Real-Time Infrastructure Monitoring Using Satellites and Drones under PM Gati Shakti
India’s infrastructure expansion is increasingly defined by its scale, spatial spread, and inter-ministerial dependencies. With thousands of kilometres of highways, rail corridors, logistics hubs, pipelines, and urban infrastructure projects being implemented simultaneously, traditional monitoring mechanisms have struggled to provide timely and reliable oversight.
The PM Gati Shakti National Master Plan represents a structural shift in infrastructure governance by institutionalising geospatial technology as a core decision-making layer. Satellites, drones, and spatial analytics are now central to how infrastructure assets are planned, monitored, and coordinated across ministries and states.
Geospatial Technology as an Enabler of Integrated Infrastructure Governance
Geospatial technology enables infrastructure projects to be viewed not as isolated assets but as interconnected spatial systems. Under PM Gati Shakti, data layers from transport, power, urban development, environment, and logistics ministries are integrated on a common geospatial platform. This allows planners and executing agencies to visualise infrastructure projects in relation to land use, environmental constraints, existing utilities, and population centres. The result is improved coordination, reduced project conflicts, and faster approvals supported by spatial evidence rather than fragmented reports.
Satellite-Based Monitoring of National Infrastructure Projects
Earth Observation satellites provide continuous and large-area visibility essential for monitoring linear and distributed infrastructure. High-resolution optical satellite imagery is routinely used by central agencies to track construction progress of national highways, economic corridors, and freight routes. These datasets support time-series analysis that helps identify stalled segments, land acquisition bottlenecks, and alignment deviations across long project stretches.
Synthetic Aperture Radar imagery has gained particular importance for infrastructure monitoring in challenging environments. SAR data is used to assess ground deformation and subsidence risks along highways and railway corridors, especially in Himalayan states and flood-prone regions. This capability enables infrastructure agencies to detect early warning signs of structural stress and plan mitigation measures before damage escalates.
Drone Deployment in Highway Development and Monitoring
The National Highways Authority of India has institutionalised drone-based monitoring for highway construction and maintenance. Drones are deployed at regular intervals to generate high-resolution orthomosaics and digital elevation models for highway packages under construction. These datasets enable accurate verification of contractor progress claims, assessment of earthwork quantities, and identification of construction delays at specific chainages.
Drone surveys have been actively used for monitoring major expressway projects, where aerial data supports planning reviews, safety audits, and compliance checks. The ability to capture site conditions rapidly and repeatedly has significantly improved transparency and reduced dependence on manual inspections.
Geospatial Monitoring of the Delhi Mumbai Expressway Corridor
The Delhi Mumbai Expressway serves as a prominent example of geospatially enabled infrastructure monitoring. Satellite imagery has been used to track corridor-level progress across multiple states, while drone surveys provide detailed insights at interchanges, bridges, and complex engineering structures. These datasets support coordination between central agencies, state authorities, and contractors by offering a shared spatial view of construction status and land availability.
Geospatial monitoring has also been used to assess environmental compliance along the corridor, including alignment proximity to forest areas, water bodies, and settlements. This integrated spatial oversight has helped streamline decision-making and reduce execution delays.
Rail Infrastructure Mapping Using LiDAR and Drones
RailTel and Indian Railways have increasingly adopted drone-based LiDAR surveys for railway mapping and asset management. LiDAR data is used to create precise three-dimensional models of railway corridors, stations, and yards. These models support track modernisation, station redevelopment, and safety audits by providing accurate clearance and elevation information.
Drone-based surveys have also been deployed for monitoring ongoing railway infrastructure works, including track doubling and electrification projects. The ability to capture high-density spatial data has improved planning accuracy and reduced survey timelines compared to conventional ground-based methods.
Monitoring Rural Infrastructure and Water Supply Schemes
Geospatial technology is also being used to monitor rural infrastructure projects under national development programmes. Satellite imagery supports the tracking of road connectivity, habitation access, and land use changes in rural areas. In water supply initiatives, spatial data helps monitor the alignment of pipelines, location of storage facilities, and proximity to habitations.
Drone surveys are used at district and block levels to verify on-ground implementation and support progress reporting. These applications improve transparency and help ensure that infrastructure investments translate into tangible service delivery outcomes.
Integration with the PM Gati Shakti National Master Plan Platform
A defining feature of geospatial adoption under PM Gati Shakti is the integration of satellite and drone outputs into the National Master Plan platform. Infrastructure data from multiple ministries is visualised over standardised base maps, enabling planners to assess spatial overlaps and dependencies in real time. For example, highway alignments can be analysed alongside railway corridors, power transmission lines, and urban development zones to avoid conflicts and optimise routing.
This shared geospatial environment reduces silos and enables faster, evidence-based approvals across ministries and state governments.
Role of Artificial Intelligence and Cloud GIS
Artificial intelligence enhances infrastructure monitoring by automating the analysis of large geospatial datasets. AI-driven models are used to classify construction stages, detect land use changes, and identify anomalies in satellite and drone imagery. Cloud-based GIS platforms enable scalable data processing and secure sharing of spatial intelligence across agencies, ensuring that decision-makers have access to updated and reliable information.
These technologies collectively support predictive monitoring, allowing authorities to anticipate risks rather than respond after failures occur.
Benefits for Transparency, Efficiency, and Public Accountability
Real-time geospatial monitoring has significantly improved transparency in infrastructure development. Satellite change detection and drone imagery provide objective, verifiable evidence for audits, reviews, and dispute resolution. Early identification of delays and deviations reduces cost overruns and improves project delivery timelines.
From a governance perspective, geospatial monitoring enables oversight of thousands of projects without proportional increases in administrative manpower, making infrastructure governance more efficient and accountable.
Capacity Building and the Way Forward
While adoption has accelerated, challenges related to technical capacity, data standardisation, and institutional readiness remain. Strengthening geospatial skills at state and district levels is critical to ensuring consistent and informed use of satellite and drone data. Continued investment in training, standard operating procedures, and inter-agency collaboration will be essential to fully realise the benefits of geospatial infrastructure monitoring.
Conclusion
Real-time infrastructure monitoring using satellites and drones has become a cornerstone of India’s infrastructure governance framework under PM Gati Shakti. By embedding geospatial intelligence into planning, execution, and oversight, India is enabling more coordinated, transparent, and resilient infrastructure development. As geospatial technologies continue to mature, their strategic role in shaping efficient and future-ready infrastructure systems will only deepen.
