The last section discusses how two prototype applications were built based on the open geospatial architecture. Firstly, we demonstrated the interoperation of the Internet of disparate COVID-19 solutions and then contextualized them using open geospatial standards such as the OGC IndoorGML. Secondly, a new and unique geospatial algorithm was examined by building a person-to-place risk model for cleaning indoor spaces based on the colocation or co-movement patterns of people and places (e.g., a room) in an effective and interoperable way. For the visualization purpose of this research, the SensorUp Explorer developed by SensorUp Inc. was used and further developed as a spatiotemporal Web dashboard.
