GeoWeb’s history
• At the beginning, web didn’t exist…
4Federal Office of Topography swisstopo Colloque 2010-2011, December 2010
GeoWeb’s history
• Then WebGIS appeared….
5Federal Office of Topography swisstopo Colloque 2010-2011, December 2010
GeoWeb’s history
• Then Google Maps was launched…
6Federal Office of Topography swisstopo Colloque 2010-2011, December 2010
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

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.

Answer
Map
21Federal Office of Topography swisstopo Colloque 2010-2011, December 2010
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
22Federal Office of Topography swisstopo Colloque 2010-2011, December 2010
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
24Federal Office of Topography swisstopo Colloque 2010-2011, December 2010
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
25Federal Office of Topography swisstopo Colloque 2010-2011, December 2010
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

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
30Federal Office of Topography swisstopo Colloque 2010-2011, December 2010
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 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
