“…whether the user is a tourist) and the surroundings (the types of venues located around the user at a given moment) [30]. Also, the works of Boetcher and Lee or Kim et al present techniques for the detection of local clusters of activity around specific topics of interest [31,32]. This development in the GKD field, from an academic perspective, has happened in parallel with the development of the data-mining field in the application-driven environment of startups and technology corporations.…”

“…Currently, as the academic field matures, it is beginning to catch up with the technology side developed in the commercial world. The shift of focus towards real-time analysis [33] stresses the need to not only develop better algorithms but also develop them on top of a technological stack that allows the scaling up needed to solve the problems associated with real-or near-real-time analysis.…”

Trends in geospatial technologies have led to the development of new powerful analysis and representation techniques that involve processing of massive datasets, some unstructured, some acquired from ubiquitous sources, and some others from remotely located sensors of different kinds, all of which complement the structured information produced on a regular basis by governmental and international agencies. In this chapter, we provide both an extensive revision of such techniques and an insight of the applications of some of these techniques in various study cases in Mexico for various scales of analysis: from regional migration flows of highly qualified people at the country level and the spatio-temporal analysis of unstructured information in geotagged tweets for sentiment assessment, to more local applications of participatory cartography for policy definitions jointly between local authorities and citizens, and an automated method for three dimensional (3D) modelling and visualisation of forest inventorying with laser scanner technology.

“…Tweets with known location are also used by (Saravanan et al, 2013) and (Kim et al, 2013) for real-time information on the most relevant topics covered by users, by conducting a review of feelings indicating if a discussed topic is positive or negative. A methodology by which it is possible to discover the occurrence of a relevant event in a certain place, by collecting and analyzing geo-located tweets is proposed by (Kim et al, 2011).…”
