Accessing Machine-Extracted Map Data: Improved Data Downloads
To help you speed and scale up mapping, all Mapillary imagery is analyzed with computer vision technology to detect objects in images and position them on the map as map features. This includes things like traffic signs (1,500 different classes), traffic lights, utility poles, lane markings, and many more.
This data is available through subscriptions—you choose your area of interest and the data types you’re interested in. Throughout the subscription period, you’ll also have access to all new data that becomes available in the area as new imagery is added, whether by you or the rest of our contributor network.
You can retrieve the data through our APIs or download it as a file through the organization dashboard on the Mapillary web app. We’ve just released some updates to the download feature, enabling you to better slice and dice the data you’re interested in, and get it in the file format that best suits your mapping or GIS tools.
The download feature is available in our web app. Go to your organization dashboard and choose the geographic shape you want the latest data from (if you don't yet have a subscription, you can order it there directly).
The first thing you’ll notice about the new downloads is that you can now choose which object classes you’d like to download. You can opt for whatever number of classes, just note that you can download up to three million items in one set—this is to speed up the time for preparing your download. Once your requested download has been prepared, you can immediately request another one with more object classes if you wish. We will send you an email notification once your download is ready and you can access it in your organization dashboard.
The second big improvement is that in addition to GeoJSON and shapefile formats, which have been available for a while, you can now also choose to get the data as a CSV file or an Esri file geodatabase. You can choose your preferred format right after you’ve selected the object classes you wish to include.
As before, all your requested downloads are visible as a list in the Downloads section on the dashboard for your shape. You can download each file as many times as you’d like. As an improvement, we’ve added a shortcut to request a new download for the same data types as you have in an existing download. Just click the “Plus” button next to a previous download, and the download request window will pop up with the same object classes pre-selected. You can still add or remove more classes, and choose whatever file type you prefer.
We hope these improvements make it faster and easier for you to download map data and bring it to your tools and workflows. If you’re new to the organization features we offer, take a look at this Getting Started Guide. To learn more about our machine-extracted map data, see our Data Licenses page. And as always, if you have any questions or need help, just send us an email.
