The state of the art of OpenStreetMap

technologies, community and research challenges


~http://www.openstreetmap.org

OpenStreetMap is a free editable map of the whole planet.

It is made by people like you.

Tools used to collect the data


Geometric Elements

Node

A node represents a specific point on the earth's surface defined by its latitude and longitude. Each node comprises at least an id number and a pair of coordinates.

Way

A way is an ordered list of between 2 and 2,000 nodes that define a polyline. Ways are used to represent linear features such as rivers and roads.

Ways can also represent the boundaries of areas (solid polygons) such as buildings or forests. In this case, the way's first and last node will be the same. This is called a "closed way"

Relation

A relation is a multi-purpose data structure that documents a relationship between two or more data elements (nodes, ways, and/or other relations).

[...]Through collaboration with the OpenStreetMap community, we believe we can enable greater transparency, deliver the best local experiences, and facilitate innovation at scale.[...]


mapping parties do cause anincreased editing activity during the events themselves; they also sustain engagement over time, though mostly for already active contributors;

however, they largely fail on theirthird goal of engaging new-comers.

And now we organize a Mapping Party!!!

OpenStreetMap and (citizen) Science

OpenStreetMap is a big laboratory

The OSM Wiki is a big repository of knowledge(gis, community, crowdsourcing, openness...)

Each place has different communities

Respect OpenStreetMap and you can obtain the best from the community

OpenStreetMap needs help from the scientist:- enable the trust on the project- detect mistakes / violations- increase the engagement (gamification)- enpower the tags
