The two United States federal agencies, National Institute of Standards and Technology (NIST) and National Oceanic and Atmospheric Administration (NOAA) retired use of the “U.S. survey foot” on December 31, 2022. 1 International foot = 0.3048 meters 1 US survey foot = 0.3048006096 meters To most people, the difference is barely discernible and equates to approximately one-eighth of an inch per mile. However, surveyors who measure over long distances, the impact can be significant. The difference starts showing up on 2nd decimal place for lengths over 10,000. If US foot was used to survey distances, apply a multiplication factor of 1.000002 to convert to International foot.

The ArcGIS Roads and Highways Information Model is the core structure for linear referencing data. The package available for download in this blog, can be used to explain the LRS data model as applicable to R&H. This is intended to  explain and understand the basic building blocks of the solution as detailed below. The package contains the following items: File geodatabase containing LRS model and configuration LRS report containing schema details and LRS configuration metadata The model evolves as new capabilities get added. Hence, the following packages are being provided corresponding to major, long-term releases:    R&H Information Model for ArcGIS Pro 3.3:  LRS33RH_Package.zip R&H Information Model for ArcGIS Pro 3.1: LRS31_Package.zip LRS Model The LRS Schema is comprised of the following feature classes and tables: Centerline: Centerline    Calibration Point: Calibration_Point Redline: Redline Centerline Sequence: Centerline_Sequence (table) The following LRS entities can be added on as needed for the modelling exercise: Networks Line Network: Line_Net Derived Network: Derived_Net (optional) Events Point Event: Point_Ev Range Event: Range_Ev Station Equation Event: Station_Ev (optional) Intersection Hydrology Intersection: Hydro_Int uses ‘GeoLayers/Rivers’ as the intersecting layer (optional) Address Address Range Event : AddressRange_Ev uses ‘SiteAddressPoint’ as the Site Address Feature (optional) LRS Report The LRS Report is comprised of the following: LRS33RH: schema report (HTML, json, PDF, Excel formats) lrs33RH_Metadata: LRS configuration metadata (XML format) Conclusion You can use R&H tools to create or load data to the geodatabase included, to further your understanding and proof of concept efforts. R&H’s flexible information model allows you to model your own network, event and intersection feature classes. The package is not intended to be organization specific or implementation ready. However, it does provide the core structure to get you started. More comprehensive data models and their implementation practices can be found at Esri Community and related resources. ... View more
