• highest_concentration() now uses focal calculations instead of geohashes to calculate the sum per cell
  • plot_points() now uses mapview::mapview() to plot the map
  • plot_points() now returns a warning when a specific provider tile is not available
  • neighborhood_gh_search() now returns a more precise outcome when the radius of the circle is not equal to 200m
  • sf::st_crs() is used for sf objects to not show the message that old crs is detected anymore
  • highest_concentration() now returns correct highest concentration when the circle of the highest concentration overlaps more than one geohash
  • plot.concentration() now handles many lon/lat pairs better
  • highest_concentration() is added to do a fast search for the coordinates of the highest concentration
  • neighborhood_gh_search() is added to look for even higher concentrations in the neighborhood of the coordinates found by highest_concentration()
  • points_to_polygon() is updated to keep spatialrisk and a new version of dplyr working together smoothly.
  • interpolate_krige() and interpolate_spline() are added for interpolation and smoothing on the sphere.
  • In concentration() the algorithm for testing if a point is inside a circle is updated by testing whether the point is inside a square diamond inside the square.
  • NEWS.md is added to track changes to the package.
