GeoWeb’s history

• At the beginning, web didn’t exist…


GeoWeb’s history

• Then WebGIS appeared….


GeoWeb’s history

• Then Google Maps was launched…


But what was missing in order to have a GeoWeb?• The integration of its own geodata within

powerful application• Usability• Native support of GeoData by the web• The web as most used communication

channel (Desktop, Mobil)• Interoperability between the various web

ressources and services


The Web ?

HTML+ LINKSWEB


The GeoWeb ?

GeoWeb, like Lego bricks !

The GeoWeb is composed of several bricks… that can be used like we want ;-)

Some examples of GeoWeb: FoursquareFoursquare is a mobile application that makes cities easier to use and more

interesting to explore. It is a friend-finder, a social city guide and a game that challenges users to experience new things, and rewards them for doing so. Foursquare lets users "check in" to a place when they're there, tell friends where they are and track the history of where they've been and who they've been there with.

Formats in GeoWeb ?

• GML: Geographic Markup LanguageThe Geography Markup Language (GML) is the XML grammar defined by the

Open Geospatial Consortium (OGC) to express geographical features.• KML: Keyhole Markup Language

Keyhole Markup Language (KML) is an XML schema for expressing geographic annotation and visualization within Internet-based, two- dimensional maps and three-dimensional Earth browsers.

• GeoJSON: Geo JavaScript Object NotationGeoJSON is an open format for encoding a variety of geographic data

structures. It is so named because it is based on JSON (JavaScript Object Notation).

• GeoRSS: Geo Really Simple SyndicationGeoRSS is a method of describing and pinpointing the physical locations of

Internet content. Using GeoRSS, it is possible to search for Web sites or items based on relevant geographic locations. In addition, GeoRSS facilitates the immediate dissemination of RSS feeds to specific users based on event type and location.

Access to ressources : Geocoding

Geocoding is the process of finding associated geographic coordinates from other geographic data, such as street addresses, or zip codes

Answer

Map API

http://api.geo.admin.ch/swisssearch?lang=fr&query=1530


Access to ressources : APIAn application programming interface (API) is an interface

implemented by a software program that enables it to interact with other software. (see API Generator)

Access to ressources: KML…. KML is a data format, not a service.But KML has interesting properris like the chaining

used for example in Ground Overlays and Netzwerk Links.

This format allows the aggregation of ressources and services.

KML


Zugang zu den Ressourcen: KML Ground OverlaysGround overlays enable you to "drape" an image onto the

Earth's terrain. The <Icon> element contains the link to the .jpg file with the overlay image. Possibility to add a WMS.

KML


Zugang zu den Ressourcen: KML Network LinkA network link contains a <Link> element with an <href> (a hypertext

reference) that loads a file. The <href> can be a local file specification or an absolute URL.

The <href> in a link specifies the location of any of the following:* An image file used by icons in icon styles, ground overlays, and screen overlays* A model file used in the <Model> element* A KML or KMZ file loaded by a Network Link

KML


Zugang zu den Ressourcen: GeoRSSDataflows can be geolocalized.

How is it possible to use these bricks in Switzerland (part in

german)?


Geoinformationsgesetz GeoIG

Artikel 1 Zweck

Dieses Gesetz bezweckt, dass Geodaten über das Gebiet der Schweizerischen Eidgenossenschaft den Behörden von Bund, Kantonen und Gemeinden sowie der Wirtschaft, der Gesellschaft und der Wissenschaft für

eine breite Nutzung, nachhaltig, aktuell, rasch, einfach, in der erforderlichen Qualität und zu angemessenen Kosten zur Verfügung stehen.

Geoinformationsverordnung GeoIV

• Art 34: Darstellungsdienst• Art 34: Download-Dienste• Art 35: Dienste für Geometadaten• Art 36: Transformationsdienste• Art 36: Zugang zu den Geobasisdaten


Geoinformationsverordnung

Suchdienste: Internetdienst mit dem man Geodienste und Geodaten mit den entsprechenden Metainformationen finden kann;

Darstellungsdienste: Internetdienst mit dem Geodaten dargestellt werden. Der Dienst erlaubt es Geodaten visuell zu durchforsten und die entsprechenden Metadaten lassen sich einsehen;

Download-Dienste: Internetdienst, der einen direkten Zugriff auf eine Kopie von Geodaten erlaubt;

Transformationsdienste: Internetdienst, der es erlaubt Geodaten von einem Bezugssystem ins andere zu transformieren;

The next steps for swisstopo

• Mobile API• 3D viewer• 4D viewer


The World Wide Web, abbreviated as WWW and commonly known as the Web, is a system of interlinked hypertext documents accessed via the Internet.

The GeoWeb implies the merging of geographical (location based) information with the abstract information that currently dominates the Internet


Thanks for your attention !
