Mapillary is a service for sharing geotagged photos developed by Mapillary AB, located in Malmö, Sweden. Its creators want to represent the whole world (not only streets) with photos using crowdsourcing.

Background[edit]

Mapillary co-founders were Jan Erik Solem, Johan Gyllenspetz, Peter Neubauer and Yubin Kuang.[1][2]

The project started in September 2013,[3] with an iPhone app released in November 2013, followed by an Android app released in January 2014.[4]

Mapillary received $1.5 million in seed capital funding from a group of investors, led by Sequoia Capital in January 2015.[5] In March 2016, it raised $8M additional funding (Atomico, Sequoia, LDV Capital, and PlayFair) for expanded operations, including more computer vision talent and a San Francisco office.[6][7] In spring 2018, the company received $15M investment led by BMW i Ventures for a total estimated funding of $25M.[8]

Features[edit]

Mapillary offers different capturing modes including walking, riding (either a bike or car), or panorama. On 10 September 2014, Mapillary announced that they now support panoramas and photo spheres.[9]

As of May 2014, Mapillary had around 0.5 million photos[10] and by December 2014, it had over 5.5 million.[11] As of March 2015 it had 10 million photos,[12] and by June 11, 2015 Mapillary had over 20 million photos, and by August 9 over 30 million.[13] As of February 6, 2016 Mapillary had over 50 million photos. There is a live counter on the homepage of their website.

Mapillary hit 200 million photos on 5 October 2017, and 300 million on June 7, 2018.[14]

Major dataset contributions[edit]

In 2018, Mapillary acquired major image datasets from two state transportation departments: approximately 5 million images each contributed by the Vermont Department of Transportation[15] and the Arizona Department of Transportation.[16]

License[edit]

The images on Mapillary can be used under Creative Commons Attribution-ShareAlike 4.0 International License (CC-BY-SA).[17] There is special permission to derive data from the photos for contributing to OpenStreetMap[18] and Wikimedia Commons.[17] The GPX tracks can be used without restriction, and derived data can be used provided it is ODbL.[19]

The license was changed on 29 April 2014 from CC-BY-NC to CC-BY-SA.[20]

The application itself, however, is proprietary, unlike the similar service OpenStreetCam.

Mapillary eventually plans to generate revenue by licensing the data its users generate to companies.[4]

Research/datasets[edit]

In May 2017, Mapillary released an open source subset of its very large and ever-expanding crowdsourced image dataset, the Mapillary Vistas Dataset of 25,000 street-level images, with pixel-wise annotation, to help train autonomous vehicle AI system algorithms. With data from 190 countries, they touted it as "the world's largest, most diverse dataset for object recognition on street-level imagery" and offered it free for both academic and commercial researchers, but licensing is required for commercial product integration.[21]

Mapillary Blog[edit]

Back in January 1, 2014, Mapillary created their company blog which allows users to "share long-form content that [they] are passionate about" and relate to Mapillary. Typically, blog posts will share user stories about how they utilized the platform as an aid in experiments, discussions, studies, etc.…; however, the company itself also uses this platform to post updates about certain developments, and update the community via weekly, and annual reviews.[22]

Another feature Mapillary added to its interface revolves around creating a community leaderboard that tracks various statistics in varying time frames ranging from particular months to all-time. Mapillary maintains the all-time leaderboard on the home page of their application, while highlighting their monthly leaderboards on the Mapillary Blog. [23]

Mapillary Tasker (Beta)[edit]

In November 28, 2017, Mapillary released a beta tool known as the Mapillary Tasker. With Mapillary already being a collaborative platform that utilizes crowdsourcing to build out its vision, Mapillary Tasker only extends that idea. Mapillary Tasker "enables a task creator to tell other contributors where help is needed and what needs to be done." On the other hand, contributors can sort through the various tasks listed on the beta and work on whatever projects are interesting and feasible.[24]

The tasks can range from "completing coverage, making map edits based on images, and verifying object detection," and separated between capture, map edit, and verification tasks on the actual tool. As a side note, because the tool is currently in beta, users have to send requests to be reviewed by Mapillary administrators, rather than having the autonomy to post whatever task you want assistance with.[24]
