A map showing pictures associated to retrieved features

Photo linking is a brand new technique consisting in creating links between OSM features and external pictures. The goal of this is to make OSM data illustrated and sourced by recent pictures.

Rationale

In order to make more user-friendly maps, it is interesting to illustrate our rich point of interest database with pictures, as other map providers already do. By populating the database with this kind of links, we allow developers to create easily visual maps for everyone.

It matters to make the links explicit, because it allows to choose a good picture between a set of available pictures, and also make sure that the feature to illustrate is well visible on it. It could not be done properly only using nearest, more recent picture, as it could be blurry, not in the right direction, and so on.

Mapping

Creating a link between an object and its picture in OSM is easy: just add the tag according to your picture source on the given object. See below to find how to associate picture according to its source.

To find easily nice pictures to associate on given OpenStreetMap objects, you can have a look at Pic4Carto, which is a tool for making contributions using open-licensed pictures. If you browse area near your POI, you will eventually find good pictures of it.

Tools

Editors

You can use any OpenStreetMap editor to add pictures tags on objects. However, there are a few dedicated editors to do so.

  • Flickr4OSM - Link your personal Flickr pictures to OSM features.
  • Pic4Review - Easy editor to contribute using pictures, creates links between OSM and pictures.

Renderers

Some map renderers supports showing pictures associated to OSM features.
