JOSM is a free software desktop editing tool for OpenStreetMap geodata created in Java, originally developed by Immanuel Scholz and currently maintained by Dirk Stöcker. The editing tool contains advanced features that are not present in OSM’s default online editor, iD.
QGIS is a geographic information system (GIS) software that is free and open-source. QGIS supports Windows, macOS, and Linux. It supports viewing, editing, printing, and analysis of geospatial data in a range of data formats. QGIS was previously also known as Quantum GIS.
Mapillary is a service for sharing crowdsourced geotagged photos, developed by remote company Mapillary AB, based in Malmö, Sweden. Mapillary was launched in 2013 and acquired by Meta Platforms in 2020. It offers street level imagery similar to Google Street View.
Ushahidi is an open source software application which utilises user-generated reports to collate and map data. It uses the concept of crowdsourcing serving as an initial model for what has been coined as “activist mapping” – the combination of social activism, citizen journalism and geographic information. Ushahidi allows local observers to submit reports using their mobile phones or the Internet, creating an archive of events with geographic and time-date information.
OSMTracker is an offline GPS tracker designed for collecting points of interest (POI) to be added to the map and for recording GPX tracks. POIs can be marked using shortcut buttons, voice, text, or by taking a picture. OSMTracker data is exported in GPX format with waypoints, making it suitable for import into the JOSM map editor.
OpenMapKit (OMK) is an extension of OpenDataKit allowing users to create professional quality mobile data collection surveys for field data collection. OpenMapKit launches directly from OpenDataKit when the OSM question type is enabled in a standard survey. Simply include OSM questions and tags in your survey to collect information on OSM in the field.
ODK is an open-source mobile data collection platform. It enables users to fill out forms offline and send form data to a server when a connection is found. Once on the server, the data can be viewed, downloaded, and acted upon. ODK is primarily used by organizations working in humanitarian aid and global development.
OsmAnd (OpenStreetMap Automated Navigation Directions) is a map and navigation app for Android and iOS. It uses the OpenStreetMap (OSM) map database for its primary displays, but is an independent app not endorsed by the OpenStreetMap Foundation. It is available in both free and paid versions; the latter unlocks the download limit for offline maps and provides access to Wikipedia points of interest (POIs) and their descriptions from within the app. Map data can be stored on the device for offline use. Using the device’s GPS capabilities, OsmAnd offers routing, with visual and voice guidance, for car, bike, and pedestrian. All of the main functionalities work both online and offline.
Maps.me is a mobile app for Android and iOS that provides offline maps using OpenStreetMap data. It was formerly known as MapsWithMe. In November 2014, it was acquired by Mail.Ru Group and became part of its My.com brand. In September 2015, the app was open sourced and a free and open-source software version was additionally made available on F-droid until the application was sold to the payment processor Daegu Limited, part of Parity.com, which changed the application user interface and content, which led Alexander Borsuk and Viktor Govako (original MapsWithMe founders) to release an open source ad- and tracker-free fork called ‘Organic Maps’ in response.
InaSAFE is free software that allows disaster managers to study realistic natural hazard impact scenarios for better planning, preparedness and response activities. InaSAFE is a plugin for QGIS.
OpenAerialMap is an open service that provides access to a growing collection of openly licensed imagery and map layer services. You can download or contribute imagery to this collection. OpenAerialMap creates a place for mappers to store and share their work with the rest of the community. Through this database, everyone has a go-to point to start helping out, whether it’s drone pilots in areas of crisis or mappers who want to trace from home. If you’re a provider of aerial imagery and would like to get involved, get started and contribute.
MapRoullete is a microtask platform and web application for OpenStreetMap. MapRoulette.org gives you small Tasks you can complete in under a minute to improve OpenStreetMap. Anyone can create groups of tasks, called Challenges, that the community can complete together. Tasks are divided into Challenges. A Challenge can be part of more than one Project. Each Project has its own management page where you can see Leaderboards and progress.
