- Abstract summary: Massive imagery and text messages from open platforms and social media form a temporally quasi-seamless, spatially multi-perspective stream.
We address key aspects in the field, including data availability, analysis-ready data preparation and data management.
We present the first extensive discussion of ethical considerations of social media data in the context of geo-information harvesting and geographic applications.

- Abstract: As unconventional sources of geo-information, massive imagery and text
messages from open platforms and social media form a temporally quasi-seamless,
spatially multi-perspective stream, but with unknown and diverse quality. Due
to its complementarity to remote sensing data, geo-information from these
sources offers promising perspectives, but harvesting is not trivial due to its
data characteristics. In this article, we address key aspects in the field,
including data availability, analysis-ready data preparation and data
management, geo-information extraction from social media text messages and
images, and the fusion of social media and remote sensing data. We then
showcase some exemplary geographic applications. In addition, we present the
first extensive discussion of ethical considerations of social media data in
the context of geo-information harvesting and geographic applications. With
this effort, we wish to stimulate curiosity and lay the groundwork for
researchers who intend to explore social media data for geo-applications. We
encourage the community to join forces by sharing their code and data.
