STAC

STAC stands for SpatioTemporal Asset Catalog. It is a language to describe geospatial information, making it easier to work with, index, and discover. It is a standardised way to organise and access any kind of geospatial data, whether it's satellite imagery, drone footage, lidar, or bathymetry data.

Working with STAC catalogs in QGIS

STAC support in QGIS was implemented by Lutra Consulting. To use STAC in the QGIS browser you will need QGIS 3.40 (for basic funcionality) but preferrably 3.42 or later for filtering of STAC catalogs. At present the better-open-data STAC is not filterable so you'll be good with QGIS 3.40 or greater.

Adding a STAC connection

You can add a new STAC connection either through the Browser Panel or Data Source Manager:

• From the Browser Panel, right click on STAC and select New STAC Connection
• For the Name type better-open-data
• For URL type https://better-open-data.com/stac/catalog.json

As the data in the better-open-data STAC are Cloud Optimized format (COG), you can drag and drop items into QGIS canvas to view them. Enjoy!
