ALI to RCL 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 RCL Road Centerline Synchronization quality control (QC Quality Control) check identifies where the Automatic Location Information (ALI) address data is inconsistent with Road Centerline (RCL) address data.

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.

To run this check, an ALI table and road centerline feature class are required.

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

The following parameters can be specifically configured for the ALI to RCL 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.

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

  • ALI - Address Number Suffix*: Represents the ALI record's address number suffix.

  • 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.

  • Telephone Number (Tel)*: Represents the telephone number of an ALI record.

  • 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.

  • Road Centerline (RCL) Layer Name: The name of the road centerline layer.

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

  • RCL - Left Address Number Prefix: Represents the address number prefix on the left side of the road segment.

  • RCL - Right Address Number Prefix: Represents the address number prefix on the right side of the road segment.

  • RCL - Left FROM Address: Represents the address number on the FROM node on the left side of the road segment.

  • RCL - Left TO Address: Represents the address number on the TO node on the left side of the road segment.

  • RCL - Right FROM Address: Represents the address number on the FROM node on the right side of the road segment.

  • RCL - Right TO Address: Represents the address number on the TO node on the right side of the road segment.

  • RCL - Parity Left: Indicates whether the left side of the road segment contains odd, even, both, or zero address range values.

  • RCL - Parity Right: Indicates whether the right side of the road segment contains odd, even, both, or zero address range values.

  • RCL - 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.

  • RCL - ESN Left: Represents the Emergency Service Number (ESN) on the left side of the road segment.

  • RCL - ESN Right: Represents the Emergency Service Number (ESN) on the right side of the road segment.

  • RCL - MSAG Community Name Left: Represents the MSAG Community name on the left side of the road segment.

  • RCL - MSAG Community Name Right: Represents the MSAG Community name on the right side of the road segment.

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

*When configuring the Address Prefix, Address Number Suffix, or Telephone Number, Address in the extended information of the fallout report is populated if a value exists in the Address field for a particular record. In the following examples, we will use address 1600 Venice Blvd, and how it will appear if the correct field has been configured and a value exists for that address.

Table 1. ALI to RCL Synchronization Check Configuration and Fallout Result Examples
Example Type Field Value Fallout Report Result
ALI - Address Number Prefix Address Prefix = 3W2N- Address: 3W2N-1600 Venice Blvd.
ALI - Address Number Suffix Address Number Suffix = B Address: 1600 B Venice Blvd.
ALI - Address Number Suffix Address Suffix = 1/2 Address: 1600 1/2 Venice Blvd.
Telephone Number (Tel) Telephone Number (Tel) = 9876543 Address: 1600 Venice Blvd, Tel: 9876543.

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 road centerlines

  • Specific failure information – criteria causing ALI 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 ALI records or road centerline features. These features display up to the first 5 values listed in alphanumeric order. This list exists for the following features.

    • RCL’s Unique ID

    • RCL’s ESN

    • RCL’s MSAG Community

    • RCL's AdNumPre

  • Extended information providing more details about the fallout

The examples below shows possible error messages you may receive when a record fails the ALI to RCL Synchronization QC check. The extended information provides the detected and expected results when verifying that addresses in the ALI can be properly placed onto a corresponding road segment in the RCL layer. To view additional information on when a fallout record is generated, see ALI to RCL Synchronization Subchecks.

Here are examples of Fallout Report Records for the ALI to RCLQC Synchronization Checks.

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 cases, the ALI unique ID and telephone number is not provided and the ALI address should be used for identification.
