Open Location Code, OLC, generator & search on the OSM map

Posted by Alex-7 on 15 October 2018 in English (English).

The OLC is supposed to become a kind of global address system. It is especially interesting for regions with obsolete or nonexistent on-the-ground addresses.

I wrote a simple Open Location Code generator & search on the OSM map:

To generate an OLC code just click on the map at a certain location. The search box or an URL link are to be used to find a location for an OLC code. For example, here is the location of the Norfolk Island Central School stadium:

The Google map supports the OLC too via its search box.

One of the great advantages of an OLC address is that it can point to an exact location of an apartment or an office in a large building, what potentially can save a lot of time and fuel, for example, for a delivery service vehicle, and by this reduce the CO2 emission.

This Wikipedia article about the [Open Location Code] ( provides detailed information on how the open source OLC system was created and how it works.

Cool. There was a long discussion on the talk@ list in August (starting here) about importing OLC data into OSM (a bad idea) compared software support (like your site). There is a discussion about adding the search to the search bar, like your site, but I don’t think it’s been merged in yet…

rorym, thank you for your comment and for the information. There are several similar systems. What I like about the OLC is that it is open-source and that it is accepted by the Google maps.

Certainly, the computer maps are in competition. But the main problem is that a lot people do not use any maps at all.

Having one global standard, for instance the OLC, for addressing physical objects on the ground could lead to a wider adoption of maps by individuals and businesses. It could be beneficial for all.

Thank you for doing this, Alex.

Many of us has been looking forward to something similar within OpenStreetMap. Other mobile apps (OsmAnd, Maps.Me) already supports OLC, and a website to utilize like so, is an awesome way forward.
