Vizionează videoclipul gratuit OSM 4UP: Four Years of Edits 2008-2011
Descrierea animaţiei:
Seeing the four years together illustrates how rapidly coverage has expanded. Europe saw a lot of edits in 2008, and activity has continued to increase steadily. Areas with little coverage in 2008 such as Latin America, Africa and especially Asia have seen dramatic increases in subsequent years, with growing mapping communities generating many more edits. In America, a bulk import of data (TIGER) dominated in 2008, while the following years show the growth of a vibrant mapping community.
