defmodule Microwaveprop.Workers.StationElevationWorker do
|
|
@moduledoc """
|
|
Oban worker that enriches a `FixedStation` row with its SRTM
|
|
elevation. Enqueued from `Microwaveprop.Rover.create_station/2`
|
|
whenever the user-supplied attrs leave `elevation_m` nil.
|
|
|
|
A missing tile or a void value is non-fatal — the row simply stays
|
|
with `elevation_m = nil`. The worker also no-ops if the station has
|
|
been deleted between enqueue and execution.
