“In light of nationalist trends, disruptions to global food supply chains and efforts to concurrently promote sustainable diets, we assess national capacities to achieve dietary guidelines based on domestic production alone. Over a third of all countries cannot meet self-sufficiency for more than two of the seven essential food groups. Low self-sufficiency and overdependence on a few countries for imports threaten their capability to respond to global shocks, particularly for small states…”

Using Cloud Rasters with PostGIS | Crunchy Data Blog

Paul shows you how to access raster data stored in the cloud or object storage for PostGIS using cloud optimized GeoTIFF (aka COG) files. He also includes some functions for working with raster elevation.

Today, I discovered that Postgres materialized views do _not_ inherit their parent table's indexes. This is why my spatial query is still running after 24hours.. 9000 × 50,000,000 = 450 billion geometry comparisons. Doh!
