FromDate FromDate Date 8 0 0 In Esri's Roads and Highways, the FromDate field is a temporal date-and-time attribute that defines the exact date and time when an LRS feature (such as a route, centerline, or event) officially became operational or active Together with the ToDate field, FromDate facilitates time awareness and time slicing. It dictates how geographic and attribute data are queried, edited, and visualized over time: LRS Network properties Marks the beginning of a feature’s lifespan in the database ToDate ToDate Date 8 0 0 In Esri's Roads and Highways, the ToDate field is a temporal date-and-time attribute that defines the exact date and time when an LRS feature (such as a route, centerline, or event) officially ceased to be operational, active, or valid. The ToDate field acts as the closing boundary for a feature's lifecycle within the Linear Referencing System (LRS) LRS Network properties (https://doc.esri.com/en/arcgis-pro/latest/help/production/roads-highways/view-lrs-network-properties.html) Marks the end of a feature’s active lifespan. EventID EventID String 38 0 0 In Esri's Roads and Highways, the EventID field is a system-enforced, alphanumeric identifier that uniquely distinguishes a specific logical asset or business attribute (such as a speed limit, pavement condition, or sign) across its entire temporal lifecycle. The EventID represents the asset, not just the individual database row. When a route undergoes a realignment or an asset attribute changes, Roads and Highways executes a time slice. This retires the old row (populating ToDate) and creates a new row (populating FromDate). Both rows will retain the exact same EventID so that the asset's history remains fully traceable over time. https://doc.esri.com/en/arcgis-pro/latest/help/production/location-referencing-pipelines/external-event-registration.html A unique, system-generated alphanumeric identifier (typically a GUID or UUID) assigned to each distinct event or record. RouteID RouteID String 255 0 0 In Esri's Roads and Highways, the RouteID field is a system-enforced, unique identifier that binds all the architectural elements of the Linear Referencing System (LRS) together. It maps a linear feature (the route) directly to its underlying geometry (centerlines) and its overlaid business assets (events). The RouteID uniquely distinguishes a specific travel path or roadway entity within a given LRS Network. https://doc.esri.com/en/arcgis-pro/latest/help/data/linear-referencing/introduction-to-routes-and-route-feature-classes.html A unique, system-generated alphanumeric identifier that establishes the unique identity of a linear route within the network. FromMeasure FromMeasure Double 8 0 0 In Esri's Roads and Highways, the FromMeasure field (internally mapped during event configuration as the measure_field parameter) is a numeric attribute that defines the exact linear starting distance along a route where an LRS asset, point of interest, or business event begins. By definition, the value in FromMeasure must be less than or equal to the value in the ToMeasure field for monotonically increasing routes, preserving the topological integrity of the travel corridor. For Line Events: It marks the strict beginning boundary of a linear asset segment (e.g., the starting point of a speed limit zone, paving material, or construction project). For Point Events: It serves as the single, definitive location measure indicating exactly where a distinct point asset resides along the route (e.g., an individual highway sign, culvert, or accident location). Dataset unit of measure = miles Esri ArcGIS Location Referencing system schemas, tool references, and workflow guides for ArcGIS Pro 3.3+ and Enterprise 11.3 A numeric value indicating the starting location or measure of a linear event or segment along a specific route. ToMeasure ToMeasure Double 8 0 0 In Esri's Roads and Highways, the ToMeasure field (internally mapped during event configuration as the to_measure_field parameter) is a numeric attribute that defines the exact linear ending distance along a route where a line asset, restriction, or business event concludes. In standard increasing routes, the value in ToMeasure must be strictly greater than the value in FromMeasure to ensure topological validity along the corridor. While mandatory for line events, this field is completely omitted or left blank (<Null>) for point events, as points exist exclusively at a single measure (FromMeasure). Dataset unit of measure = miles Esri Create LRS Event Tool Reference, ArcGIS Pro Events Data Model Guide A numeric value indicating the ending location or measure of a linear event or segment along a specific route.

Federal Highway Administration (FHWA) Highway Performance Monitoring System (HPMS) Field Manual An alphanumeric string or code designating the specific federal Highway Performance Monitoring System (HPMS) data element or narrative requirement mapped to the LRS segment. LocError LocError String 100 0 0 In Esri's Roads and Highways, the LocError (Location Error) field is a system-populated text attribute within an LRS Event table that flags and describes the data quality or spatial status of an event feature. The LocError field serves as an automated quality control tracker. When you create, append, or modify LRS event data using ArcGIS Pro tools or web apps like the ArcGIS Event Editor, the system automatically validates the asset's measure locations against the underlying route. Any string value other than No Error signals a structural problem with that asset row. Features with location errors may not render spatially on your map (dynamic segmentation fails) or may behave unpredictably during route adjustments. The LocError field is explicitly system-managed and read-only within clients like the ArcGIS Event Editor. You cannot manually type into it; rather, it updates itself when you fix the underlying measure or date problem and refresh or reconcile your layers Esri Location Errors Analysis Guide, ArcGIS Event Editor Frequently Asked Questions A descriptive alphanumeric text string or numeric value detailing a specific linear referencing system (LRS) alignment issue, event orphan status, or spatial mismatch. FromReferentMethod FromReferentMethod SmallInteger 2 0 0 In Esri's Roads and Highways, the FromReferentMethod field is a system-managed attribute within an LRS Event table that identifies the specific engineering or linear method used to capture and calculate the starting location of an asset. When a cartographic or real-world realignment changes the length of a highway, standard measures shift. By storing how the feature was originally located via FromReferentMethod, the LRS can automatically recalculate the exact point on the new map using offsets from physical markers (like intersections or signs) rather than breaking the data link. This field uses a pre-configured Geodatabase Coded Value Domain named dReferentMethod. This domain is automatically generated by Roads and Highways. The system populates it when edits are committed using the ArcGIS Event Editor or ArcGIS Pro tools. Different rows in the exact same event table can use completely distinct linear referencing methods. Esri Storing Referent and Offset Information Reference Guide, Esri Enable Referent Fields Tool Reference, sri View LRS Event Properties Documentation dReferentMethod LaDOTD FromReferentLocation FromReferentLocation String 255 0 0 In Esri's Roads and Highways, the FromReferentLocation field is a system-managed text attribute within an LRS Event table that stores the unique name, ID, or description of the specific physical asset or landmark feature from which the event's starting position is derived. Instead of defining an event's start using only a raw, shifting route measure, this field permanently logs the name or primary key of the physical reference feature. Common examples include intersection names (e.g., "Main St & 5th Ave"), reference marker post IDs (e.g., "MP 42"), or asset IDs (e.g., "Sign_94021"). If a highway is physically realigned or shortened, its linear measures shift. Because the system preserves the exact real-world anchor name in the FromReferentLocation field, the LRS software can dynamically recalculate the correct coordinates and new FromMeasure values without breaking or corrupting the asset's relational location. For Point Events: This field captures the sole reference anchor for the point feature. For Line Events: This field captures the starting anchor of the linear segment, while a companion field called ToReferentLocation captures the ending anchor. Esri Storing Referent and Offset Information Reference Guide, ArcGIS Pro Events Data Model Specifications, Esri Enable Referent Fields Tool Parameter Reference A text description or structured string identifying the starting referent landmark and its associated spatial offset used to locate the beginning of a linear event. FromReferentOffset FromReferentOffset String 50 0 0 In Esri's Roads and Highways, the FromReferentOffset field is a system-managed numeric attribute within an LRS Event table that stores the precise linear distance from a known physical landmark (FromReferentLocation) to the actual starting point of an LRS event or asset. Assets are rarely positioned perfectly on top of intersections or mile markers. This field captures how far before or after that reference landmark the asset begins. For example, if a speed limit change occurs 500 feet past Mile Marker 42, the offset field stores that 500 unit value. The values can be positive or negative numbers. A positive offset indicates a distance moving forward in the direction of increasing route measures, while a negative offset indicates a distance moving backward against the direction of calibration. When real-world construction or map alignments change the underlying route lengths, raw measures shift. Because the system retains the fixed landmark name and this specific offset distance, the Roads and Highways software can run its structural equations to reposition the asset and calculate its new FromMeasure automatically. For Point Events: This field stores the single offset value required to locate the point asset relative to its anchor. For Line Events: This field establishes the starting point's offset, while a companion field named ToReferentOffset maps the terminating boundary offset. Esri Storing Referent and Offset Information Reference Guide, ArcGIS Pro Events Data Model Specifications, Esri Enable Referent Fields Tool Parameter Reference A numeric value representing the precise displacement or distance from the designated starting referent landmark to the actual beginning of the linear event. ToReferentMethod ToReferentMethod SmallInteger 2 0 0 In Esri's Roads and Highways, the ToReferentMethod field is a system-managed attribute within an LRS Line Event table that identifies the specific engineering or linear referencing method used to capture and calculate the ending (terminal) location of a linear asset. This field is only utilized for Line Events (such as pavement condition segments or speed limit zones). It is omitted or left blank (<Null>) for Point Events, as points do not possess an ending boundary. By capturing how the end of an asset was originally located (e.g., via an intersection, engineering station, or mile marker), the LRS can dynamically recalculate the ending position (ToMeasure) if the underlying road network undergoes a physical or cartographic realignment. This field is controlled by the same pre-configured Geodatabase Coded Value Domain named dReferentMethod that governs the starting method. The values are automatically maintained when edits are made via the ArcGIS Event Editor or ArcGIS Pro tools. Esri Storing Referent and Offset Information Reference Guide, ArcGIS Pro Events Data Model Specifications, Esri Enable Referent Fields Tool Parameter Reference dReferentMethod LaDOTD ToReferentLocation ToReferentLocation String 255 0 0 In Esri's Roads and Highways, the ToReferentLocation field is a system-managed text attribute within an LRS Line Event table that stores the unique name, ID, or description of the specific physical asset or landmark feature from which the event's ending (terminal) position is derived. This field is strictly mandatory for Line Events (e.g., a specific pavement project segment or functional classification zone). It is omitted or left blank (<Null>) for Point Events, as point features have no terminal boundary. It records the permanent identity of the physical asset or landmark that defines where the asset stops. Common entries include a terminal intersection name (e.g., "State Route 12 & County Rd 4"), a reference post ID (e.g., "MP 47.5"), or an engineering structure asset key. If the physical road network is shortened, lengthened, or re-calibrated, raw measures change. Because the system holds the immutable text string of the ending landmark in ToReferentLocation, the LRS software can dynamically re-compute the new ending coordinate and update the ToMeasure field automatically without losing or corrupting the feature's relational endpoint. Esri Enable Referent Fields Tool Parameter Reference, Storing referent and offset information for event locations, Esri LRS Events Data Model Guide A text description or structured string identifying the ending referent landmark and its associated spatial offset used to locate the termination of a linear event. ToReferentOffset ToReferentOffset String 50 0 0 In Esri's Roads and Highways, the ToReferentOffset field is a system-managed numeric attribute within an LRS Line Event table that stores the precise linear distance from a known physical terminal landmark (ToReferentLocation) to the actual ending point of the LRS line event. Much like its partner field, this is used strictly for Line Events to establish where the linear segment physically terminates relative to a real-world object. It is omitted or left blank (<Null>) for Point Events. Linear assets rarely stop perfectly on top of an intersection or milepost. This field logs that exact gap. For example, if a lane restriction ends 300 feet before an upcoming intersection landmark, this field captures that exact relative value. This field accepts both positive and negative values. A positive offset shifts the calculated endpoint forward (in the direction of increasing route measures), while a negative offset shifts the endpoint backward (against the direction of route calibration). When real-world roadway realignments alter underlying route lengths, raw measure positions shift. Because the system preserves the fixed terminal landmark name and this specific offset distance, the Roads and Highways software can rerun its structural equations to reposition the asset and calculate its new ToMeasure automatically.
