Mapillary is a free travel and navigation application available on Android that allows users to capture street-level images of any place using their smartphone cameras. The app has a collaborative approach, combining all images into a navigable view of the world that can be used to improve maps, cities, and mobility. The program uses computer vision technology to provide a smooth viewing experience and speeds up mapping through machine-extracted map data.

With Mapillary, users can create their own street-level views by controlling when and where to capture the freshest imagery. The app's technology combines all images into a navigable view and blurs faces and license plates for privacy. Millions of images are added to the dataset every week, contributed by people, organizations, companies, and governments in 190 countries. The program integrates with tools like OpenStreetMap iD editor and JOSM, HERE Map Creator, and ArcGIS, allowing users to use the imagery and machine-extracted data to add details to maps and geospatial datasets.

Overall, Mapillary is an excellent tool for those looking to create and explore street-level views of the world, while also making a contribution to improving maps and mobility.
