[OSM-talk] Filling in the gaps in the map with crowdsourcing techniques

[Svavar Kjarrval]

Personally I prefer to take GPS tagged photographs when trying to
pinpoint something outside. However, this method doesn't (reliably) work
everywhere (e.g. in urban canyons). When the signal is too weak for a
GPS fix or non-existent, there are other methods to resort to. For
example specialised apps, maps.me, create an OSM note in OsmAnd, or
produce a rough drawing of the area; although I really try to avoid the
last one.

In your specific example, maps.me should be able to toggle the wifi
availability at specific POIs, including cafés.
