Rail Mapping Services for Railway Asset Inventory, LiDAR Data and Corridor Documentation

Rail Mapping FAQs

• What are rail mapping services?

  Rail mapping services create a measurable digital record of railway corridors, tracks, right-of-way features, and visible infrastructure. Reality IMT combines Hi-Rail LiDAR, GPS/INS positioning, 360 imagery, photogrammetry, and geospatial processing to document existing corridor conditions.

• What information can be collected during a rail mapping project?

  Depending on the project scope, rail mapping may document track locations, signals, signs, crossings, poles, visible utilities, drainage features, vegetation, mile markers, structures, platforms, and other above-ground corridor assets. Required asset classes should be defined before data collection begins.

• How is Hi-Rail LiDAR data collected?

  LiDAR sensors, positioning equipment, and cameras are mounted to a Hi-Rail vehicle or another approved mobile platform. Data is collected while traveling through the corridor at speeds permitted by the railroad, access plan, equipment configuration, and required accuracy.

• Can rail mapping be performed on active railway corridors?

  Yes, subject to railroad authorization, track access, operating rules, required escorts, safety procedures, and scheduling. Reality IMT coordinates the technical data-capture requirements with the client and designated rail personnel.

• What deliverables are available?

  Deliverables may include registered LiDAR point clouds, GIS asset inventories, georeferenced imagery, 360 video logs, CAD or Civil 3D files, corridor geometry, asset reports, digital elevation data, and project-specific documentation.

• What file formats can be provided?

  Available formats may include E57, LAS or LAZ point clouds; DWG or Civil 3D files; Esri geodatabases or shapefiles; CSV asset tables; image and video files; and other project-specific formats. Final formats are confirmed during project scoping.

• How accurate is rail mapping data?

  Accuracy depends on the sensor configuration, collection speed, satellite visibility, control network, corridor conditions, processing method, and required deliverables. Accuracy requirements should be established before field collection so the appropriate methodology can be selected.

• Does rail mapping include track geometry measurements?

  Measurable track and corridor geometry can be extracted from LiDAR data when included in the project scope. Formal track-geometry inspection, regulatory compliance testing, or certification should be identified separately because these services may require specialized equipment, procedures, and qualifications.

• Can Reality IMT create a rail asset inventory or GIS database?

  Yes. Visible corridor assets can be identified, classified, and organized into a GIS-ready database with locations, asset types, imagery references, and other agreed attributes. The level of attribution depends on the project requirements and source data.

• Can 360 video be linked to maps or mile markers?

  Yes. Reality IMT can provide georeferenced rail video and 360 imagery connected to route maps, GPS locations, mile markers, or corridor segments through a web-based viewer or project-specific delivery platform.

• How long does a rail mapping project take?

  The schedule depends on corridor mileage, access windows, operating restrictions, collection speed, asset-extraction requirements, accuracy, deliverable formats, and review requirements. Reality IMT establishes the field and processing schedule after the corridor and deliverables are defined.

• What information is needed to prepare a rail mapping proposal?

  Provide the corridor location, approximate mileage, track access conditions, required assets, accuracy expectations, desired file formats, available control information, schedule, and intended use of the data. This allows Reality IMT to recommend the appropriate capture and processing approach.
