StreetComplete was designed by Tobias Zwick and launched in 2016 as a handy “low-bar entry” field capturing application for OpenStreetMap. In the following 2-3 years it rapidly rose to have a share of 3.9% of contributors favoured application, since it requires no real prior expertise in OpenStreetMap. The beauty of it is that it exploits the opportunity of a mapper being in situ where some features have been mapped, but lack details about their attributes, and tags on the OpenStreetMap database.
The UX is good, even for the experienced mapper it masterfully detects the absence {not to jump down a rabbit hole, but very like my favourite Pink Floyd Album } of tagging details, and then it supports the insertion of the correct tags with menu systems that are visual rather than everything being list driven. Perfect for being on the move, a car passenger or a leisurely walker. This is not supposed to be a review of the app, but you can probably detect that I am a fan.
With some help from my friend Amanda who downloaded the .pbf, and extracted all the editor traces of StreetComplete here I was able to get hold of a csv of all of the Ireland edits and then use that to make a heatmap, with some help from RustyB. The heatmap shows, what we would expect, greater use of the app in Ireland’s cities and large towns.
