Web Mapping 2.0: the Neogeography of the Geoweb

casa.ucl.ac.uk, 2008

Web 2.0, specifically The Cloud, GeoWeb and Wikitecture are revolutionising the way in which we present, share and analyse geographic data. In this paper we outline and provide working examples a suite of tools which are detailed below, aimed at developing new applications ...

por la introducción de nuevas tecnologías en el aula, en el lugar de trabajo, en los sectores públicos y privados. La geografía ha sido siempre una disciplina que adopta y utiliza tecnologías para escribir, describir, analizar y predecir acerca de patrones y procesos espaciales. El mapa es una de tantas tecnologías que hemos utilizado en nuestras pesquisas geográficas. Otras son la cámara fotográfica, las imágenes de percepción remota, y ahora los sistemas SIG. Las tecnologías las empleamos para cartografiar paisajes, actividades, interacciones hombre/medio, regiones y sistemas a escalas locales y globales. Lo que está surgiendo en el mundo académico y en los mundos reales

The authors describe how we are harnessing the power of web 2.0 technologies to create new approaches to collecting, mapping, and sharing geocoded data. The authors begin with GMapCreator that lets users fashion new maps using Google Maps as a base. The authors then describe MapTube that enables users to archive maps and demonstrate how it can be used in a variety of contexts to share map information, to put existing maps into a form that can be shared, and to create new maps from the bottom-up using a combination of crowdcasting, crowdsourcing, and traditional broadcasting. The authors conclude by arguing that such tools are helping to define a neogeography that is essentially ‘‘mapping for the masses,’’ while noting that there are many issues of quality, accuracy, copyright, and trust that will influence the impact of these tools on map-based communication.

Web mapping and the use of geospatial information online have evolved rapidly over the past few decades. Almost everyone in the world uses mapping information, whether or not one realizes it. Almost every mobile phone now has location services and every event and object on the earth has a location. The use of this geospatial location data has expanded rapidly, thanks to the development of the Internet. Huge volumes of geospatial data are available and daily being captured online, and are used in web applications and maps for viewing, analysis, modeling and simulation. This paper reviews the developments of web mapping from the first static online map images to the current highly interactive, multi-sourced web mapping services that have been increasingly moved to cloud computing platforms. The whole environment of web mapping captures the integration and interaction between three components found online, namely, geospatial information, people and functionality. In this paper, the trends and interactions among these components are identified and reviewed in relation to the technology developments. The review then concludes by exploring some of the opportunities and directions.

Cartography can look back on a long history, but never before has it been as popular and ubiquitous as it is today. More maps are being produced and used than ever before. Ever more information is being made available, recorded and stored digitally – and maps are very much a part of the current exponential flood of data. This is caused partly by companies like Google, and by the companies that make satnav systems, or develop apps. Transforming such masses of data into visualizable information that one can derive knowledge from represents a new challenge. Central to this enterprise is the question of how, under current conditions, one might use Web 2.0 mapping services in a bottom-up and empowering way: to facilitate participation by the wider public in urban planning projects, to organize decentralized political protest initiatives, or to generate collective knowledge, for instance.

Since the World Wide Web (Web) became a medium to serve information, its impact on geographic information has been constantly growing. Today the evolution of the bi-directional Web 2.0 has created the phenomenon of User Generated Spatial Content. In this Thesis the focus is into analysing different aspects of this phenomenon from the perspective of a mapping agency and also developing methodologies for meeting the challenges revealed. In this context two empirical studies are conducted. The first examines the spatial dimension of the popular Web 2.0 photo-sharing websites like Flickr, Panoramio, Picasa Web and Geograph, mainly investigating whether such Web applications can serve as sources of spatial content. The findings show that only Web applications that urge users to interact directly with spatial entities can serve as universal sources of spatial content. The second study looks into data quality issues of the OpenStreetMap, a popular wiki-based Web mapping application. Here t...

Citizens are increasingly becoming an important source of geographic information, sometimes entering domains that had until recently been the exclusive realm of authoritative agencies. This activity has a very diverse character as it can, amongst other things, be active or passive, involve spatial or aspatial data and the data provided can be variable in terms of key attributes such as format, description and quality. Unsurprisingly, therefore, there are a variety of terms used to describe data arising from citizens. In this article, the expressions used to describe citizen sensing of geographic information are reviewed and their use over time explored, prior to categorizing them and highlighting key issues in the current state of the subject. The latter involved a review of 100 Internet sites with particular focus on their thematic topic, the nature of the data and issues such as incentives for contributors. This review suggests that most sites involve active rather than passive contribution, with citizens typically motivated by the desire to aid a worthy cause, often receiving little training. As such, this article provides a snapshot of the role of citizens in crowdsourcing geographic information and a guide to the current status of this rapidly emerging and evolving subject.

Mashups, composed of mixing different types of software and data, first appeared in 2004 and 'map mashups' quickly became the most popular forms of this software blending. This heralded a new kind of geography called 'Neogeography'in which non-expert users were able to exploit the power of maps without requiring the expertise traditionally associated, in the geographic world, with cartography and geographic information science, and, in computer science, with data structures and graphics programming.
