Gateway to a successful start of Galileo: gate, Galileo test environment / S. Plum in Geoinformatics, vol 10 n° 8 (01/12/2007)

Public [article]  inGeoinformatics > vol 10 n° 8 (01/12/2007) . - pp 12 - 15 Titre : Gateway to a successful start of Galileo: gate, Galileo test environment Type de document : Article/Communication Auteurs : S. Plum, Auteur Année de publication : 2007 Article en page(s) : pp 12 - 15 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géodésie spatiale [Termes IGN] alpes orientales [Termes IGN] Bavière (Allemagne) [Termes IGN] Galileo [Termes IGN] positionnement par Galileo [Termes IGN] signal Galileo [Termes IGN] test de performance Résumé : (Editeur) GATE (Galileo Test Environment) is the only Galileo test and development environment worldwide where already today navigation is possible with realistic Galileo Signals on all frequencies in an outdoor area. Six transmissions stations deployed on top of six mountains in the German Alps, and two monitoring stations in the valley are the components making GATE a unique test environment. Receivers and applications being operated on the test ground receive the transmitted signals in such a way as if they were radiated from real Galileo satellites in the earth orbit. Thus, GATE enables an early development of technologies, receivers, applications and services, which will decisively influence the navigation market and so fosters the development in nearly all fields of Galileo products.

350 first order points selected: creation of a geodetic reference frame in WGS-84 datum for Cartosat in India / K.S. Rao in Geoinformatics, vol 10 n° 8 (01/12/2007)

Public [article]  inGeoinformatics > vol 10 n° 8 (01/12/2007) . - pp 16 - 20 Titre : 350 first order points selected: creation of a geodetic reference frame in WGS-84 datum for Cartosat in India Type de document : Article/Communication Auteurs : K.S.

Most of the triangulation network points established over high hills are either inaccessible or have been destroyed. The error is more than the Ground Control Point (GCP) accuracy required for the Cartosat-1 GCP library (GCPL), which rules out the usage of these Greater Triangulation Network points as reference points for the GCP library. This essentially requires the establishment of a reference frame in a suitable datum system.

Connecting the tangible and the virtual realm of a city: Wikicity / C. Ratti in Geoinformatics, vol 10 n° 8 (01/12/2007)

Public [article]  inGeoinformatics > vol 10 n° 8 (01/12/2007) . - pp 42 - 45 Titre : Connecting the tangible and the virtual realm of a city: Wikicity Type de document : Article/Communication Auteurs : C. Ratti, Auteur ; F. Calabrese, Auteur ; K. Kloeckl, Auteur Année de publication : 2007 Article en page(s) : pp 42 - 45 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Navigation et positionnement [Termes IGN] carte interactive [Termes IGN] cartographie par internet [Termes IGN] service fondé sur la position [Termes IGN] temps réel Résumé : (Editeur) In the past decades, real time control systems have been developed in a variety of engineering applications. In so doing, they have dramatically increased the efficiency of systems through energy savings, regulation of the dynamics, increased robustness and disturbance tolerance. Now: can you have a city that performs as a real time control system? This is the aim of the WikiCity project at MIT, which deals with the development of real-time location-sensitive tools for the city.

Gesticulation: agent-based simulation of complex spatial systems or how to put the real simcity into practice with the agent analyst extension for ArcGIS / F. Fischer in Geoinformatics, vol 10 n° 8 (01/12/2007)

Public [article]  inGeoinformatics > vol 10 n° 8 (01/12/2007) . - pp 56 - 58 Titre : Gesticulation: agent-based simulation of complex spatial systems or how to put the real simcity into practice with the agent analyst extension for ArcGIS Type de document : Article/Communication Auteurs : F. Fischer, Auteur Année de publication : 2007 Article en page(s) : pp 56 - 58 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Analyse spatiale [Termes IGN] analyse spatiale [Termes IGN] ArcGIS [Termes IGN] logiciel SIG [Termes IGN] Openmap [Termes IGN] simulation spatiale [Termes IGN] système complexe [Termes IGN] système multi-agents Résumé : (Editeur) Modeling all the individual entities in a spatial system is like building the system from its atoms. Multi-agent simulation offers many advantages for the exploration of social processes and gives researchers intuitive access to modeling. Although explicit spatial simulations are rare, spatial relationships often play an important role when considering processes within systems. Geosimulation seems to be the main paradigm of spatial simulation for the coming years. This article will explain the fundamentals of agent-based geosimulation and its advantages. It will also introduce Agent Analyst Extension, a tool for comfortably creating agent-based models in ArcGIS and OpenMap.

Standards in practice: part 5 geographic web services / Huibert-Jan Lekkerkerk in Geoinformatics, vol 10 n° 8 (01/12/2007)

The exchange of files is simple enough: attach them to an e-mail if they are small enough, or put them on the familiar CD-ROM or USB memory stick. The true ICT specialist will note that such methods of data transfer are rather old-fashioned. Nowadays we need immediate access to the most recent version of our data, preferably without having to use specific software.
