The OpenStreetMap project, which began in 2004, will be the world's largest success as an open data project by participation of various companies and NGO organizations.

ODI says that "the contribution of particularly large companies is significant" about this success. For example, Microsoft imported images of buildings obtained from satellite photographs into OpenStreetMap, reflecting the shape of the building in the American map data. Apart from this, Apple also publishes data to reflect "building shape and height" in map data of France and Denmark, and Facebook uses ways to improve the quality of Thai map data using artificial intelligence I am considering it.

DigitalGlobe, which also performs measurement of artificial satellites, is also offering free use of satellite images stored by the company for use for improving the quality of OpenStreetMap. Telenav, which provides platform services such as connected cars and location information, has launched OpenStreetCam that collects street images, and the company reflects information such as stop signs and one-way traffic obtained from the collected images on OpenStreetMap We are seeking ways to make it.

ODI stated that "despite the fact that each of these large enterprises has enough funds and talent to create their own map service, they use OpenStreetMap to provide good service to many customers and users It is said. Owing to the contribution of these large enterprises, OpenStreetMap is likely to develop greatly in the future, "ODI wants companies and organizations who intend to start a new map business think about participating in OpenStreetMap". It is.
