EnglishWhat Is Mapillary and What Does It Offer?
Updated
Mapillary is a collaborative street-level imagery platform, now part of Meta, that hosts over 3 billion street-level images and the map data derived from them. It is useful if you want to explore street-level views of places worldwide, contribute your own imagery to fill coverage gaps, or pull map features into mapping, mobility, navigation, or autonomous-driving work. You can use any type of camera to capture images, and the platform uses computer vision to extract map features automatically.
What the platform provides
Mapillary combines three things: a global collection of street-level photos, tools to capture and upload more, and machine-generated map data built from those photos.
- Street-level imagery: More than 3 billion images covering roads and places around the world, kept current through contributions.
- Map data: Features extracted from imagery using computer vision, which can be used to update maps with detail that aerial imagery cannot show.
- Capture flexibility: You are not locked into one camera type; the platform lets you shoot with the camera you have.
- Open data: Imagery and map data are shared openly so that people working on city and road planning, mobility and navigation, and autonomous driving can make better-informed decisions.
How it works in practice
The workflow follows a simple loop:
- Capture street-level images with a camera as you move through an area.
- Upload them through the available apps or tools.
- Process the imagery, where computer vision extracts map features.
- Use the resulting imagery and data through the map explorer, downloads, or integrations.
A concrete example: if a road has a new sign or a changed lane layout that does not appear in aerial imagery, street-level photos of that road let you see and map the detail. The platform's automated feature extraction reduces the manual effort of turning those photos into usable map data.
Ways to access and use it
Mapillary offers several entry points depending on what you want to do:
| Need | What Mapillary offers |
|---|---|
| Browse imagery and map data | Map explorer |
| Capture and contribute | Mobile and desktop apps, command-line upload tool |
| Work within GIS | GIS solutions and ArcGIS integration |
| Build applications | Mapillary JS, image datasets, OpenSfM |
| Work with open map data | Open data resources, plus links to OpenStreetMap and HERE Map Creator |
| Get help or follow updates | Forum, help center, blog, release notes |
If you are a developer, the Mapillary JS library and image datasets are the natural starting points. If you work in GIS, the ArcGIS integration and GIS solutions are more relevant. If you mainly want to look at places, the map explorer is enough.
Who it is for
Mapillary suits several audiences: contributors who want to fill gaps in street-level coverage, mappers who need ground-level detail to update maps, developers building location-aware applications, and organizations working on mobility, navigation, or autonomous driving that rely on open map data. Because the data is open, it also supports research and planning work that benefits from shared street-level views.
Getting started
Start with the map explorer to see what coverage exists in an area you care about. If coverage is missing, download the app and capture imagery yourself. If you need the data for a project, look into the open data downloads and developer tools. The help center and forum are the places to resolve questions about uploading, processing, or using the data.
