Generates commune polygon, line and point layers for a Sequoia project.

This function is a convenience wrapper around get_com_poly(), get_com_line() and get_com_point(), allowing the user to retrieve administrative boundary products and automatically write them to the project directory using seq_write().

Usage

seq_com(dirname = ".", verbose = TRUE, overwrite = FALSE)

Arguments

dirname

character Path to the project directory. Defaults to the current working directory.

verbose

logical If TRUE, display messages.

overwrite

logical If TRUE, file is overwritten.

Value

A named list of file paths written by seq_write(), one per commune layer.

Details

Both topological (full extent) and graphical (restricted extent) representations are generated when relevant.

Commune layers are built from BDTOPO commune boundaries intersecting the project area defined by the PARCA polygon.

The following layers are produced:

Topological layers

Full commune geometry (polygon, boundary lines, centroids)

Graphical layers

Line and point representations clipped to a reduced convex buffer around the project area, intended for cartographic display

Each layer is always written to disk using seq_write(), even when it contains no features (nrow == 0).

Informational messages are displayed to indicate whether a layer contains features or is empty.
