Description: ObjectiveThe objective of the Bridges feature class is to document the location and characteristics of pedestrian bridges within Bozeman Pond Park. These structures are essential components of the park’s circulation network, supporting safe pedestrian movement, accessibility, maintenance planning, and long‑term infrastructure management.Equipment UsedData for this feature class was collected using an Emlid RS2 Multi‑GNSS receiver, capable of receiving corrections from multiple satellite constellations to achieve high‑accuracy positioning.Mapping TechniquesBridges were mapped as point features by occupying accessible bridge corners or central points with the GNSS receiver. Averaged GNSS positions were used to improve positional stability and reduce noise. All bridges were accessible in the field, so no offsets were required. Logging was performed at a consistent interval to ensure uniform data quality.Base StationNo base station or differential correction was used for this dataset. All positions were collected in autonomous GNSS mode, resulting in standard, uncorrected accuracy.EditingMinimal editing was required for this feature class. Points were visually inspected in ArcGIS Pro to confirm correct placement relative to aerial imagery. No vertices were moved, and no multipath spikes or anomalies were detected. No heads‑up digitizing or reconstruction was necessary.Estimated AccuracyBased on the project’s data quality assessment, the bridges feature class achieved an estimated horizontal accuracy of approximately 1–2 meters at a 95% confidence level, consistent with expectations for RS2 GNSS data corrected using a nearby base station.Spatial ReferenceThe spatial reference for this feature class is: NAD 1983 2011 StatePlane Montana FIPS 2500 (Meters)Coordinate System: ProjectedDatum: NAD 1983 (2011)Projection: StatePlane Montana FIPS 2500Linear Unit: MetersFields (Domain and Entity Information)MATERIALDescription: Primary construction material of the bridge.Type: Text (coded)Domain: Wood, Metal, Composite, OtherCONDITIONDescription: Physical condition of the bridge at the time of inspection.Type: Text (coded)Domain: Excellent, Good, Fair, PoorACCESSIBLEDescription: Indicates whether the bridge meets accessibility considerations.Type: Text (coded)Domain: Y, NLAST_INSPECTIONDescription: Date the bridge was last inspected.Type: DateDomain: Valid calendar datesMAINTENANCE_PRIORITYDescription: Indicates the urgency of maintenance needs.Type: Text (coded)Domain: High, Medium, LowNOTESDescription: Optional comments or observations about the bridge.Type: TextDomain: Free text
