Source: R/draw_bb.R
draw_bb.Rd

Opens an interactive map interface in your web browser where you can draw a rectangular bounding box to select an area of interest. Use the rectangle tool in the top-right corner to draw the box, then click 'Submit' to return the selection.

Usage

draw_bb(start_place_name = NULL, terrain = TRUE, provider = NULL)

Arguments

start_place_name

Optional address or place name to initially center the map on. This helps you quickly navigate to your area of interest.

terrain

Logical, whether to use OpenTopoMap tiles (default: TRUE)

provider

Optional custom tile provider. If specified, overrides the terrain parameter. See leaflet::providers for available providers.

Value

A bounding box object (sf::bbox) that can be used with get_elevation()

Examples

if (FALSE) { # \dontrun{
# Open map centered on default location
bb <- draw_bb()

# Open map centered on a specific location
bb_innsbruck <- draw_bb("Innsbruck, Austria")

# Use the returned bounding box to get elevation data
elevation <- get_elevation(bb_innsbruck)
} # }
#
