ALI to SSAP Synchronization

The ALI Automatic Location Identification. An enhanced electronic location system that automatically relays a caller's address when they call an emergency responder service such as 9-1-1. to SSAP Site Structure Address Point Synchronization quality control (QC Quality Control) check identifies where Automatic Location Information (ALI) address data is inconsistent with Site/Structure Address Points (SSAP's) by processing ALI records through a series of checks to ensure they are present in the SSAP layer.

Note: Synchronization QC checks can have leading zeros in the Emergency Service Number (ESN Emergency Service Number. A three to five digit number representing a unique combination of emergency service agencies (law enforcement, fire and emergency medical service) designated to serve a specific range of addresses within a particular geographical area, or Emergency Service Zone (ESZ). The ESN facilitates selective routing and selective transfer, if required, to the appropriate PSAP and dispatching of the proper service agency(ies).) fields for any of the layers or tables used in the QC check. The leading zeros will not negatively affect the comparison and an accurate fallout for the synchronization check is created, including accurately displaying your data with any leading zeros.

Note: For all field comparisons, null and empty/blank values are considered equal values. This includes ESN, Community, and street name field comparisons. For example, in ALI to SSAP Synchronization, if an ALI record and its associated address point have an ESN of null and blank respectively, this will not cause a fallout as neither record contains an ESN. To create a fallout for a required field when it does not contain a value, utilize the Null Value in Field check.

To run this check, the following are required.

  • ALI table
  • SSAP feature class

Configurations for QC check parameters contain filters to prevent selecting incompatible field types.

The following required parameters can be specifically configured for the ALI to SSAP Synchronization QC check.

  • Run On: Non-configurable. This QC check inspects the target dataset.

  • Severity: Sets the importance level of this QC check’s fallouts. Critical fallouts prevent export package outputs but will still provide fallouts.

  • ALI Table Name: The name of the ALI table.

  • ALI - Reporting Unique ID: A unique identifier in the ALI table that can be used to uniquely identify a singular feature.

  • ALI - Address Number Prefix: Represents the ALI record's address number prefix. Populate this parameter to have address prefix information included in the extended information field of the fallout report if one exists.

    For example, if the Address Number Prefix is configured and the record includes a prefix value of 3W2N, the report will show 3W2N-1600 Venice Blvd in the extended information field, not 1600 Venice Blvd.

  • ALI - Address Number: Represents the ALI record's address number. May represent the address number prefix and address number when those values exist in one field.

    0 address numbers are significant and taken into account only when they contain AdNumPre values.

  • ALI - Address Number Suffix: Represents the ALI record's address number suffix. Populate this parameter to have address suffix information included in the extended information field of the fallout report if one exists.

    For example, if the Address Number Suffix is configured and the record includes a suffix value of B, the report will show 1600 B Venice Blvd in the extended information field, not 1600 Venice Blvd. Note that null, empty strings, or whitespace do not count as a value.

  • ALI - Street Full Name: A list of street name fields that form the entire street name. For example: LSt_PreDir, LSt_Name, LSt_Typ, LSt_PosDir.

  • ALI - Telephone Number (Tel): Represents the telephone number of an ALI record. Populate this parameter to include the ALI's telephone number in the fallout report's extended information field if one exists.

    For example, if the telephone is configured and the record includes a telephone value of 123-456-7890, the report will show 1600 Venice Blvd, Tel: 123-456-7890 in the extended information field, not 1600 Venice Blvd. Note that null, empty strings, or whitespace do not count as a value.

  • ALI - Additional Location: Represents additional location information of an ALI record. Should only be used when this field is expected to match the SSAP field.

  • ALI - Emergency Service Number (ESN): Represents the ALI record's Emergency Service Number (ESN).

  • ALI - MSAG Community: Represents the ALI record's Master Street Address Guide (MSAG) Community.

  • SSAP Layer Name: The name of the SSAP layer.

  • SSAP - Address Number Prefix: Represents the SSAP's address number prefix. Populate this parameter to have address prefix information included in the extended information field of the fallout report if one exists.

    For example, if the Address Number Prefix is configured and the record includes a prefix value of 3W2N, the report will show 3W2N-1600 Venice Blvd in the extended information field, not 1600 Venice Blvd.

  • SSAP - Address Number: Represents the SSAP's address number.

    0 address numbers are significant and taken into account only when they contain AdNumPre values.

  • SSAP - Address Number Suffix: Represents the SSAP's address number suffix.

  • SSAP - Street Full Name: A list of street name fields that form the entire street name. For example: LSt_PreDir, LSt_Name, LSt_Typ, LSt_PosDir.

  • SSAP Additional Location: Represents additional location information of an SSAP. Should only be used when this field is expected to match the ALI field.

  • SSAP - Emergency Service Number (ESN): Represents the SSAP's Emergency Service Number (ESN).

  • SSAP - MSAG Community: Represents the SSAP's Master Street Address Guide (MSAG) Community.

  • Case Sensitivity: Select Match Case to enable and maintain the integrity of upper or lower case text in your data. See Case Sensitivity.

The following information is included for this QC check's fallout output.

  • QC check name
  • Description of the QC check
  • Unique identifier of the ALI record not matching SSAP

  • Specific failure information – criteria causing ALI to SSAP comparison record to fail. The fallout message values are added to the Extended Information description field in the fallout report. The message identifies specific fallout messaging values to assist in the identification of mismatching fields for the ALI records and SSAP features. The extended information in the fallout report provides up to the first 5 ID values listed in alphanumeric order if applicable. ID's are provided for the following comparisons when multiple address points contain matching information against an ALI record:

    • Address Number Prefix

    • Address Number Suffix

    • ESN

    • MSAG Community

  • ALI records with identical full addresses, ESN, and Communities that trigger the same fallout (telephone and unique ID’s can be different) will cause the fallout message to be rolled up, listing the number of ALI records that have the same exact fallout. This makes the fallouts easier to review for ALI records that contain the same full address.

    Note that Summary Reports consider each ALI record as independent. For example, if five ALI records are grouped together into one fallout in the Fallout Report, the Summary Report still counts every fallout record (in this example five) and not the grouped count of one.

The examples below shows possible error messages you may receive when a record fails the ALI to SSAP Synchronization QC check. The extended information provides the detected and expected results when verifying that addresses in the ALI contains a corresponding address point in the SSAP layer.

Note: Note that if there are multiple results with identical results (e.g., same error with the same address), the records are grouped together in the report and a quantity is listed.

In these examples, multiple scenarios are shown defining when a record fails or passes the ALI to SSAP Synchronization QC check.

Here is an image showing examples of records that pass or fail the ALI to SSAP Synchronnization Check.
