LRS_ID is the unique identifier for the roadway feature used to support linear referencing

LRS_ID structure allows for both common and unique identification. (same road unique type)

LRS ID SetupState Maintained Roads

STATE MAINTAINED ROADS

XXX-XX-F-LLL

The LRS ID for state maintained roads will be created from the existing five-digit Control Section number including adash between the third and fourth digit (XXX-XX), a dash (-), the one-digit Feature Type code (F), a dash (-), and athree-digit number representing the sequential occurrence of the feature (LLL).

Note: All state maintained roads will have a twelve (12) character LRS ID which will remain as a fixed identificationnumber for each roadway segment.

LRS ID SetupNon-State Maintained Roads

NON-STATE MAINTAINED ROADS

PPPXNNNNNNTTTSFLLL

The LRS ID for non-state maintained roads will be created from the three-digit Parish FIPS number (PPP), the one-digitPrefix Code number (X), the six-digit Road Name Code number (NNNNNN), the three-digit Street Type Code number(TTT), the one-digit Suffix Code number (S), the one-digit Feature Type code (F), and a three-digit number representingthe sequential occurrence of the feature (LLL). Discontinuous roadway segments of the same name within the sameParish will be unique based on the sequential occurrence number. The Parish FIPS number is determined based on thephysical location of the road. The Street naming conventions are found in the existing TIGER data. The Feature Typemust be derived from information provided in this document.

Note: All non-state maintained roads will have an eighteen (18) character LRS ID which will remain as a fixedidentification number for each roadway segment.

Mapping Process

Base Maps Are Updated Periodically

A GeoPdf Is an Interactive PDF Where One Can Select aFeature on the Map and See Its Attribute Data

A Free Toolbar Can Be Downloaded Which Will AllowAnyone to Red-Line the Map Indicating any Correctionsor Additions Necessary

This GeoPdf Can Be Returned to the Mapping Unit,Imported into the GIS Map, Comments Reviewed, EditsMade, And then an Updated Map Can Be Created andDistributed

Completed Maps Will Be Sent to the Local GovernmentOfficials for Certification that the Map is Correct andReturned to the Mapping Unit

Certified Maps Will Be Filed Until they Require MajorChanges

Uncertified Maps Should be Returned for Corrections.Once Changes Are Made, the Process Will be Repeated

used to create GeoPDFs for external use. The data attributes

are embedded in the GeoPDF from the ArcMap application.

Whether it is for field inventory or local government use, TerraGo

Toolbar is a free user friendly application that enables quick

interaction from field to office providing more accurate, real-time

decision making.

Collaboration of State and Local Governmentto Maintain and Distribute a Statewide Roadway Feature

As part of the plan to support collaboration between state and localgovernment, DOTD has created this roadway feature to be used withcurrent technologies to enable interaction between state offices and local

agencies to maintain the most accurate data for reporting efforts.

With current reductions in workforce, DOTD must rely on assistance tomaintain these roadway features. DOTD is required to submit reports tothe Federal Highway Administration. The accuracy of these reports affectfunding which is the return to the local agencies.

The most important issue that must be addressed is to determine ownershipof roadways and eliminate linear features that are not roads based on theearlier definition. This can only be done by state and local governmentagencies working together.

What Can You Do?

Collaboration Between DOTD and Local Government OfficialsIs Crucial to Maintain Accurate Maps Reflecting Roadway,Boundary, and Name Changes

You, at the Districts, Have More Contact and Relationships

With the Local Governments

The Cartographic Unit Needs Your Assistance to Improve TheirContacts With the Local Government Personnel

You Also Have the Best Knowledge of the Roads and the Citiesor Communities in Your Area

What Can You Do?

Base Map Roadway Feature Contains Roads WhereOwnership Has To Be Verified; Public Road, Private Road orNOT A ROAD

Assist the Cartographic Unit by Reviewing the Maps VeryClosely and Identify Necessary Corrections and ProvideInformation Concerning the Corrections.

Likewise You Can Assist the Data Collections Units by

Notifying Them of Any Known Discrepancies in Data
