The expected format is lon,lat per line where lines starting with characters will be ignored. You can create such a file manually via geojson.io -> Save as CSV. Optionally add a second line with

#BBOX:minLat,minLon,maxLat,maxLon

to specify an explicit bounding box. TODO: support GeoJSON instead.

Throws:

IOException
