Reference data is one of the key elements in a locator. Knowing which address elements are needed for the locator role used to create the locator is key to formatting the reference data.
Formatting the reference data
The elements described below are used to format reference data.
Address elements
ArcGIS Pro includes several predefined locator roles that have specific requirements for the primary reference data it can use to match addresses. You can use data from your organization or from other data providers, but they each contain some common address elements that are required to build a locator. These address elements must be divided into multiple fields in the attribute table of the reference data. Common address elements and their descriptions are shown in the following table:
| Element | Description |
|---|---|
| Left house number range | A low number and a high number of the address range for the left side of the street, such as 100, 198 |
| Right house number range | A low number and a high number of the address range for the right side of the street, such as 101, 199 |
Left parity | The odd, even, or mixed house number range value on the left side of the street, such as O, E, or B |
Right parity | The odd, even, or mixed house number range value on the right side of the street, such as O, E, or B |
