Location Based Services: Ensuring Digital Map Quality

Image 1: The OneAtlas Basemap, featured here, is a worldwide 1.5m layer made from our highest grade satellite imagery and is constantly refreshed. You can access it though an API, or download it into your own GIS.

Image 2: The OneAtlas Living Library is an online Earth observation satellite data service comprised of global data layers and fresh acquisitions of 50cm-resolution Pléiades and 1.5m SPOT imagery filtered for quality.

The background image displays the Living Library coverage over San Francisco. A subscription to the service allows users to zoom and pan the full resolution imagery, as well as stream or download the data to your GIS.

In the Living Library, Pléiades data has a maximum cloud cover of 15% with an incidence angle not exceeding 30 degrees. For SPOT, the parameters are 5% and 20 degrees.

New data is added daily, and subscribers will soon be able to request alerts when their Area of Interest (AOI) is covered with a new acquisition.

Technicians working on digital map databases can find their AOI in the Living Library to determine if recent imagery corrects or confirms reported errors in their own data sets.

Once notified of an error in their database, an online map developer can instantly access recently acquired Pléiades and SPOT (0.5m and 1.5m respectively) imagery of their AOI - no matter how small - from inside their mapping software environment to view and correct mistakes or inaccuracies related to the existence or location of new features.

There is fierce competition among online mapping services to ensure their users' experiences are accurate and up to date.
