What is open data?

A piece of data is open if anyone is free to use, reuse, and redistribute it subject only, at most, to the requirement to attribute and/or share-alike.No discrimination against Persons or Groups, or Fields of EndeavourThis approach brings at least public savings and allows a fair competition between companies, what strengthen economics.

OpenStreetMap is a web project aiming at creating a world map of the entire world, accessible free and downloadable for anyone. It has been started in 2004 by a student from UK.

www.osm.orgWhat is OpenStreetMap?

It is based on the joint action of thousands of contributors working voluntarily. Anyone can participate!

OSM focuses on all the visible, physical objects like: roads, buildings, land uses, facilities (health, education..) shops, industries, water and sanitation, natural spaces... but also not visible like administrative boundaries or transportation lines.

OSM does not store information about populations.1

www.osm.orgMapping any feature existing in the field, visible or not

Idea: A large number of individuals contributing together will tend to create high quality data.

Different kind of practises and tools strengthen this.

The analysis shows that, where OSM was collected by severalusers and benefited from some quality assurance, the qualityof the data is comparable and can be fit for many applications.The positional accuracy is about 6 metres, which is expectedfor the data collection methods that are used in OSM. Thecomparison of motorways shows about 80% overlap betweenOSM and Ordnance Survey .Quality: Muki Aklay (UCL) positional accuracy comparisons United Kingdom: OSM - Ordnance Survey Meridian II databaseHaiti: OSM - GoogleMapMaker MINUSTAH/CNIGS

OSM Data Structure

Based on the idea of key/value pairshighway=primaryname=I66building=yesaddress=123 Main Streetcity=Somewhereamenity=hospitalname=Sacred Heart

1How tags/attributes are defined?

If the tagging system is fully flexible, allowing anyone to create new keys/values, it is strongly recommended to use the already existing, debated, approved and described tags so that the OSM data remains consolidated as much as possible.

The OSM tags can be found on the wiki : http://wiki.openstreetmap.org/wiki/Map_Features

OpenStreetMap and humanitarian dataInterest for an open data, easily accessible for crisis response and quickly created by a numerous community of contributors started with the earthquake that hit Haiti on January 12, 2010.This major disaster affected the Capital City, Port-au-Prince, and the towns on its west side, causing maybe 200 000 casualties.

Within a few days, the response of the OSM community to map the affected areas has been intensive. https://www.youtube.com/watch?v=3XPvVcUNrjQ
