The source data for User Dictionaries includes street data but can also include place names and intersections.
To create a User Dictionary, your source data must conform to the following requirements:
- Source records must include required fields, and these fields are mapped during the User Dictionary creation process. If a value of a required field is empty for a particular record, then that record will not be imported into the User Dictionary. Required fields may vary for different countries. The MapInfo® table must contain specific fields, which GeoStan™ then uses to convert the table into the dictionary format. These input fields are described in Required input fields.
- Source records must be in a MapInfo table (TAB file). The TAB file requirements vary for different countries.
- Segments must have two or more defined endpoints to be loaded into a User Dictionary. Segments without endpoints are ignored.
- Segments that make up intersections must have one or more end points in the intersection for GeoStan to recognize it as an intersection. Source records can be either point objects or segments.
- Each row in the table is equivalent to a street segment.
