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

The GeoWeb ?

And/or MAP / Map API
And/or GeoRSS
And/or GeoTag
And/or KML/GML

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

Foursquare
Foursquare 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 Language
The 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 Notation
GeoJSON 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 Syndication
GeoRSS 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 API

Access to ressources :
API
An application programming interface (API) is an interface
implemented by a software program that enables it to
interact with other software. (see API Generator)

Map API

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 Overlays
Ground 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

KML Network Link
A 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

GeoRSS
Dataflows 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
