Combine zone and closure area

Source: R/combine_zone.R
combine_zone.Rd

Creates a new spatial dataset that merges regulatory zones with closure areas.

Usage

combine_zone(spat, closure, grid.nm, closure.nm, recast = TRUE)

Arguments

spat

Spatial file containing regulatory zones.

closure

Closure file containing closure areas.

grid.nm

Character, column name containing grid ID.

closure.nm

Character, column name containing closure ID.

recast

Logical, if TRUE combined is passed to recast_multipoly.

Details

To combine zones with closure areas, this function performs the following steps:

  1. Create the union of the closure area

  2. Take the difference between the closure union and the zone file

  3. Take the intersection of zone and the closure union

  4. Combine the difference and intersection objects into one spatial dataframe

  5. Assign new zone IDs to intersecting polygons

The result is a single spatial dataset containing all polygons from both spat and closure with overlapping (intersecting) polygons receiving new IDs (see new_zone_id). This allows users to partially close regulatory zones during the model design stage.
