The feature object identifier (FOID) is composed of an agency id, a subdivision id, and an id number. This is displayed in the applications as a string composed of the agency code, id number, and subdivision id (e.g. "1C 0000000001 00001"). Internally, the database stores these three values as a single encoded number (e.g. 2025493936704847873). Most APIs use or return the internal foid number for performance reasons. The following functions convert foids from one format to another.
Function | Description |
|---|---|
FoidNumberToString | Converts a FOID as a number to a FOID as a display string. |
FoidStringToNumber | Converts a FOID as a display string to the internal FOID number format. |
