FOSS4G-Asia 2023 Seoul

We created a REST API to register, search, and delete spatio-temporal data based on OGC API-Features, an international standard specification of the Open Geospatial Consortium (OGC), an international standardization organization for geospatial information, and the Moving Feature Encoding Extension-JSON (MF-JSON) specification, an international OGC standard specification developed mainly by AIST.
To create the API, we built an OGC-API server using pygeoapi and PyMEOS.PostgreSQL was used as the DB, and mobilityDB was used as an extension library for storing spatio-temporal data.For spatio-temporal data were stored using MobilityDB-specific type formats (TBool, TText, TInt, and TFloat).When converting MF-JSON for spatio-temporal data using PyMEOS functions, some tag names were not supported for conversion.Therefore, we implemented an additional process to convert the tag name to one that can be successfully registered before executing the PyMEOS function.
Also, at the time of this implementation, there were no source code modification guidelines for pygeoapi, so the API implementation was realized by directly modifying the source code of the lib directory that handles the API request processing.
