Railway Rail Mapping & Surveying

Updated: Sep 19, 2023

Rail corridor mapping is the process of creating maps and collecting data for a specific section or "corridor" of a railway network, typically along the route of a single railway line or a group of closely related lines. The purpose of rail corridor mapping is to provide accurate information about the railway infrastructure, surrounding terrain, and potential obstacles, to support various activities such as route planning, maintenance and repairs, and safety management.


Rail corridor mapping may use a variety of technologies, including LiDAR, aerial photography, and ground-based surveys, to create a detailed and comprehensive picture of the railway infrastructure and its surroundings. The resulting maps may include information about the location and condition of the track, the position and type of signal systems, and the terrain and other features surrounding the railway, such as buildings, roads, and waterways.


The data collected through rail corridor mapping can be used to identify potential safety hazards, plan maintenance and repairs, and optimize rail operations. For example, it can help railway companies to identify areas where track maintenance is needed, or to plan the installation of new infrastructure, such as crossings or switches. It can also support safety management by identifying potential obstacles or hazards along the rail corridor, such as trees or structures close to the track, that could pose a risk to trains and passengers.

Advantages of using Mapping in Railway



Rail corridor mapping can offer several advantages for railway companies, transportation planners, and other stakeholders involved in rail infrastructure management. Here are some of the key advantages:


Improved safety: Rail corridor mapping can help identify potential hazards and obstacles along the railway line, such as encroachments or overhanging vegetation, that could pose a risk to trains and passengers. This information can be used to plan and implement safety measures, such as trimming vegetation or installing warning signs, to reduce the risk of accidents.


Better maintenance planning: By providing a detailed view of the track and surrounding infrastructure, rail corridor mapping can help identify areas where maintenance and repairs are needed, such as sections of the track that are worn or damaged. This information can be used to prioritize maintenance and repairs, reducing the risk of breakdowns and delays.


Optimized operations: Rail corridor mapping can help optimize railway operations by providing data on track layout, elevation, and other factors that can affect train speeds and fuel efficiency. This information can be used to plan more efficient train routes, reduce fuel consumption, and improve on-time performance.


Improved asset management: Rail corridor mapping can help railway companies to better manage their assets by providing information on the location and condition of infrastructure such as bridges, tunnels, and signals. This information can be used to plan maintenance and repairs, improve safety, and extend the lifespan of the assets



What is the Process:


Create custom flight plans with drones and aerial collections or order custom satellite image tasking in mono or stereo.


Generate Custom DTM and ortho mosaic from custom drone, aerial, and satellite stereo image collections.


Generate planimetric data from the drone, aerial, and satellite image collections.


Generate contour data from the DTM-generated data to a variety of contour intervals depending on the accuracy of the DTM.
