*Summary: *Volunteered Geographic Information (VGI) is becoming
increasingly important in a number of scientific and development domains,
and OpenStreetMap <https://www.openstreetmap.org/> (OSM) represents the
largest effort to date to harness the power of the internet for
crowd-sourced spatial data generation. OpenStreetMap was launched in 2004,
initially focusing on mapping the United Kingdom. At that time, Ordnance
Surveys and National Mapping Agencies developed roads datasets but did not
freely distribute them, and openly available roads data such as VMAP0 were
of poor quality. In April 2006, the OpenStreetMap Foundation was
established to encourage the growth, development and distribution of free
geospatial data and provide geospatial data for anybody to use and share.
OSM now has more than 2.3 million registered users, and has mapped more
than 34 million km of roads in all countries. From the early days there has
been a need to ensure the quality and accuracy of member contributions. In
his presentation, Mikel Maron will describe the evolution of approaches to
provide guidance to members and of applying QA/QC to the data set,
including recent work by MapBox <https://www.mapbox.com/>. In a second
portion, Paola Kim-Blanco will summarize the literature on independent
validation of OSM and describe CIESIN <http://www.ciesin.org/>’s efforts to
validate the data in low income countries.
