gmba_ids_from_points: Get mountain range IDs from points coordinates

In GMBA-biodiversity/gmbaR: A set of R functions to work with the GMBA Inventory v2.0

Get mountain range IDs from points coordinates

Description

Get GMBA Inventory v2.0 mountain range IDs based on xy point coordinates.

Usage

gmba_ids_from_points(xy_dataframe, range_selection = "basic", manual = NULL)

Arguments

xy_dataframe	A dataframe containing point coordinates, with columns "x" and "y" i.e. longitude and latitude
range_selection	Character string, the options are: "all" = all level ranges, cross-scale (attention: may need some processing time!) "basic" = basic mountain ranges only (default) "300" = ranges included in the 300 pre-selection "100" = ranges included in the 100 pre-selection "level1"-"level10" = ranges pertaining to the respective level of the inventory hierarchy "manual" = range IDs provided with manual
manual	Character string containing the IDs of manually selected mountain ranges. Only needed when range_selection is set to manual. Default is set to NULL

Value

The input xy_dataframe with an additional column "GMBA_V2_ID", containing the GMBA Inventory v2.0 mountain range IDs associated with the respective input point coordinate. In case a point coordinate is located in more than one mountain polygon (cross-scale), they are given as a collapsed character string, separated by comma. If a point coordinate does not lie within a mountain range polygon, an NA is returned

Examples

## Not run: 
rangeid_vector <- gmba_ids_from_points(xy, "300")
rangeid_vector <- gmba_ids_from_points(xy, "manual", c("11175", "10001"))
rangeid_vector <- gmba_ids_from_points(xy, "manual",
                                       gmba_ids_from_names(c("Black Forest", "European Alps")))
