GeoSocial Web Service Identifies and Maps Your Geolocated Tweets

GeoSocial Web Service Identifies and Maps Your Geolocated Tweets | TIG | Scoop.it

Have you ever wondered just how many of your tweets have been geolocated, either on purpose or by accident? An interesting effort indeed as I’m sure this is a much larger issue than what you may have first thought. There’s no doubt that many people are accidentally providing geopositioning in their tweets and may not even be aware that they have enabled GPS tags to be stored with their tweet.

Miguel Ángel Vargas's insight:

(cat) Interessant servei web que et permet identificar i localitzar sobre un mapa els teus tweets georeferenciats. Tant si ho fas conscient com si no, pot ser una descoberta observar des d'on i com es concentrem les teves piulades.

Eines online per a comparar mapes de diverses plataformes web | TIG | Scoop.it

Na internet encontramos uma ampla lista de serviços de mapas online. O mais popular deles, o que não significa que seja o mais confiável, é o Google Maps. Você sabia que existem ferramentas web, gratuitas, que nos permitem realizar comparações entre as diferentes plataformas? Isso pode ser de grande valia como ferramenta para fins educacionais ou como uma opção de pesquisa pessoal.

Studying real time human mobility triggered by social events though on-line networks - IFISC

Studying real time human mobility triggered by social events though on-line networks - IFISC | TIG | Scoop.it

A team of researchers on social networks analysis from the “Institute for Cross-disciplinary Physics and Complex Systems” IFISC have studied how the “Via Catalana” can be depicted using geolocated tweets. “Via Catalana” was a human chain scheduled for yesteraday, September 11, the Day of Catalonia.

Researchers downloaded tweets mentioning “viacatalana” or including the hashtag #viacatalana, totaling about 175.000. They then selected those tweets that were geolocated, about 1000 for each two-hour period, and plotted the results on a map. It is important to remark that the data is unbiased and no processing was done prior to plotting.

About Paperscape

About Paperscape | TIG | Scoop.it

Paperscape is a tool to visualise the arXiv, an open, online repository for scientific research papers. The Paperscape map currently includes all (non-withdrawn) papers from the arXiv and is updated daily. 

 

Each paper in the map is represented by a circle, with the area of the circle proportional to the number of citations that paper has. In laying out the map, an N-body algorithm is run to determine positions based on references between the papers. There are two “forces” involved in the N-body calculation: each paper is repelled from all other papers using an anti-gravity inverse-distance force, and each paper is attracted to all of its references using a spring modelled by Hooke’s law. We further demand that there is no overlap of the papers.

USA OpenData Implementation Guide

The White House developed Project Open Data (See project OpenData on github) – this collection of code, tools, and case studies – to help agencies adopt the Open Data Policy and unlock the potential of government data. Project Open Data will evolve over time as a community resource to facilitate broader adoption of open data practices in government. Anyone – government employees, contractors, developers, the general public – can view and contribute.

LiDAR Viewer with Oculus and Hydra

Third video in the Vrui + Oculus Rift series. This one is about navigating in large 3D models, where the viewer is not working from the outside in, but properly "immersed" in the model. Large-scale models require different navigation methods, which in turn require their own special user interfaces.

Derechos fundamentales afectados por la geolocalización - El Derecho

Derechos fundamentales afectados por la geolocalización - El Derecho | TIG | Scoop.it

Por Juan de Dios Meseguer González Abogado en ejercicio. Perito Judicial Informático. Conclusiones:"Nuestro consejo práctico, es que si queremos garantizar nuestra intimidad durante periodos de vacaciones o en otros momentos, tendremos que desactivar todos los servicios que el teléfono móvil ofrece: desactivar la opción del GPS, acceso a internet, desactivar la opción de los lugares visitados en las redes sociales, etc. De este modo, podremos seguir recibiendo llamadas, pero al menos, nuestra posición será más difícil ser precisada. Pero no nos engañemos, mientras el teléfono esté encendido, es un elemento de geoposicionamiento y localización para los servicios de telefonía. Otra forma, sería activar el “modo de vuelo”, que desactiva el teléfono y el acceso a internet, pero no podremos recibir llamadas telefónicas. Finalmente, quitar la batería al teléfono móvil, será el método más radical, pero seguro, para que no puedan efectuar un seguimiento de nuestro periodo vacacional."

Miguel Ángel Vargas's insight:

Interesante análisis jurídico acerca de los servicios de Geolocalización  y su afectación legal sobre uno de nuestros derechos fundamentales: la intimidad.

Quizás el contenido se escapa al alcance de la geografía, base legal profunda, pero aporta elementos para hacer una valoración acerca de lo que perdemos y ganamos cuando utilizamos y permitimos que un dispositivo localice y comparta nuestra ubicación. Interesantes conclusiones al final del artículo ¿Somos capaces de desconectar?

Antoni Barniol's curator insight, July 30, 2013 8:31 AM

Cada vez es más complicado el separar nuestra privacidad con el uso de las redes sociales. La geolocalización es un dato que aparece prácticamente en todas las redes sociales (en twitts, fotografías, facebook, instagram, foursquare, etc.), lo que la mayoría de la gente no sabe es que por defecto se codifica esta información 'dentro' con las coordenadas (x,y,z) del GPS. Se puede hacer un mapa de nuestro recorrido utilizando las redes sociales, ya hay distintas aplicaciones que permiten crear estos mapas.

Por ejemplo esta visualización espectacular de 3 billones de tweets en un mapa http://bit.ly/19Rv8rS o la aplicación de TripAdvisor http://on.fb.me/16goV5X para crear un mapa de las ciudades que has visitado autorizando a su aplicación para obtener la información de tu página en Facebook. Quizás no hay que ser radical apagando el móvil, pero sí al menos entender lo que el móvil está haciendo.

Miguel Ángel Vargas's comment, July 30, 2013 12:11 PM
Totalmente de acuerdo Antoni, quizás es necesario que el usuario entienda y conozca que hacen nuestros dispositivos cada vez que compartimos nuestra actividad. Creo que no somos conscientes de la información que aportamos, aunque también es cierto que posiblemente es proporcional a los servicios que recibimos. Superar y limitar la barrera existente entre la geolocalización y nuestra intimidad debe ser un reto para nuestro sector tecnológico.

PELAGIOS stands for 'Pelagios: Enable Linked Ancient Geodata In Open Systems' - its aim is to help introduce Linked Open Data goodness into online resources that refer to places in the historic past.

 

Pelagios is a collective of projects connected by a shared vision of a world - most eloquently described in Tom Elliott’s article ‘Digital Geography and Classics’ - in which the geography of the past is every bit as interconnected, interactive and interesting as the present.

3-Sweep: Extracting Editable Objects from a Single Photo, SIGGRAPH ASIA 2013

by Tao Chen · Zhe Zhu · Ariel Shamir · Shi-Min Hu · Daniel Cohen-Or

 

There was a time not long ago when digital image editing was something left to the experts. Then tools like iPhoto and Instagram came along and brought some of those capabilities to the masses. There’s still room for experts today, but for most of us, quick fixes and prepackaged effects are enough. These tools effectively democratized image editing. Tao Chen hopes that 3-Sweep, an incredible piece of software he created with a team of researchers from Tel Aviv University, can do the same for 3-D objects.
