Abstract

Access to potable water and sanitation remains one of the priorities of the UN 2030 Agenda, reflecting the urgent need for efficient monitoring of water resources in light of increasing environmental degradation and the growing demand for these resources. In this context, ORBTY has developed an innovative water quality monitoring system based on remote sensing, which combines satellite data, multispectral drone imagery, and advanced modeling. Unlike conventional approaches that rely exclusively on sporadic field sampling and laboratory analysis, ORBTY's technology provides continuous operational monitoring, ensuring frequent updates and broad geospatial coverage. The solution enables the identification of degradation trends, such as eutrophication, toxic algae proliferation, sediment load in reservoirs, and ecosystem responses to extreme climate events.In the third phase of PIPE, the project's objective is to prioritize the industrial and commercial development of the innovative technological solution built in PIPE Phase 2, aiming for its potential market insertion. Thus, the general objective is structured around three axes: (a) migration of the solution to the cloud, (b) enhancement of the data visualization interface, and (c) commercialization of the solution. The enhancement of the data visualization interface will be carried out through the migration of functionalities from ArcGIS and GEE APIs to the open-source Streamlit platform, providing a cost-free, high-performance alternative with a competitive market advantage.Finally, the migration of the geospatial monitoring solution for continental and coastal aquatic systems to the cloud will enable automated and scalable processing, storage, and display of water quality parameters, allowing the system to meet the growing demand from public and private sector clients in the fields of environmental monitoring, sanitation, aquaculture, and oceanography.
