Run a processing algorithm on a live GeoLibre map — geolibre_run

geolibre_list_algorithms() reports the available tools with their parameters; geolibre_run_algorithm() runs one in the browser. Results arrive on input$id_result, and any output layers are added to the map.

Usage

geolibre_run_algorithm(proxy, algorithm, params = list(), request_id = NULL)

geolibre_list_algorithms(proxy, request_id = NULL)

Arguments

proxy: A GeoLibre proxy created by geolibre_proxy().
algorithm: The algorithm id, as reported by geolibre_list_algorithms().
params: Named list of algorithm parameters.
request_id: Optional id echoed back with the reply.

Value

The proxy, invisibly.

Examples

if (interactive() && requireNamespace("shiny", quietly = TRUE)) {
  proxy <- geolibre_proxy("map")
  geolibre_list_algorithms(proxy)
  geolibre_run_algorithm(proxy, "buffer", list(layerId = "abc", distance = 500))
}
