<div dir="ltr"><div>Just found an online publication by Prof. Mark Graham and Stefano De Sabbata from the Oxford Internet Institute, UK, about the quantity and quality of OSM. </div><div><br></div><div>The article shows three commented maps, one showing the content density, one counting the no. of edits, and one visualizing the content age. </div>
<div><br></div><div>From the conclusions: </div><div><br></div><div>"OSM will turn 10 years old in a few months, and combining the findings obtained from these three maps, it is evident how it is a very good geographical representation of the most developed countries, and their urban environment. OSM also provide large amount of information about non-rural areas, although these are not as up-to-date and detailed as urban areas.</div>
<div><br></div><div>The quantity and the quality of the data make OSM one of the most powerful and exciting open-source projects that the Internet has facilitated in recent years, along with Linux and Wikipedia. Nonetheless, there is still a lot of work to do, and the development of the project in its second decade will probably depend on it attracting new volunteers among the new Internet users in Africa, Asia, Latin America, and the Middle East. Finally, OSM will be influenced by the relationships with those many companies which are currently based their mapping services on it, as well as the future spread of open data policies."</div>
