Summary

Analyzes input text or a text file and extracts locations to a point feature class

If the input text is a file path, the identified file will be opened and its content will be analyzed. If the input text is unstructured information such as an email message, or semistructured text such as a travel forms, the input text itself will be analyzed. The tool extracts locations found in the text or in the content of the file and adds the resulting points to a feature class.

The tool analyzes and processes the text as follows:

  • Recognizes spatial coordinates specified in the content of the text and creates points representing these locations. The following coordinate formats are recognized: decimal degrees, degrees decimal minutes, degrees minutes seconds, Universal Transverse Mercator, and Military Grid Reference System.
  • Recognizes place names specified in the text that are defined in a custom location file and creates points representing these locations. A custom location file associates a place name with a spatial coordinate representing that location.
  • Recognizes text that is of interest, extracts this information from the text provided, and records it in fields in the output feature class's attribute table.

Usage

  • 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.

Parameters

LabelExplanationData Type
Input Text or File Path

The text that will be scanned for locations (coordinates or custom locations), dates, and custom attributes; or text defining a file path, whose contents will be scanned for locations. For geoprocessing services, when a file path is provided, the file must be accessible from the service, as the file is not transferred to the server.

String
Output Feature Class

The feature class containing point features that represent the locations that were found.

Feature Class
Input Template
(Optional)

The template file (*.lxttmpl) that determines the setting to use for each tool parameter. When a template file is provided, all values specified for other parameters will be ignored except those that determine the input content that will be processed and the output feature class.

Some settings that are available in the Extract Locations pane are only available to this tool when the settings are saved to a template file, and the template file is referenced in this parameter. These settings are as follows:

  • Spatial coordinates in x,y format—Allows two sequential numbers such as 630084 4833438 or 981075.652ftUS 607151.272ftUS to be recognized as coordinates when they are valid for a planar coordinate system associated with the input documents. You can specify whether numbers with and without units are recognized or only numbers with units of measure are recognized as coordinates.
  • Custom coordinate and date formats—Allows you to customize how text is recognized as a spatial coordinate or a date, particularly when written in a language other than English or using a format that is not common in the United States. For example, a spatial coordinate written as 30 20 10 N x 060 50 40 W can be recognized with a customization to recognize the character x as valid text between the latitude and longitude. Coordinates and dates such as 60.91°N, 147.34°O and 17 juillet, 2018 can be recognized when customizations are specified to accommodate the language of the documents, in this case French. Also, when two-digit years are used, you can control the range of years to which they are matched.
  • Preferences for some ambiguous dates—Dates such as 10/12/2019 are ambiguous because they can be interpreted as either October 12, 2019, or December 10, 2019. Some countries use the m/d/yy date format as a standard, and other countries use the d/m/yy format. A preference can be set for how these ambiguous dates are interpreted, either as m/d/yy or d/m/yy, to suit the country of origin of the documents.
  • Length of fields in the output feature class—You can specify the length of the fields containing text surrounding spatial coordinates that are extracted from a document using the Pre-Text Field Length (pre_text_length in Python) and Post-Text Field Length (post_text_length in Python) parameters. The Extract Locations pane allows you to control the length of several additional fields in the attribute table, including fields containing dates extracted from the document, the original text that was converted to dates, the file name from which the information was extracted, and so on.

Date
Latest Date Of Acceptable Date Range
(Optional)

The latest acceptable date to extract. Detected dates matching this value or earlier will be extracted.

Date
Input Custom Attributes
(Optional)

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
Input File Link Text
(Optional)

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
Input File Date and Time
(Optional)

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 Field Length
(Optional)

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 Field Length
(Optional)

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
Coordinate Format
(Optional)

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.

  • DD - Decimal DegreesThe coordinate location is recorded in decimal degrees format. This is the default.
  • DM - Degrees Decimal MinutesThe coordinate location is recorded in degrees decimal minutes format.
  • DMS - Degrees Minutes SecondsThe coordinate location is recorded in degrees minutes seconds format.
  • UTM - Universal Transverse MercatorThe coordinate location is recorded in Universal Transverse Mercator format.
  • MGRS - Military Grid Reference SystemThe coordinate location is recorded in Military Grid Reference System format.
String
Require Word Breaks
(Optional)

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.

  • Checked—The tool will search for words that are bounded by whitespace or punctuation characters. This is the default.
  • Unchecked—The tool will not search for words that are bounded by whitespace or punctuation characters.
