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:

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 GeoNames.org.
ISO3	country	3 letter ISO code for this country.
code	country	2 letter code for this country
countryBboxWGS84	country	The bounding box covered by this country, in WGS84 (EPSG:4326), according to GeoNames.org
regionName	region	Name of the region, according to GeoNames.org
ISO3166_2	region	ISO code associated with this region, where available.
regionBboxWGS84	region	The bounding box covered by this region, in latitude, longitude, WGS84 (EPSG:4326), according to GeoNames.org
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.
