概要
入力テキストまたはテキスト ファイルを解析し、位置をポイント フィーチャクラスに抽出します。
入力テキストがファイル パスの場合、識別されるファイルが開かれ、そのコンテンツが解析されます。入力テキストが非構造化情報 (電子メール メッセージなど) または半構造化テキスト (旅行フォームなど) の場合、入力テキストそのものが解析されます。このツールは、テキストまたはファイルのコンテンツにある位置を抽出して、生成されるポイントをフィーチャクラスに追加します。
このツールは、次のようにテキストを解析して処理します。
- テキストのコンテンツで指定された空間座標を認識して、それらの位置を表すポイントを作成します。認識される座標形式は、度 (10進)、度分 (10進)、度分秒、ユニバーサル横メルカトル図法、MGRS (Military Grid Reference System) です。
- カスタム位置情報ファイルで定義されているテキストのコンテンツで指定された地名を認識して、それらの位置を表すポイントを作成します。カスタム位置情報ファイルは、地名をその位置を表す空間座標に関連付けます。
- 対象のテキストを認識し、指定されたテキストからこの情報を抽出して、出力フィーチャクラスの属性テーブル内のフィールドに記録します。
使用法
The parameter default values are designed to optimize the identification of coordinates and dates. Default values can be modified for each parameter. The fewer parameters that are modified, the faster the tool will run.
All coordinate formats are on by default. If you want to extract custom locations only and do not want to extract spatial coordinates, turn off the coordinate format parameters.
If an Adobe PDF document is provided as input and its content includes a spatial coordinate in a format that is turned on, and the output feature class does not contain a feature representing the spatial coordinate, your computer may not have a component that is required to process PDF documents.
When you use a custom location file to extract place names, it is a best practice to specify fewer place names in the file. For example, if you convert a feature class representing all places in the world to a custom location file, the process can take a lot of time looking for places that are unlikely to be present or are in areas of the world in which you are not interested for your analysis.
When the place names in which you are interested can be misspelled or have known variations, you will typically get better results by specifying common misspellings and alternate place names in the custom location file instead of using fuzzy matching. When fuzzy matching is turned on, you will get an output location if 70 percent of the characters in a place name have a match with the input content. This can produce more false positives than if you provide known alternates and misspellings.
A useful workflow for fuzzy matching is to first run the tool with fuzzy matching turned off. Then, run the tool again with fuzzy matching turned on and check the results. This can help you identify spelling variations that can be added to a custom locations file.

coord_use_lonlat (オプション) | When numbers resemble x,y coordinates, both numbers are less than 90, and there are no symbols or notations to indicate which number represents the latitude or longitude, results can be ambiguous. Interpret the numbers as a longitude-latitude coordinate (x,y) instead of a latitude-longitude coordinate (y,x).

| Boolean |
date_yyjjj (オプション) | Specifies whether to search for dates in which numbers are in the YYJJJ or YYYYJJJ format (frequent false positives). 03132 and 97015 are examples.
| Boolean |
max_dates_extracted (オプション) | The maximum number of dates that will be extracted. | Long |
ignore_first_dates (オプション) | The number of dates that will be detected and ignored before extracting all other dates. | Long |
date_range_begin (オプション) | The earliest acceptable date to extract. Detected dates matching this value or later will be extracted. | Date |
date_range_end (オプション) | The latest acceptable date to extract. Detected dates matching this value or earlier will be extracted. | Date |
in_custom_attributes (オプション) | The custom attribute file (.lxtca) that will be used to scan the input content. Fields will be created in the output feature class's attribute table for all custom attributes defined in the file. When the input content is scanned, it will be examined to see if it contains text associated with all custom attributes specified in the file. When a match is found, the appropriate text is extracted from the input content and stored in the appropriate field. | File |
file_link (オプション) | The file path that will be used as the file name in the output data when the Input File parameter (in_file in Python) is transferred to the server. If this parameter is not specified, the path of the Input File will be used, which may be an unreachable folder on a server. This parameter has no effect when the Input File is not specified. | String |
file_mod_datetime (オプション) | The UTC date and time that the file was modified will be used as the modified attribute in the output data when the Input File parameter (in_file in Python) is transferred to the server. If this parameter is not specified, the current modified time of the input file will be used. This parameter has no effect when the Input File is not specified. | Date |
pre_text_length (オプション) | Content is extracted from the input document to provide context for the location that was found. This parameter defines the maximum number of characters that will be extracted preceding the text that defines the location. The extracted text is stored in the Pre-Text field in the output feature class's attribute table. The default is 254. The Pre-Text field's data type will also have this length. The length of a text field in a shapefile is limited to 254 characters; when the output is a shapefile, a larger number of characters will be truncated to 254. | Long |
post_text_length (オプション) | Content is extracted from the input document to provide context for the location that was found. This parameter defines the maximum number of characters that will be extracted following the text that defines the location. The extracted text is stored in the Post-Text field in the output feature class's attribute table. The default is 254. The Post-Text field's data type will also have this length. The length of a text field in a shapefile is limited to 254 characters; when the output is a shapefile, a larger number of characters will be truncated to 254. | Long |
std_coord_fmt (オプション) | Specifies the coordinate format that will be used to store the coordinate location. A standard representation of the spatial coordinate that defines the point feature is recorded in a field in the attribute table.
| String |
req_word_breaks (オプション) | Specifies whether to search for text using word breaks. A word break occurs when words (text) are bounded by whitespace or punctuation characters as in European languages. This setting can produce frequent false positives or infrequent false positives depending on the language of the text. For example, when word breaks are not required, the English text Bernard will produce a match against the text San Bernardino, which would likely be considered a false positive. However, when text is written using a language that does not use word breaks, you cannot find words if word breaks are required. For example, with the text I flew to Tokyo in Japanese, 私は東京に飛んで, you would only be able to find the word Tokyo, 東京, when word breaks are not required.
