The project will visualize the largely invisible water resource that runs underneath the ground. The UP Cebu Center for Environmental Informatics (CENVI) has experience in data processing techniques for generating map visualizations of geospatial data from satellites and other sources. GRNDH2O.ph will utilize sensors for deployment to multiple monitoring wells across the study area. These wells have direct access to the underlying aquifer system; hence, extracting real-time data from these wells will provide vital information on the groundwater state of health. The sensor system will emerge from the Open Data Kit (ODK) platform for mobile devices, which allows for offline data acquisition. Mobile-based data collection will suit the Philippine urban setting because many wells are in areas where communication infrastructure is non-existent or has poor performance. The idea is to collect data from as many wells as possible, regardless of transport access and communication constraints. GRNDH2O.ph will create a map of the data to visualize, ideally in real-time, the changes that occur to the groundwater resource as a function of urban development and climate change. Although mathematical models that propose to relate these variables with the state of groundwater resources are available, the availability of timely data will significantly enhance the accuracy and predictive value of such models for decision-making purposes.
