5.2.3.2 Open Street Map OSM

Open Street Map is a special candidate among the assessed platforms. OSM does not offer a public API comparable the other Social Media platforms. Still it provides up-to- date infrastructure data based on volunteered geographic information. Therefore OSM is a good candidate for inclusion into the overall scenario but should be treated differently e.g. as a basis for identifying escape routes.

Storyful was assessed as a promising candidate due to its features: Table 5 - Assessment of Storyful Criterion Availability Comment Public search API Available Filter by geolocation Available Filter by time and date Available Filter by keywordstags Available Amount of postings na Number of postings with geo information Not measurable, no official information available Pictures supported yes 12

5.2.3.5 YouTube

Though the number of YouTube videos featuring geolocation and near real time footage is increasing, the data supporting the defined scenario was very small. The integration was tested and performed prototypically within the Linked Data components described in section 5.7. In the future and also for other scenarios the amount of relevant data might grow. Thus the platform was assessed as promising.
