There are some mapped locations for my gateway that are absolutely impossible and thus distoring the mapped area.
Is is it possible to delete this points? Probably I can’t do this by my own but how can ?
Move your gateway a hundred meters down the road - which will cause TTNMapper to treat it as a new one.
Ok, but it is not possible to delete just one or two records right ?
Yeah, sure, you could ask the maintainer to dig in to the database to delete a few records.
Or you could follow his instructions on the site and just tell the world your gateway is 100m down the road …
