Data Access
Human Impact Index data are freely accessible, and the code to generate them is fully open souce, because we support the transparency and reproducibility of Open Science. It also helps conservation.

Github
All HII calculations are based on a common task framework written in Python and making heavy use of the Earth Engine API. Each task is a separate Git repository hosted under a GPL 3.0 license on GitHub, inheriting from a common set of classes Docker container maintained in task_base. READMEs and code is fully accessible at the link below.
Google Earth Engine
All Human Impact Index calculations are done within the task framework
referenced below, with Google Earth Engine at its core. Earth Engine is
a Cloud-based framework that combines a multi-petabyte catalog with a
powerful geospatial analysis API. HII outputs are stored in an
ImageCollection at projects/HII/v1/hii, one
image per date. Individual driver ImageCollections are also
available within projects/HII/v1/driver, named
infrastructure, land_use,
population_density, power,
railways, roads, and water.
Outside Google Earth Engine
For those without GEE access, HII assets are exported to a public bucket on Google Cloud Storage as Cloud-Optimized GeoTIFFs. These TIFFs can be loaded by url directly into QGIS, or downloaded for local manipulation.
HII TIFFS currently available:
Tiff files are over 3gb each.
