CORRIDOR MAPPING

Corridor mapping is a specialised application of remote sensing and geospatial technology that focuses on surveying and mapping linear features such as rivers, coastlines, roads, highways, railways, power lines, pipelines, and other infrastructure that stretch across the landscape. In general, corridor mapping demands greater accuracy and detail compared to wide area captures to meet engineering design specifications. Key components and techniques involved in corridor mapping include:

Aerial Photography and Lidar: These data are captured simultaneously along the entire length of the corridor to produce visually stunning digital-twins. These data capture the terrain, the built and natural assets within the corridor, and the potential hazards putting those assets at risk.

High-Precision Georeferencing: The collected spatial data is accurately georeferenced against highly sensitive onboard GNSS and IMU instruments. These data are then reference to a geographic coordinate system.

Feature Extraction: Specialised software is used to identify and extract the linear feature from the collected data. This often involves identifying road edges, railway tracks, powerlines, or the centreline of a pipeline, for example.

Topographic Mapping: In addition to the linear feature, topographic information is generated to depict the terrain around the corridor. This includes elevation data and the mapping of natural and man-made features within the corridor’s influence.

Data Integration: The linear feature data and the topographic data are integrated to create a comprehensive corridor map, or digital twin. This digital twin can be used for design, maintenance, and monitoring purposes.

Hazard Analysis: Once the entire corridor is mapped and represented geospatially, further desktop analysis can take place utilising models and artificial intelligence tools to identify risks to your assets. For example, this could involve vegetation encroachment measurements, flood modelling, or identifying landslide risks.

Why use Corridor Mapping?

Precise Route Planning

Our corridor mapping services provide the foundation for precise route planning. We capture the terrain, obstacles, and environmental factors with remarkable accuracy, allowing you to optimize your corridor layout and minimize potential issues during construction.

Swift Data Collection

Time is of the essence in any infrastructure project, and we understand that. Our technology enables rapid data collection, covering vast stretches of your corridor quickly and efficiently. You get the data you need in a fraction of the time it would take with traditional methods.

Detailed 3D Models

We don’t just capture images; we create detailed 3D models of your corridor. This means you can visualize the project from every angle, spot potential challenges, and ensure your design aligns with your vision.

Reduced Risks and Costs

By using our corridor mapping services, you reduce risks associated with unforeseen obstacles or errors in planning. This translates to cost savings as you avoid costly rework, design adjustments, and delays

Seamless Integration

Our services seamlessly integrate with your existing project workflows. Whether it’s for road design, pipeline routing, or railway development, we ensure our data and models work seamlessly with your existing software and processes

Environmental Impact Assessment

Corridor mapping isn’t just about construction; it’s also about minimizing environmental impact. Our services help you assess and mitigate potential ecological risks, ensuring sustainable corridor development
