Create PF and SSPF object from UA for a Sequoia project

This function reads the UA polygon layer (v.seq.ua.poly) of a Sequoia project, aggregates surfaces at the parcelle and sous-parcelle level and writes four derived layers:

Usage

seq_parcels(dirname = ".", verbose = FALSE, overwrite = FALSE)

Arguments

dirname

character Directory where the matrice file is located. Defaults to the current working directory.

verbose

logical If TRUE, display messages.

overwrite

logical If TRUE, file is overwritten.

Value

A named list of six file paths, corresponding to the exported PF and SSPF polygon and line layers.

Details

Created layers are automatically written to the project directory using seq_write(), respecting the dirname, overwrite, and verbose parameters.

The function performs two levels of spatial aggregation ande create 4 layers:

1. PF (Parcelle) Rows of the UA are grouped using the parcelle field, and corrected surface areas are summed. A polygon and border lines layer are created.

2. SSPF (Sous-parcelle) Rows of the UA are grouped using the parcelle and sous-parcelle field, and corrected surface areas are summed. A polygon and border lines layer are created.
