Generate a Bounding Box from Coordinate Data

Source: R/order_planetscope_imagery.R
set_bbox.Rd

Creates a bounding box for a specified location based on a data frame of coordinates. The function filters the data for the given location, removes any rows with missing longitude or latitude values, and computes the minimum and maximum coordinate values. A buffer is applied to expand the bounding box by a specified distance (in degrees).

Usage

set_bbox(df_coordinates, siteoi, buffer = 5e-04)

Arguments

df_coordinates

A data frame containing coordinate data. Must include the columns site, lon, and lat.

siteoi

Character. The site identifier (i.e., the value in the site column) for which to generate the bounding box.

buffer

Numeric. A buffer distance (in degrees) to expand the bounding box in all four directions. Default is 0.0005.

Value

An object of class bbox (from the sf package) representing the bounding box for the specified location, or NULL if no valid coordinates are found.

Examples

if (FALSE) { # \dontrun{
df_coords <- data.frame(
  site = c("SiteA", "SiteA", "SiteB"),
  lon = c(-77.05, -77.00, -76.95),
  lat = c(38.80, 38.85, 38.90)
)
bbox <- set_bbox(df_coords, "SiteA", buffer = 0.001)
} # }
