Geospatial Intelligence in Public Health Policy and Disease Mapping in India
India’s public health system faces complex challenges due to its vast population, diverse geography, and uneven healthcare accessibility. The use of Geospatial Intelligence (GEOINT) has emerged as a crucial tool in disease surveillance, policy-making, and resource allocation. Technologies such as Geographic Information Systems (GIS), remote sensing, artificial intelligence (AI), and real-time data tracking applications have enabled health authorities to predict, monitor, and control disease outbreaks with greater efficiency.
Tracking Disease Trends in India
Geospatial intelligence has played a transformative role in tracking disease patterns and responding to outbreaks across India. The COVID-19 pandemic underscored the need for real-time disease surveillance, and GIS became central to India’s response. The Aarogya Setu mobile application, developed by the National Informatics Centre in collaboration with NITI Aayog, used GPS-based contact tracing and heatmaps to identify virus hotspots. At the same time, CoWIN, India’s vaccine management platform, integrated GIS to optimize vaccine distribution and track immunization coverage across different regions. The Bhuvan-COVID-19 platform, developed by ISRO’s National Remote Sensing Centre (NRSC), provided geospatial visualizations of case clusters, enabling targeted lockdowns and better healthcare resource management.
Beyond pandemics, geospatial intelligence has become a crucial tool in India’s vector-borne disease control programs. The National Vector Borne Disease Control Programme (NVBDCP) has incorporated GIS into its strategies for mapping malaria and dengue hotspots. With inputs from ISRO’s Cartosat and RISAT satellites, health officials can monitor stagnant water bodies—potential mosquito breeding grounds—and take preventive measures before an outbreak occurs. Municipal bodies such as the South Delhi Municipal Corporation (SDMC) have leveraged GIS-integrated mosquito surveillance programs, using satellite imagery and Google Earth Engine to locate high-risk zones and guide fumigation efforts. The Dengue Forecasting Model, developed by IIT Delhi in collaboration with the Indian Council of Medical Research (ICMR), utilizes GIS-based climate analytics to predict outbreaks based on rainfall, humidity, and temperature variations.
In tuberculosis control, geospatial intelligence has played a vital role in tracking patient movement, drug distribution, and high-burden districts under India’s National Tuberculosis Elimination Programme (NTEP). The Nikshay Portal, launched by the Ministry of Health and Family Welfare, integrates GIS-based monitoring tools to map TB cases, ensuring that diagnostic and treatment services reach vulnerable populations. This technology also helps analyze socioeconomic factors such as poverty, malnutrition, and access to healthcare facilities, which contribute to TB prevalence in India.
Technologies Driving Geospatial Intelligence in Public Health
India’s geospatial health infrastructure relies on a combination of GIS software, remote sensing technology, mobile health applications, and AI-powered analytics. Platforms such as ArcGIS, QGIS, and ISRO’s Bhuvan enable policymakers to visualize disease spread and plan interventions. The Bhuvan Health GIS module, in particular, integrates satellite imagery with ground-collected data to track communicable disease trends and healthcare accessibility.
Remote sensing plays a crucial role in environmental disease mapping, with ISRO’s Cartosat, INSAT, and RISAT satellites providing data on urban heat islands, stagnant water bodies, and air pollution levels. This information is essential for predicting outbreaks of vector-borne diseases, respiratory illnesses, and heatstroke.
Mobile health applications have further enhanced disease surveillance by enabling real-time data collection and patient monitoring. Platforms such as eSanjeevani, India’s national telemedicine portal, utilize GIS-based spatial analytics to connect doctors with patients in remote areas. The mDiabetes initiative, a joint effort by the WHO and AIIMS, integrates GIS data to track diabetes prevalence and educate at-risk populations. The Swasthya Bharat mobile application maps healthcare accessibility in rural regions, helping policymakers allocate resources effectively.
Artificial intelligence and big data analytics have strengthened geospatial health intelligence by enabling predictive modeling. The Integrated Health Information Platform (IHIP), developed by the National Informatics Centre, uses AI-driven geospatial models to analyze trends, predict outbreaks, and support health decision-making. AI-based disease forecasting models, which were instrumental in tracking COVID-19 transmission patterns, are now being expanded for use in malaria, dengue, and tuberculosis monitoring.
Case Study: Geospatial Intelligence in the National Health Mission (NHM)
The National Health Mission (NHM) has been a key driver of geospatial intelligence in public health governance. One of its most significant applications is in maternal and child healthcare monitoring under the Reproductive, Maternal, Newborn, Child, and Adolescent Health (RMNCH+A) program. GIS-enabled health dashboards track maternal health indicators, vaccination coverage, and infant mortality rates, ensuring that interventions reach high-risk populations.
The Kayakalp Initiative, aimed at improving sanitation in hospitals, employs GIS-based heatmaps to track hygiene compliance in government health facilities. By mapping sanitation scores and linking them to disease prevalence data, health administrators can implement targeted hygiene improvement measures.
In immunization programs, GIS has played a pivotal role in ensuring universal vaccine coverage. The Mission Indradhanush program, which aims to vaccinate children in underserved regions, relies on geospatial mapping of vaccination centers and child demographics. By using spatial analytics, health officials can identify areas with low immunization rates and deploy mobile vaccination units accordingly.
Challenges in Implementing Geospatial Intelligence in Public Health
Despite its numerous benefits, the integration of geospatial intelligence in public health policy faces several challenges. Data privacy and security concerns remain a significant issue, particularly with the widespread use of location-based health tracking applications. While platforms like Aarogya Setu have proven effective in disease surveillance, they have also raised ethical questions regarding patient data confidentiality and government surveillance. India currently lacks a comprehensive health data protection law, making it essential to establish clear data governance frameworks for geospatial health intelligence.
Another major challenge is the integration of health data from multiple sources. India’s public health data is fragmented across various ministries, state health departments, and private healthcare providers, making real-time GIS implementation complex. The lack of standardized health data formats hinders seamless integration between platforms such as the Integrated Disease Surveillance Programme (IDSP), Integrated Health Information Platform (IHIP) , and CoWIN.
Regional disparities in GIS adoption also pose a challenge. While urban centers have advanced GIS infrastructure, many rural and tribal regions lack the digital resources needed for effective geospatial health monitoring. The shortage of trained GIS professionals in the public health sector further slows down adoption rates. Capacity-building initiatives, such as GIS training programs for health administrators and disaster response teams, will be crucial in bridging this gap.
The Future of Geospatial Intelligence in Public Health
The future of geospatial intelligence in Indian healthcare lies in the integration of AI-powered predictive analytics, cloud-based GIS platforms, and real-time data-sharing networks. The Ayushman Bharat Digital Mission (ABDM) aims to create a National Digital Health Ecosystem, where GIS-based tools will play a crucial role in enhancing disease surveillance, pandemic preparedness, and telemedicine accessibility.
Advancements in 5G technology will enable real-time health monitoring through wearable devices, providing geospatial insights into disease spread, hospital resource availability, and emergency response coordination. The adoption of blockchain technology for secure health data sharing will further enhance privacy protections and data integrity.
India’s commitment to digital health transformation ensures that geospatial intelligence will continue to play a pivotal role in strengthening disease monitoring, healthcare delivery, and public health policy. By investing in advanced geospatial infrastructure, AI-driven analytics, and interdisciplinary collaborations, India is well-positioned to build a resilient, data-driven healthcare system that can effectively tackle future health crises.
