https://video.osgeo.org/videos/watch/11c2c686-157e-49c7-a953-a608073d5e9f As the number of satelite program proposing large amounts of free raster data increases (Copernicus Sentinel, Landsat…), it becomes more and more interesting to store and access massive quantity of imagery data. Given the cost and the reliability needed to store such volumes of data, there is a strong interest to use cloud infrastructure. COG format (Cloud Optimized GeoTIFF) allows an efficient and reliable access to this data directly from any server supporting the HTTP 1.1 standard. As QGIS is the most spread OpenSource GIS, it is critical for this tool to support COG seamlessly. This presentation will explain the principles of the COG format. We will then describe, step by step, how to set it up on the OpenStack cloud platform. Finally, I will demo the configuration and visualization of this raster data directly from QGIS.
