openairmaps package is thoroughly documented in the openair book, which goes into great detail about its various functions. Functionality includes visualising UK AQ networks (
networkMap()), putting “polar directional markers” on maps (e.g.,
polarMap()) and overlaying HYSPLIT trajectories on maps (e.g.,
trajMap()), all using the leaflet package.
While an interactive map is preferred for exploratory directional analysis, it is limited to the HTML format. Some applications (for example, academic journals) demand “static” formats like .docx and .pdf. For this reason, “static” versions of openairmaps polar marker functions have been provided which are written in ggplot2. A benefit of being written in ggplot2 is that additional layers can be added (e.g.,
geom_label() could be used to label sites) and limited further customisation is available using
Static maps require users to provide a ggmap tileset, which at the time of writing requires an API key for either Google or Stadia Maps.
