Interactively Map NOAA CUDEM Tiles

Source: R/map_noaa_cudem.R
map_noaa_cudem.Rd

Generate an interactive map showing the geographic extent of all available NOAA CUDEM (Continuously Updated Digital Elevation Model) tiles. Optionally, users can specify a site location (lon, lat) and a radius (radius_m) to highlight relevant tiles near a point of interest.

Usage

map_noaa_cudem(lon = NULL, lat = NULL, radius_m = 10000)

Arguments

lon

Optional. A numeric value representing the longitude of the center point in decimal degrees (WGS84). If not provided, the full tile index is displayed without zooming or highlighting nearby tiles.

lat

Optional. A numeric value representing the latitude of the center point in decimal degrees (WGS84). Must be provided if lon is given.

radius_m

A numeric value specifying the radius in meters to search for CUDEM tiles around the center point. Defaults to 10,000. Ignored if lon and lat are not specified.

Value

Invisibly returns TRUE. The primary output is an interactive leaflet map printed to the viewer.

Examples

if (interactive()) {
  # Map showing only the full tile index
  map_noaa_cudem()

  # Map showing tiles near a specific location
  longitude <- -76.67
  latitude <- 34.72
  search_radius_meters <- 5000

  map_noaa_cudem(lon = longitude, lat = latitude, radius_m = search_radius_meters)
}
