that allows you to control how closely addresses must match their most likely candidate in the reference data to be considered a match. If the potential candidate is below the threshold, the address is not matched to the candidate. The minimum match score for a locator is a value between 0 and 100. A perfect match yields a score of 100. If your workflows require matched addresses with a high level of confidence, set the property to a higher threshold. A higher setting ensures that only the highest-quality matches are returned. To maximize the number of addresses that can be matched, and if you do not mind if some addresses are potentially matched incorrectly, use a lower threshold setting. This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | Integer |
| multilineInputFields (読み取り専用) | The locator fields for multiline geocoding. This property returns a list of arcpy.Field objects for the multiline input fields for the locator. Multiline geocoding table fields can be mapped to a Field object name property when geocoding a table. | Field |
| numberOfThreads (読み書き) | The number of threads that are used for batch geocoding. To make best use of this setting, consider the machine you will be using for geocoding and determine the number of cores available on your machine that you can devote to a geocoding job. Geocoding has the ability to use all of the cores on your machine to complete a geocoding job more quickly. By default, this value is set to a smaller number that should work on any machine regardless of the number of cores available, but it can be configured to use more cores if you know you have them available. It can be set to Auto to detect the cores on your machine and optimize the number of threads used for your machine, or you can choose to devote a specified number of cores to geocoding if you know you need to leave some other resources available for other applications. If you plan to share your locator to ArcGIS Enterprise, it is recommended that you set the property to 4. This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as a runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | Integer |
| partialSubaddressSuggestions (読み書き) | Determines whether subaddresses are returned by the suggest method when only a partial subaddress value is used as input. For more information about how to use the partialSubaddressSuggestions property, see Suggestions for partial subaddresses. This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as a runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | Boolean |
| sideOffset (読み書き) | The distance in meters to offset the result away from and to the side of a street feature for display purposes. For more information about how to use the sideOffset property, see Side offset. This property is read-only for geocode services. To change this property in a published locator, modify the property locally, and publish your locator again. 注意:This property is set as a runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | Double |
| singleLineInputField (読み取り専用) | The locator field for singleline geocoding. This property returns an arcpy.Field object representing the singleline input field for the locator. A singleline geocoding table field can be mapped to this Field object's name property when geocoding a table. | Field |
| spatialReference (読み取り専用) | The spatial reference of the locator. The spatial reference will be the same as the data used to create the locator. 注意:This property is set as a runtime property only. It is not persisted to the locator outside of your current session unless you use the updateLocator method. | String |
| supportedCategories (読み取り専用) | The categories that are supported by the locator. For more information about the supported categories available for custom built locators and ArcGIS StreetMap Premium locators, see Categories to support. | String |
| supportedCountries (読み取り専用) | The countries that are supported by the locator. | String |
| supportedRoles (読み取り専用) | Roles that are supported by the locator. | String |

方法の概要
| 方法 | 説明 |
| geocode (searchText, forStorage, {preferredSearchLocation}, {countryCode}, {categories}, {locationType}, {outFields}, {maxResults}, {minScore}, {outputLanguageCode}, {searchExtent}) |
Takes an address or location as input and returns geocoding result candidates. The result candidates are points that you can display on a map or use as input for other analyses. |
| reverseGeocode (location, forStorage, {featureTypes}, {locationType}, {outputLanguageCode}) |
Takes a PointGeometry object as input and returns the closest address, point of interest, or intersection to that point. The result is a reverse geocoded result that contains information about the match address or location, geometry information including x- and y-coordinates, and additional attributes depending on the Locator used. |
| suggest (searchText, {preferredSearchLocation}, {countryCode}, {categories}, {maxResults}, {searchExtent}) | Generates autocomplete suggestions for incomplete or partial user input. A single suggestion result can be passed to the geocodeWithSuggest method to generate points that you can display on a map or use as input for other analyses. |
| geocodeWithSuggest (suggestResult, forStorage, {preferredSearchLocation}, {countryCode}, {categories}, {locationType}, {outFields}, {maxResults}, {minScore}, {outputLanguageCode}, {searchExtent}) | Takes a single suggest method result as input and returns geocoding result candidates. The result candidates are points that you can display on a map or use as input for other analyses. It is recommended that you pass the same parameters to the geocodeWithSuggest method that you passed when you generated the suggest method result that you are using to achieve consistent results. |
| updateLocator () | Persists changes made to Locator properties during the current Python session to the locator so that the properties are applied for future use. |
方法
geocode (searchText, forStorage, {preferredSearchLocation}, {countryCode}, {categories}, {locationType}, {outFields}, {maxResults}, {minScore}, {outputLanguageCode}, {searchExtent})| パラメーター | 説明 | データ タイプ |
searchText | An address or place-name to find the location of. | String |
forStorage | Specifies whether the results will be persisted. The default value is False, which indicates the results can't be stored, but they can be temporarily displayed on a map, for instance. If you store the results, in a database, for example, set this parameter to True. This parameter only applies to geocoding requests made with ArcGIS World Geocoding Service. For all other locators, the parameter is ignored. 注意:Applications are contractually prohibited from storing the results of geocoding operations using ArcGIS World Geocoding Service unless they make the request by passing the forStorage parameter with a value of True. For a Locator using ArcGIS World Geocoding Service to be valid, you must log in to ArcGIS Online with a valid organizational account. ArcGIS Online service credits are deducted from the organizational account for each geocode transaction. | Boolean |
preferredSearchLocation | An origin point that is used to prefer or boost geocoding candidates based on their proximity to the location. Candidates near the location are prioritized relative to those farther away. | PointGeometry |
countryCode | A comma-delimited string of three-character country codes that limits geocoding results to the set of specified countries, which will improve the accuracy of geocoding in most cases. When no country is specified, geocoding with suggestions is performed against all countries supported by the locator. If you are using ArcGIS World Geocoding Service, refer to this list of supported countries. | String |
categories | A comma-separated list of categories that limits the types of places the locator searches, thus eliminating false positive matches and potentially speeding up the search process. See the REST API web help for details about category filtering. | String |
locationType | Specifies the preferred output location for PointAddress matches. If the preferred location does not exist in the data, the default location will be returned instead. For geocode results with Addr_type=PointAddress, the x,y attribute values describe the coordinates of the address along the street, while the DisplayX and DisplayY values describe the rooftop, or building centroid, coordinates. This argument only affects the geometry, not the attribute values.
| String |
outFields | The list of fields to be returned as part of the attributes in the result. This parameter supports a single field name or a comma-delimited string of field names (without spaces). To return the default output fields, outFields does not need to be passed. Use an asterisk ("*") to return all available output fields with the result. The output fields are described in What's included in the geocoded results. | String |
maxResults | The maximum number of locations, up to the maximum number allowed by the Locator. If not specified, all matching candidates up to the maximum specified in the Locator properties are returned. | Integer |
minScore | Limits the candidates that are returned to those with a score above the value set for this property. The value should be between 0 and 100. | Integer |
outputLanguageCode | The language in which the geocode results are returned. Since addresses and places in many countries are available in more than one language, this ensures that results are returned in the expected language. If you are using ArcGIS World Geocoding Service, refer to the list of supported countries to see what language codes are supported for those countries. | String |
searchExtent | An extent that limits the area to be searched. All results that are returned outside of the specified extent are excluded. | Extent |
| データ タイプ | 説明 |
| List | The output of the geocode operation is a list of dictionary objects. Each dictionary object represents a single geocoding result. Each geocoding result contains information about the match address or location, geometry information including x- and y-coordinates, and additional attributes depending on the Locator used and the outFields specified. |
