Description for selectors for specific input types.

When specifying input types ‘country’, ‘countryRegion’, ‘countryRegionCRS’, ‘CRS’ or ‘bboxCRS’, selectors are automatically created that facilitate the selection of those inputs. After being selected, those inputs appear in the input.json of the script or pipeline as objects with various parameters that will be available when loading then in R, Python or Julia.

For example, the bboxCRS selector allows the user to specify a country, region and coordinate reference system to define a bounding box. The bounding box can also be selected manually, without first selecting a country or region. Here is an example of an object created through the selection of the Putumayo department in Colombia, in the Bogota 1975 / Colombia West zone reference system:

bbox:
  - 983337
  - 428305
  - 1360903
  - 659616
CRS:
  name: Bogota 1975 / Colombia West zone
  authority: EPSG
  code: 21896

Here is the meaning of each key.

Key name	Section	Description
bbox	bbox	Array containing the minimum x, minimum y, maximum x, maximum y coordinates (in that order) of the bounding box, in units of the selected CRS.
name	CRS	Plain text name of the coordinate reference system selected.
authority	CRS	Authority associated with the code of the reference system. Usually EPSG or ESRI. For example EPSG` for ‘EPSG:4326’.
code	CRS	Code associated with the authority of the reference system. Usually a 4 or 5 digit integer. For example 4326`for EPSG:4326
proj4Def	CRS	Proj4 string definition of the CRS.
wktDef	CRS	Well Known text definition of the CRS, when available.
unit	CRS	units associated with CRS. Usually meter, degree, or feet
CRSBboxWGS84	CRS	The bounding box covered by this coordinate reference system, in latitude, longitude, WGS84 (EPSG:4326)
englishName	country	English name of the selected country, according to GADM.org.
ISO3	country	3 letter ISO code for this
regionGID	region	Identifier of the region in GADM
countryEnglishName	region	English name of the country within which this region is.

When using other selectors, the object create contains a subset of the bboxCRS selector. For example, the countryRegion selector will only contain the country and region sections, and countryRegionCRS will contain all but the bbox section.
