GIS Dashboard for RailwayLine Safety

 Requirements

1. key features that can be extracted and visualized from RGB data collected by drones for railway lines, along with standard accepted values for a dashboard suitable for use in GIS (Geographic Information System) software:

   1.     Track Alignment and Geometry:

   a.     Feature: Railway track centerline, curvature, and alignment.

   b.     Standard Values: Curvature radius, track gauge, track width, and alignment coordinates.

   2.     Track Condition Assessment:

   a.     Feature: Track defects, cracks, and wear.

   2. Standard Values: Severity of defects (e.g., minor, moderate, severe), length and width of defects, and coordinates of defect locations.

   3.     Vegetation Encroachment:

   1. Feature: Vegetation coverage along the railway corridor.
   2. Standard Values: Vegetation density (percentage coverage), distance from track centerline to nearest vegetation edge, and type of vegetation.

   4.     Infrastructure Mapping:

   1. Feature: Bridges, tunnels, level crossings, signal posts, and platforms.
   2. Standard Values: Type of infrastructure, dimensions (length, width, height), location coordinates, and condition assessment (e.g., good, fair, poor).

    

   5.     Obstruction Detection:

   a.     Feature: Objects or obstacles along the railway corridor.

   a.     Standard Values: Type of obstruction (e.g., debris, unauthorized structures), dimensions, distance from track centerline, and potential safety risk level.

   6.     Land Use and Land Cover:

   a.     Feature: Land use and land cover classification.

   b.     Standard Values: Land cover categories (e.g., urban, agricultural, water bodies), percentage coverage of each category within a defined area, and coordinates of land cover boundaries.

   7.     Safety Features:

   a.     Feature: Safety barriers, fencing, and warning signs.

   b.     Standard Values: Type of safety feature, location coordinates, distance from track centerline, and condition assessment.

   8.     Geospatial Context:

   a.     Feature: Integration with existing GIS data.

   b.     Standard Values: Georeferenced coordinates, projection system used, and accuracy assessment (e.g., Root Mean Square Error).

    

   For the dashboard in GIS software, these extracted features and standard values can be presented using visualizations such as Interactive maps displaying the railway corridor with overlaid features and their attributes.

    

   •      Graphs and charts showing the distribution and trends of various parameters (e.g., track defects, vegetation coverage) along the railway line.

   •      Tabular views listing the detailed attributes and characteristics of identified features.

   •      Color-coded layers representing different categories or severity levels of features (e.g., track defects, vegetation types) for easy interpretation.

   •      Statistical summaries providing key metrics and insights about the condition and status of the railway infrastructure.

    

   By incorporating these features and visualizations into a dashboard, railway infrastructure managers and decision-makers can effectively analyze, monitor, and manage the railway network in a GIS environment, supporting informed decision-making and proactive maintenance strategies.
