Data

The first dataset is the Biodiversity Intactness Index(BII) Time Series. This data comes from the Microsoft Planetary Computer STAC catalog. In the analysis we use the 2017 and 2020 rasters. The catalog can be retrieved from the url https://planetarycomputer.microsoft.com/api/stac/v1

The second dataset is the Census Bureau County Subdivisions shapefile for Arizona. The Phoenix subdivision was downloaded from this shapefile. The data can be downloaded at https://www.census.gov/cgi-bin/geo/shapefiles/index.php?year=2024&layergroup=County+Subdivisions and was read in through the data folder.

An ESRI National Geographic style world basemap was used to show the Phoenix subdivision in its broader geographic context. The basemap was accessed using the contextily package.
