Operations Module#

The Operations module provides set operations for combining and manipulating GEOID sets, including union, intersection, difference, and symmetric difference.

Set Operations#

Union Operation#

Combines all GEOIDs from multiple sets:

GeoIDs.Operations.union_geoid_sets

source 
union_geoid_sets(set_names::Vector{String}, output_name::String, description::String="") -> Vector{String}

Create a new GEOID set that is the union of multiple existing sets.

Arguments

  • set_names::Vector{String}: Names of the sets to combine

  • output_name::String: Name of the new set to create

  • description::String: Optional description for the new set

Returns

  • Vector{String}: The GEOIDs in the new set

Example

combined = union_geoid_sets(["western_counties", "mountain_counties"], "western_mountain_counties")

Intersection Operation#

Keeps only GEOIDs that appear in all input sets:

GeoIDs.Operations.intersect_geoid_sets

source 
intersect_geoid_sets(set_names::Vector{String}, output_name::String, description::String="") -> Vector{String}

Create a new GEOID set that is the intersection of multiple existing sets.

Arguments

  • set_names::Vector{String}: Names of the sets to intersect

  • output_name::String: Name of the new set to create

  • description::String: Optional description for the new set

Returns

  • Vector{String}: The GEOIDs in the new set

Example

common = intersect_geoid_sets(["florida_counties", "coastal_counties"], "florida_coastal_counties")

Difference Operation#

Keeps GEOIDs from the first set that don't appear in the second set:

GeoIDs.Operations.difference_geoid_sets

source 
difference_geoid_sets(base_set::String, subtract_set::String, output_name::String, description::String="") -> Vector{String}

Create a new GEOID set that contains elements in baseset that are not in subtractset.

Arguments

  • base_set::String: Name of the base set

  • subtract_set::String: Name of the set to subtract

  • output_name::String: Name of the new set to create

  • description::String: Optional description for the new set

Returns

  • Vector{String}: The GEOIDs in the new set

Example

non_coastal_florida = difference_geoid_sets("florida_counties", "coastal_counties", "florida_inland_counties")

Symmetric Difference Operation#

Keeps GEOIDs that appear in exactly one of the two input sets (not in both):

GeoIDs.Operations.symmetric_difference_geoid_sets

source 
symmetric_difference_geoid_sets(set1::String, set2::String, output_name::String, description::String="") -> Vector{String}

Create a new GEOID set with elements that are in either set but not in both.

Arguments

  • set1::String: Name of the first set

  • set2::String: Name of the second set

  • output_name::String: Name of the new set to create

  • description::String: Optional description for the new set

Returns

  • Vector{String}: The GEOIDs in the new set

Example

exclusive_regions = symmetric_difference_geoid_sets("eastern_counties", "coastal_counties", "exclusive_regions")
