Spatial property is almost a pervasive component in the big data environment because everything happening on the Earth happens somewhere. Spatial data can be grouped into raster or vector according to the methods used in representations. Web-based services facilitate the publication and use of spatial data legacies, and the crowdsourcing approaches enable people to be both contributors and users of spatial data. Semantic technologies further enable people to link and query the spatial data available on the Web, find patterns of interest, and to use them to tackle scientific and business issues.
