What is SDI
• The spatial information infrastructure
addresses both technical and non-technical
issues, ranging from technical standards and
protocols, organisational issues, data policy
issues including data access policy and the
creation and maintenance of geographical
information for a wide range of themes.

Simply
• SDI include:
– Data
– Software
– People
– Policy

Why we need SDI
• Any management in agriculture, forestry,
environment protection, planning, etc.
depend on SDI
• SDI is important not only for public sector, but
also for private business

3 ways …
Public Administration
INSPIRE
Defined life-cycle (?)
Standards (OGC)
Administration, legislative …
Top-down initiative
Community
OSM, soc. networks
Unclear life-cycle
+/- Standards
Rich data sources
4th
Way ?
Portals
Google, Yahoo, …
Common internet user
Proprietary
Dependent on providers (data
ownership, licences…)

4th
WAY ?
GEOPORTAL
• Solution provided by CCSS and
WirelessInfo: interconnection of
information of public
administration, commercial sector
and social networks into one large
distributed network of information
and services. Intellectual Property
Rights to information and services
are preserved (provider can decide
to whom and how the data and the
services will be provided).
• INSPIRE compliant, exploitation of
open standards. Our “4th
WAY” is a
support for building of Single
Information Space in Europe for the
Environment (SISE) a Shared
Environmental Information Space”
(SEIS) .

Policy
• In Europe is defined SDI policy by INSPIRE
• World wide were ideas about UNSDI (now a
little sleeping)
• Promising is GEOSS initiative
http://www.earthobservations.org/
• This initiatives together with Open Geospatial
Consortium (OGC) could help defining
standards

Problem of policies
• Tunnel problem - building tunnels from two
sides
– Policy driven top down
– User driven Bottom up
• It is important to guarantee, that on the end
we will have only one tunel

The philosophy of 4th
way
• The philosophy of 4th Way 2 SDI is to offer:
• Free access to spatial information for everybody.
• Possibility to publish and share data for everybody
based on user‘s decision.
• Possibility to interconnect any portal based on
INSPIRE principles and OGC services with the
network of 4th way 2 SDI.
• Networked structured as Web. There is no hierarchy
of systems (pyramid)

OpenStreetMap
• OpenStreetMap (OSM) is a collaborative
project to create a free editable map of the
world.
• http://www.openstreetmap.org/

OpenStreetMap
• The maps are created using data from
portable GPS devices, aerial photography,
other free sources or simply from local
knowledge. Both rendered images and the
vector graphics are available for download
under a Creative Commons Attribution-
ShareAlike 2.0 licence.
• .

OpenStreetMap
• OpenStreetMap was inspired by sites such as
Wikipedia — the map display features a
prominent 'Edit' tab and a full revision history
is maintained. Registered users can upload
GPS track logs and edit the vector data using
the given editing tools.

History
• OpenStreetMap (OSM) was founded in July
2004 by Steve Coast. In April 2006, a
foundation was established with the aim of
encouraging the growth, development and
distribution of free geospatial data and
providing geospatial data for anybody to use
and share. In December 2006 Yahoo
confirmed that OpenStreetMap could use
their aerial photography as a backdrop for
map productionICT for Agriculture Entebe, Uganda

History
• By August 2008, shortly after the second The State of
the Map conference was held, there were over
50,000 registered contributors; by March 2009 there
were 100,000 and by the end of 2009 the figure was
nearly 200,000.Note that not all registered
contributors actually contribute to the map and that
as with other crowd sourced projects a minority of
individuals contributor the majority of the content -
in March 2008 some 10% of the registered user base
were contributing map data each month

Technology
• The initial map data was all built from scratch
by volunteers performing systematic ground
surveys using a handheld GPS unit and a
notebook or a voice recorder, data which was
then entered into the OpenStreetMap
database from a computer.

Technology
• More recently the availability of aerial
photography and other data sources from
commercial and government sources has
greatly increased the speed of this work and
has allowed land-use data to be collected
more accurately.

Technology
• When large datasets are available a technical
team will manage the conversion and import
of the data.

Licencing
• OpenStreetMap data is published under an open
content license, with the intention of promoting free
use and re-distribution of the data (both commercial
and non-commercial). The license used is currently
the Creative Commons Attribution-Share Alike 2.0
licence, however legal investigation work and
community consultation is under-way to re-license
the project under the Open Database License (ODbL)
from Open Data Commons (ODC) which is more
suitable for a map dataset

Integration of OSN into
applications

Our contribution
• GeoPortal for Everybody
– Open standard and Open Source based solution
for building local and regional SDI
– Offering of services for free data sharing
– Capacity building using educational portal or shara
data around the world

What is geoportal
• Geoportal is an interface that enables search,
portrayal, evaluation and sharing of spatial
and non-spatial data.
• Geoportal is a solution based on interoperable
standards (OGC, W3C, OASIS, ISO). Geoportal
is interconnected to other resources through
the Internet. It helps to create a distributed
structure of information and knowledge with
spatial position.

What is not geoportal
• Central data storage
• Closed web application with maps
• A solution that does not offer an open
interface and that creates one-way collection
space for spatial information (e.g. Google)
• A solution that does not support search of
data and information and their portrayal and
use by help of other resources (Geoportal can
be limited to paid outputs)

Architecture
• Independent components
• Composition according to user requirements
• Based on SOA
• Possibility to integrate with other resources
• Maximum openness
– Open Source
– Open Standards
• Extension to non-GIS community
– Open Search
– Administration of other (non-spatial) data sources

Components
• Metadata catalogue
• Visualization
• Data publishing
• Content management

Example

Connection with social networks
