 The paper presents an approach for integrating geoprocessing components in the TAMIS WaterDam monitoring system using OGC Web Processing Service and Sensor Observation Service instances with lightweight REST APIs developed to ease integration with thin-web clients and other web-based components. This standards-based approach allows for easy integration of new processing facilities and observation data sources. This article was authored by C. Starsh, B. Pross, B. Grayler, and others.
