GISCafe Weekly Review March 24th, 2018

Recently, ArcGIS Pro specialists at the company Mapillary answered a few questions for GISCafe Voice:

How long has Mapillary been in existence? What is its primary focus?

Mapillary is a street-level imagery platform powered by collaboration and computer vision. The company was founded in 2013.

Mapillary combines images from any device into a visualization of the world to generate data for improving maps, developing cities, and progressing the automotive industry. Mapillary’s tools enable anyone to collect, share, and use street-level images. Computer vision technology reconstructs locations in 3D and recognizes objects from the images to generate map data at scale. Today, people and organizations all over the world have contributed over 250 million images toward Mapillary’s mission of helping people understand the world’s places through images and making this data available.

What does the new Mapillary for ArcGIS Pro beta contain – what are its primary features?

The Beta focuses on bringing Mapillary public imagery into ArcGIS Pro. In short, it lets customers:

  • view Mapillary imagery as visual reference,
  • view, edit, and create features in street-level imagery,
  • compare imagery to see how places change over time.

What was in the previous release and why did you make certain feature upgrades?

The latest version, available in Public Beta, contains the same general functionality as earlier releases. However, we’ve made considerable performance improvements.

Earlier releases of Mapillary for ArcGIS Pro faced a challenge when rendering the large number of features required to show our imagery coverage. Our previous method of serializing vector tiles into a feature layer came coupled with a decrease in performance. For the Public Beta, we’ve notably increased performance and reduced system overhead by serving vector tiles directly into ArcGIS Pro. This means a faster and more efficient experience using Mapillary Imagery from the add-in.

Is a specific type of camera used?

The imagery on Mapillary is contributed collaboratively by Mapillary users all over the world: individuals, companies, non-profits, and governments. The platform is device-agnostic so every contributor uses a camera setup that suits them best, from Mapillary mobile apps to action cameras to professional 360-degree cameras.

What kind of geotagging of photos is used?

The Mapillary mobile apps (including integrations with some common action and 360-degree cameras) save location information into the image EXIF during capture and is then uploaded to Mapillary directly via the app. In addition, any geotagged images can be uploaded with help of our web uploader or command line tools. It’s also possible to upload image files together with a .gpx file that’s used for geotagging during the upload process.
