Compare grid cell counts

Usage

comp_trks(
  sim_trks,
  stations,
  land_barrier,
  vis_graph,
  multi.grid,
  HSgrid,
  snap_tolerance
)

sim_trks: Tracks to which modeled tracks should be compared
stations: A sf object comprised of receiver station locations with a buffer around them that represents the range of the receiver (polygons)
land_barrier: A sf polygon of a barrier object around which tracks should be re-routed
vis_graph: A visibility graph created from the barrier object @seealso pathroutr::prt_visgraph
multi.grid: boolean
HSgrid: When multi.grid = FALSE, a sf polygon grid; When multi.grid = TRUE, a list of sf polygon grids
snap_tolerance: The tolerance (in meters) at which an intersection between a station and a track should snap to the station centroid. It is recommended that the snap_tolerance be equal to the station buffer size.

A data frame with counts and differences by grid cell ID ("gid")
