agb_ownership.R Takes in AGB and ownership GeoTIFF raster data and forest activity GeoJSON data. Produces conditional density plots for initial relationship examination, linear regression, and Random Forests models. Outputs mapdata.GeoJSON, which has ownership ("layer), activity, and change in AGB data ("delagb") for 30mx30m polygons in forests spanning from Arizona to New Mexico.
mapping.R Produces chloropleth plots from sf objects by reading in the geoJSON created by agb_ownership. These can be exported as images or PDFs.
index.html Supports summary webpage/user interface using edited Bootstrap Carousel example template. The site branch hosts the images and index file necessary to host the webpage on Github pages.
