I was wondering how FROST (SensorThingsApi) can be used with image/video/audio observation results. In particular I have a multispettral camera and a microphone mounted on a robot. The sensors produce respectively a set of images and a wav file on each oservation. |

Yes, generally large binary results are put in an external media server, and the Observation result contains a link to the data. The observation type OM_CategoryObservation is for cases where there is a set of valid values (an enum). In this case the most appropriate type would simply be OM_Observation. The STA-Plus best-practice also deals with image data, and analysis results of this data: https://docs.ogc.org/bp/21-068.pdf |
