Calculate Space Use Estimates from Track Data

Usage

calculate_space_use(
  track_data,
  by_fish = TRUE,
  by_time_period = FALSE,
  time_aggregation = "day",
  methods = c("convex_hull", "bounding_box", "mcp", "grid_cell_count", "95_ellipse",
    "constrained_convex_hull"),
  grid_resolution = 100,
  reference_raster = NULL,
  prob_column = NULL,
  prob_thresholds = NULL
)

Arguments

track_data: Data frame with fish tracks (columns: fish_id/path_id, datetime, x, y)
by_fish: Calculate separate estimates for each fish (default: TRUE)
by_time_period: Calculate estimates by time periods (default: FALSE)
time_aggregation: How to aggregate time: "hour", "day", "month", "none" (default: "day")
methods: Vector of methods to use (default: all available)
grid_resolution: Grid resolution for raster-based methods (default: 100m)
reference_raster: Optional raster object to use for grid-based methods

Value

List with space use estimates and summary statistics
