Convert Lat/Lon Bounding Box to Web Mercator — convert_bbox_to_3857 • vantorr

Helper function to convert a bounding box or spatial object from EPSG:4326 (lat/lon) to EPSG:3857 (Web Mercator).

Usage

convert_bbox_to_3857(bbox_4326)

Arguments

bbox_4326: Numeric vector of length 4 (c(lon_min, lat_min, lon_max, lat_max)) or any spatial object supported by vantor_as_bbox().

Value

Numeric vector of length 4 with bounding box coordinates in EPSG:3857: c(x_min, y_min, x_max, y_max).

Examples

# Denver area in lat/lon
bbox_latlon <- c(-105.01, 39.72, -104.96, 39.75)
bbox_mercator <- convert_bbox_to_3857(bbox_latlon)
