openstreetmap and inspire: can the twain meet?
DESCRIPTION
Talk given at FOSS4G Denver, Wed, 09/14/2011. See http://2011.foss4g.org/sessions/openstreetmap-and-inspire-can-twain-meet The INSPIRE directive (http://inspire.jrc.ec.europa.eu) aims to create a pan-European Union (EU), spatial data infrastructure to enable the sharing of spatial information across Europe. The directive requires that common specifications, based on OGC and ISO standards, are adopted by EU Member States. OpenStreetMap (OSM) is a free editable map of the whole world which is made by people like you. OpenStreetMap allows you to view, edit and use geographical data in a collaborative way from anywhere on Earth. (source: openstreetmap.org) At a higher level INSPIRE and OSM have some similar goals like creating and adopting a common set of geospatial standards and building an international SDI where maps and data are readily available for purposes like routing and disaster management. Both are aiming to remain vendor-neutral and free from proprietary mapping monopolies. But in many aspects INSPIRE and OSM are complete opposites: INSPIRE has a top-down, formal, legislative, "GIS-" approach, defined mainly by National Mapping and Cadastral Agencies (NMCAs). The "de jure" standards are verbose (GML), containing many "optionals". NMCAs have ample geodata. End-users are in the first place governments. OSM on the other hand has a bottom-up, informal, "Neogeographic" approach is defined by its users. Standards for geodata and network APIs are developed but in a more agile and organic fashion. Geodata is the main project artefact that is created by users but also through imports of available open datasets. Enduser is you. With mainly differences between OSM and INSPIRE we could just stop here, but that is not the purpose of this talk. My aim is to show where these projects can learn from each other and how they could collaborate and possibly integrate at the technical level. Several scenarios will be elaborated. Why ? Well, basically for the good and future of mankind !TRANSCRIPT
OpenStreetMap and INSPIRE:
Can the twain meet ?

““Oh, East is East, and West is West, Oh, East is East, and West is West, and never the twain shall meet”and never the twain shall meet”
Rudyard Kipling, The Ballad of East and West, 1889Rudyard Kipling, The Ballad of East and West, 1889
“Never the twain shall meet”
Two things which are so different as to have no opportunity to unite.
Twain derives from the Old English twegen, meaning two. The phrase “never the twain shall meet” was used by Rudyard Kipling, in The Ballad of East and West (1889):
"Oh, East is East, and West is West, and never the twain shall meet."
There, Kipling is supposedly lamenting the misunderstandings between the British and the inhabitants of the Indian subcontinent.

Quoting Kipling
Oh, East is East and West is West, and never the twain shall meet,
Till Earth and Sky stand presently at God's great Judgment Seat;
But there is neither East nor West, Border, nor Breed, nor Birth,
When two strong men stand face to face, though they come from the ends of the earth!
