Extraction, integration and exploration of crowdsourced geospatial content from multiple web sources

From Place-Memories to Active Citizenship: The Potential of Geotagged User-Generated Content for Memory Scholarship

“…The aggregation of images was achieved through the appropriation of a commercial data mining tool, Geostream (Lamprianidis and Pfoser 2014), with the capacity to gather online images with a selected geolocation. 4 Although the Geostream aggregator tool was originally developed to gather data from several different social media platforms, only some of these were image-based-the main image-sharing platform aggregated by Geostream was Flickr.…”

Advanced techniques and algorithms to collect, analyze and visualize spatiotemporal data from social media feeds

“…This allows us to demonstrate how the enabled social media platforms can all be accessed in a similar workflow, just by tweaking a set of parameters. The concept for the universal collector is used at an early stage in [53,54] and presented in more detail in Section 8.2.…”

“…Eventually the goal is that the resulting fused dataset and the computed metadata will be exposed via a single endpoint allowing other users and systems to use the combined information. This chapter's content is mostly based on the following two publications: [53] accepted in the 3rd ACM SIGSPATIAL International Workshop on Crowdsourced and Volunteered Geographic Information and [54] accepted in the 22nd ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems both held in parallel in 2014.…”
