The template file ( *.lxttmpl) that determines the setting to use for each tool parameter. This can help you identify spelling variations that can be added to a custom locations file. Then, run the tool again with fuzzy matching turned on and check the results. This can produce more false positives than if you provide known alternates and misspellings.Ī useful workflow for fuzzy matching is to first run the tool with fuzzy matching turned off. 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. 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. 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 you use a custom location file to extract place names, it is a best practice to specify fewer place names in the file. 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. If you want to extract custom locations only and do not want to extract spatial coordinates, turn off the coordinate format parameters. The fewer parameters that are modified, the faster the tool will run.Īll coordinate formats are on by default. Default values can be modified for each parameter. The parameter default values are designed to optimize the identification of coordinates and dates. 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.A custom location file associates a place name with a spatial coordinate representing that location. Recognizes place names specified in the text that are defined in a custom location file 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 spatial coordinates specified in the content of the text and creates points representing these locations.The tool analyzes and processes the text as follows: The tool extracts locations found in the text or in the content of the file and adds the resulting points to a feature class. 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. If the input text is a file path, the identified file will be opened and its content will be analyzed. ![]() Analyzes input text or a text file and extracts locations to a point feature class
