Import the project in Rstudio
run the following line in the console to install necessary packages:
install.packages(c("slickR","shiny","leaflet","viridis","rgdal","rgl","curl","jsonlite"))
the folder luft.map and 3d.map contain 2 different shiny apps you can run from Rstudio
you probably have to manually tinker with load.R and cron_leaf.R to cache the map data, i have them running as cron scripts, but you can load the maps just as well from the shiny app
