This analysis investigates the impacts of urban expansion by assessing the changes in the Biodiversity Intactness Index (BII) for Phoenix, AZ from 2017 to 2020.
Two datasets are used in this analysis:
1. Biodiversity Intactness Index (BII) Time Series
The 2017 and 2020 rasters were obtained from the io-biodiversity collection from the Microsoft Planetary Computer STAC catalog. The collection was filtered using the following bounding box: [-112.826843, 32.974108, -111.184387, 33.863574].
2. Phoenix Subdivision Shapefile:
The Phoenix subdivision shapefile was downloaded from the 2020 TIGER/Line® Shapefiles: County Subdivisions for Arizona, as provided by the US Census Bureau.
Phoenix subdivision data was housed in a data/ folder that was not pushed to the repository due to its size.
