Bottom Line: Nevertheless, it still remains a challenge to discover the "right" information for the appropriate purpose.To achieve this we have developed and implemented a semantic geospatial data model by which a photograph can be enrich with geospatial metadata extracted from several geospatial data sources based on the raw low-level geo-metadata from a smartphone photograph.We present the details of our method and implementation for searching and querying the semantic geospatial metadata repository to enable a user or third party system to find the information they are looking for.

ABSTRACT
With the increasing abundance of technologies and smart devices, equipped with a multitude of sensors for sensing the environment around them, information creation and consumption has now become effortless. This, in particular, is the case for photographs with vast amounts being created and shared every day. For example, at the time of this writing, Instagram users upload 70 million photographs a day. Nevertheless, it still remains a challenge to discover the "right" information for the appropriate purpose. This paper describes an approach to create semantic geospatial metadata for photographs, which can facilitate photograph search and discovery. To achieve this we have developed and implemented a semantic geospatial data model by which a photograph can be enrich with geospatial metadata extracted from several geospatial data sources based on the raw low-level geo-metadata from a smartphone photograph. We present the details of our method and implementation for searching and querying the semantic geospatial metadata repository to enable a user or third party system to find the information they are looking for.

sensors-15-17470-f002: Snippet of RDF XML created for a photograph by MediaPlace. The 256 bit SHA hash has been abbreviated for improved presentation clarity.

Mentions: The semantic geospatial metadata of each photograph is generated by instantiating the ontological geospatial data model, which is assigned a unique id so that it can be identified. The id is a 256 bit Secure Hash Algorithm (SHA) hash generated from the latitude, longitude, and compass of the photograph. This ensures that every photograph will have its own unique id, however, it also ensures that the same photograph is not processed twice. In other words, the same place and direction, as the geospatial model for that location has already been computed. Figure 2 shows an example of the semantic geospatial metadata in RDF XML format created for a photograph.
