Summary

We have released a new version of CARTO Spatial Features, including global urbanity, climatology, and elevation data, now available on the H3 grid. The dataset includes variables for urbanity level, elevation, and climatology, allowing users to model location-based context with greater detail. This release supports a new geographic support system, the H3 grid, which enables fast computation of distances between hexagons and neighboring areas. The global urbanity classification has been built synthesizing information regarding population density and urban infrastructure, and is now available as a new variable within the dataset. We have also included global digital elevation data from NASA's Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model, and climatology features based on monthly averages from the WorldClim database. The H3 grid supports sixteen resolutions, each composed of cells with one-seventh the area of the lower resolution containing cell. This new version of Spatial Features is available as a premium dataset in CARTO's Data Observatory, or as public datasets for the United States, United Kingdom, and Spain in the Quadgrid 15 and H3 formats.
