May be but there's no need at all of OLC codes in the database itself. The OLC code is a rough rounding of actual coordinates, and coordinates are on all objets with much more precision. May be you can design a query application that allows you to enter an OLC code and zoom to it, or get the OSM

Agreed but in their complete absence OLC area codes can be a useful substitute. If you know how many coffee drinkers there are in a given OLC area code then you can decide if its worth opening up a coffee shop. Starbucks for example will do this sort of research before opening a new store and

Hi all, For anyone that would like to visualize that the Open Location Code grid looks like, I took some screen shots of it overlayed with some imagery. The smallest squares in the examples each have a 10 character OLC number/letter code. You will notice like every grid, the real world is not on

Except we don't hold the z coordinate in the OSM database. There are other addressing schemes such as three words but using the lat and long for the address is much simpler. Encoding it with OLC gives you the advantage of a more human friendly looking address. There are issues which have been

+ 1 with John Whelan Every place already has an "address" simply called latitude, longitude. The Open Location Code is simply another way of expressing that latitude, longitude. If some platform wants to provide an interface between OSM data to Open Location Code fine. But I don't expect

I think you have missed a major point. You do not give anyone an OLC. It is simply their lat and long encoded in letters. So every building in the world has a lat and long, it is its location. This can be expressed as an OLC. Cheerio John On Sat, 11 Aug 2018, 4:49 pm Blake Girardot, wrote:

Open Location Code or Plus code is just a method of representing latitude and longitude in a more human friendly way. It was originally created by Google but has been released under an open licence. It is possible to set osmand to show coordinates as OLC. This means it can display the OLC code
