IASO is an innovative, open-source, multilingual platform (available in English and French) designed for the comprehensive management of data collection, planning, monitoring, and evaluation of health, environmental, and social programs. Utilizing advanced geospatial capabilities, IASO facilitates structured geographic data management and optimizes field data collection by organizing efforts according to hierarchical levels. Its powerful data visualization tools enhance decision-making processes, making it particularly effective in remote areas thanks to its offline functionality. Key features of IASO include geo-enabled data collection with customized questionnaires based on XLS forms, georegistry for managing geographic data and hierarchies, microplanning for assigning data collection tasks to specific areas of interest, and the ability to record entities (individuals or items) alongside various workflows (e.g. health centre visits, delivery tracking, or other). It has been instrumental in updating geographic data in Democratic Republic of the Congo, Côte d’Ivoire, and Burkina Faso, where it also serves as the official georegistry. At the regional level, IASO supports the Global Polio Eradication Initiative in the AFRO region, providing robust geospatial and health facility registry capabilities. With its advanced geospatial features, IASO is a leading solution for geo-enabled campaign digitalization, enabling precise planning, monitoring, and execution of critical health interventions. Whether for vaccination campaigns (measles, polio, yellow fever, malaria etc.) or the distribution of essential health items (bed nets, seasonal malaria chemoprevention, etc.), IASO ensures efficient targeting and optimized resource allocation. More recently, IASO has been supporting the digitalization of a United Nations nutrition program for children under five, and pregnant and breastfeeding women, with plans for expansion to multiple countries. Its adaptability and scalability make it a powerful tool for tracking individuals and resources in various contexts, including monitoring community health workers and managing logistics. By providing real-time, high-quality data, IASO enhances decision-making, improves coordination, and ensures that interventions reach those who need them most.
