Shape files of GIFT regions

Get shapefile of GIFT regions for selected regions.

Usage

GIFT_shapes(
  entity_ID = NULL,
  api = "https://gift.uni-goettingen.de/api/extended/",
  GIFT_version = "latest"
)

Arguments

entity_ID: A vector defining the IDs of the regions.
api: character string defining from which API the data will be retrieved.
GIFT_version: character string defining the version of the GIFT database to use. The function retrieves by default the latest stable version. If set to beta, the most up-to-date version which is still subject to changes and edits is used.

Value

A spatial data.frame with 13 columns.

Details

Here is the detail of each column:

entity_ID - Identification number of the polygon
geo_entity - Name of the polygon
point_x - Longitude of the centroid of the polygon
point_y - Latitude of the centroid of the polygon
area - Area in km2 of the polygon
x_min - Minimum longitude of the polygon
x_max - Maximum longitude of the polygon
y_min - Minimum latitude of the polygon
y_max - Maximum latitude of the polygon
entity_class - Class of the polygon
entity_type - Type of the entity
polygon_source - Source of the polygon
geometry - Geometry column from sf
