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.

ICT for Agriculture Entebe, Uganda

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

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 production


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
