OpenStreetMap (OSM) is an online map of the world that “creates and distributes free geographic data for the world” (http://wiki.openstreetmap.org/wiki/Main_Page). Since its early days, starting in 2004, its reach has quickly spread to the most remote areas of the globe – due to the development of web-mapping and the concept of crowdsourcing.
Crowdsourcing is when community participants volunteer their efforts by adding relatively small pieces into a shared, publicly available product. And despite its name, the OpenStreetMap contains street network data and other useful information, such as speed limits, points of interest, land features (rivers, lakes), and more. It is impressively accurate, especially in areas dense with contributors.
Check this out for yourself:
- Open the map and navigate to an area you know well. Is everything correct? Look at the road names, house numbers, land features and points of interest. If you notice something that doesn’t look correct, you can easily become an OSM contributor and fix the omissions.
- Whether you live or run a business in a densely populated area or some remote location, you can help yourself and others by contributing to provide free and equal access to high-quality maps and other geographical information.
Go ahead and try it. You will be glad you did (and others will too)!
