Create universal spatial map with reliable terra plotting — create_spatial

Universal mapping function that works with any spatial data type using reliable terra and base R plotting. No complex dependencies required. Falls back gracefully when optional packages are unavailable.

Usage

create_spatial_map(
  spatial_data,
  fill_variable = NULL,
  coord_cols = c("lon", "lat"),
  region_boundary = NULL,
  map_type = "auto",
  color_scheme = "viridis",
  interactive = FALSE,
  title = NULL,
  point_size = 3,
  output_file = NULL,
  verbose = FALSE
)

Arguments

spatial_data: sf object, data.frame with coordinates, file path, or SpatRaster
fill_variable: Variable to use for fill/color (for vector data)
coord_cols: Coordinate column names if data.frame provided
region_boundary: Optional region boundary
map_type: Type of map: "points", "polygons", "raster", "auto"
color_scheme: Color scheme: "viridis", "plasma", "ndvi", "terrain", "categorical"
interactive: Create interactive map using leaflet (if available)
title: Map title
point_size: Size of points (for point data)
output_file: Optional output file path
verbose: Print progress messages

Value

ggplot2 object, leaflet map, or file path (depending on options)

Examples

if (FALSE) { # \dontrun{
# These examples require external data files not included with the package
# Simple point map
create_spatial_map(study_sites, fill_variable = "ndvi_mean")

# Raster map with region boundary
create_spatial_map(ndvi_raster, region_boundary = "Ohio",
                  color_scheme = "ndvi")

# Interactive map (if leaflet available)
create_spatial_map(counties, fill_variable = "population",
                  interactive = TRUE)
} # }
