Description
Record a supplied urban/rural classification and source.
Geographic activity records depend on location precision, boundary vintage, observation time, population denominator and access-window conventions. A travel-time budget differs from actual accessibility, and rectangular cell area does not establish privacy. Local shares and labels need the original survey and spatial definitions.
Record a supplied urban/rural classification and source.
When to use this tool
Use Geographic Survey Urban Rural Source Key when you already have areaCode, classificationCode, classificationSource and need to record a supplied urban/rural classification and source.
How to use the tool and how it works
- Enter areaCode, classificationCode, classificationSource. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read token. Use the output convention below.
Enter areaCode, classificationCode, classificationSource using the field constraints below. Encode these values, in exactly that order, as a JSON array and return the serialized array as text in token. String values are preserved without trimming or external terminology lookup.1
| Input field | Meaning and units | Accepted input |

| classificationSource | Classification Source | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |

}Limitations and assumptions
- The result records supplied values without deriving settlement categories. Sources and asserted relationships are not independently authenticated.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Use the actual route, service schedule, survey frame and boundary source when assessing mobility or access. Review disclosure across the full spatial dataset and linked records; a location label or cell-size product is not a complete privacy method.
