The computer, first introduced 60 years ago, has represented perhaps the greatest change in how maps are made. The further combination of computers and communication technology changed how maps are distributed – and how they are used. Maps became more interactive and animated. The cloud, the nexus of computers and communication technology, is the most recent symbol of this change. While often simply defined as using the processing and storage capacity of data centres, the cloud is interpreted here as representing a workspace for the continued development of maps as a form of both analysis and communication. Examined are the development and formation of the cloud, the distribution of multi-scale pan-able (MSP) maps, and other related areas of cloud cartography.

OpenEventMap: A volunteered location-based service / Katereh Polous in Cartographica, vol 50 n° 4 (Winter 2015)  

Public [article]  inCartographica > vol 50 n° 4 (Winter 2015) . - pp 248 - 258 Titre : OpenEventMap: A volunteered location-based service Type de document : Article/Communication Auteurs : Katereh Polous, Auteur ; Jukka Mathias Krisp, Auteur ; Liqiu Meng, Auteur ; et al., Auteur Année de publication : 2015 Article en page(s) : pp 248 - 258 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] accès aux données localisées [Termes IGN] application web [Termes IGN] données localisées des bénévoles [Termes IGN] événement [Termes IGN] Java (langage de programmation) [Termes IGN] OpenStreetMap [Termes IGN] service fondé sur la position Résumé : (auteur) Our lives are affected by myriads of events happening daily all over the world. For efficient planning and management of complex systems composed of various components, understanding relationships between an event and the reactive behaviour of involved components is vital. Analysing these complex relations demands a spatiotemporal event-based model, in which the event plays a central role. In this article we develop a framework which provides the possibility of mapping and storing event-related information on the OpenStreetMap (OSM) platform by volunteers. The study is divided into two different phases: first, mapping the event elements by adding new attributes adequately designed to encode spatiotemporal and semantic event information; and, second, representing the event-related information on a map by developing a Web application, offering a volunteered location-based service. To facilitate the event-mapping procedure, a Java OpenStreetMap (JOSM) plug-in was developed for volunteers. The plug-in was developed based on the notion of an event to adequately store and manipulate the semantic information of events in the OSM structure. The tool was used by more than 100 volunteers in Munich for the years 2012 to 2014. In addition to manual collection of event-related information by volunteers, a crawling framework was also developed to automatically collect freely available event information from various Web pages on the Internet. The framework extracts the same event elements as the plug-in. But the framework crawls each Web page according to some pre-defined rules and follows a post-processing step, if necessary. The manually collected events along with the crawled event information are visualized in a Web application. The study revealed that adding the possibility of event-oriented mapping to OSM empowers volunteers to collect a higher level of information (event information) for city maps. This information can furthermore be used for strategy development and service planning by decision-makers.
