A digital platform to support Citizen-Government interactions from Volunteered Geographic Information and Crowdsourcing in Mexico City

Rodrigo Tapia-McClung (2016)

This paper presents two case studies of volunteered geographic information processes in two different neighborhoods in Mexico City. Both cases deal with citizen empowerment and actions directed for the improvement of their local surroundings. They are constructed in a bottom-up fashion: from the citizens towards the local authorities. A digital platform was developed to support user-generated data collection for both cases; the second being an evolution of the first that incorporates several enhancements. The collection of enough citizen data is useful to focus efforts to negotiate with the authorities in detected regions and matters that need attention. Citizen-generated maps are useful communication tools to convey messages to the authorities, as the identification of these locations and situations provide a better picture of what, from the citizens’ perspective, is significantly deviated from the government’s point of view. The platform incorporates a way to validate official data, a voting strategy as a first approach to assess the credibility of citizen-contributed observations and crowdsourced information on parcel records.

Patterns of Internal Migration of Mexican Highly Qualified Population Through Network Analysis

Camilo Caudillo Rodrigo Tapia-McClung (2014)

Many real, social, technological, biological and information systems can be described as complex networks. Nonetheless, few studies treat migration from this standpoint. Some migration studies focus on people, and some others on places. The former require very detailed data, while the latter are based on aggregate data. This study is based on places and uses aggregate data, taking flows as an observable and their resulting patterns are the object of study. Mexican censual events take place every ten years, the most recent on 2010, and it has been only until recently that there are enough capabilities and tools available to visualize and model internal migration to the municipal level. Few studies have focused on analyzing migratory movements of such detail, opting instead for the state level. Network analysis allows the identification of communities with a certain degree of spatial structure, that is, the importance that geographical proximity plays in migration.



Variación espacial de la unión conyugal de los jóvenes en México


La unión conyugal es un eje organizador de la vida de las personas y de una sociedad. En México este evento es clave en el proceso de transición a la vida adulta. En muchos casos articula la salida del hogar y el inicio de la reproducción. Se sabe que en el ámbito nacional su temporalidad se ha postergado, pero poco se sabe sobre ella a nivel subnacional. En esta investigación se analiza la variación espacial de la proporción de jóvenes unidos conyugalmente. Se busca identificar la manera como influyen la desigualdad regional y la heterogeneidad cultural sobre la asunción de los roles adultos.



Geomatics Applications to Contemporary Social and Environmental Problems in Mexico

JOSE LUIS SILVAN CARDENAS Rodrigo Tapia-McClung Camilo Caudillo Pablo López Ramírez Oscar Sánchez Siordia Daniela Moctezuma (2016)

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 D modelling and visualisation of forest inventorying with laser scanner technology.

Las tendencias en las tecnologías geoespaciales han llevado al desarrollo de nuevas y poderosas técnicas de análisis y representación que implican el procesamiento de conjuntos de datos masivos, algunos no estructurados, algunos adquiridos de fuentes ubicuas y otros de sensores ubicados remotamente de diferentes tipos, todos los cuales complementan la información estructurada producidas regularmente por agencias gubernamentales e internacionales. En este capítulo, proporcionamos una revisión exhaustiva de tales técnicas y una idea de las aplicaciones de algunas de estas técnicas en varios casos de estudio en México para diversas escalas de análisis de flujos migratorios regionales de personas altamente calificadas a nivel de país y de la zona. -temporal de análisis de información no estructurada en tweets geoetiquetados para evaluación de sentimientos, a más aplicaciones locales de cartografía participativa para definiciones de políticas conjuntamente entre autoridades locales y ciudadanos, y un método automatizado para el modelado 3D tridimensional y visualización de inventarios forestales con tecnología de escáner láser.
