Talk:Microgrants/Microgrants 2020/Proposal/Map Maintenance with StreetComplete

My experience

Some thoughts. Before writing my endorsement I loaded and tested StreetComplete. It works very well. It asks one question about each point, not overwhelming users. Updating to the main servers was fast. Unfortunately it is sensitive to errors in the tagging - like it was looking for road names on private service road driveways incorrectly tagged as public roads. I needed a way to say "Map error" as a response. And on a big school site with many buildings it wanted to confirm that every building tagged 'school' was indeed a 'school'. Maybe the school should have been tagged as a relation with many child buildings, but I think relations are scary to our general users so I am not a big fan of requiring complex data structures. It also wants postal numbers where there are none. I live in Africa and postal numbers are often missing as there is no postal service - try to get food delivered in Nairobi - you have to describe your gate: "Black steel gate 2 gates from Dennis Pritt Road". Nice app! Craig.za (talk) 19:57, 16 May 2020 (UTC)

Thank you! The housenumber quest in particular has grown to be quite complex, because of regional differences and in order to reduce the amount of places where the app asks for a housenumber where in reality there is none. So far, the housenumber quest

1. is not shown at all in the Netherlands, Denmark, Norway, Czech Republic and Italy. Reasons vary (discussions are linked): Some are disabled because all addresses are imported from an official source, so crowd-mapping of housenumbers is discouraged. In the case of Italy, housenumbers are usually assigned to entrances to buildings or properties, not for houses but the app asks for the address of a house, so that is why it is disabled

2. the housenumber is only asked for buildings with no address that have neither an address node somewhere on their outline, within the building outline nor are in an area that has an address (such as a school)

3. It is possible to specify a house name instead of a house number because that is common in at least Ireland

4. For Japan and Slowakia in particular, a different input form is offered because they use a different addressing scheme than the rest of the world (block+house number in JP, conscription and optionally street numbers in Slowakia)

So, it is possible to make exceptions or adaptions for specific countries. Should the housenumber quest not be shown at all in South Africa in your opinion? --Westnordost (talk) 12:45, 17 May 2020 (UTC)

• "I needed a way to say "Map error" as a response." - have you found it? "other answers" + "can't say" should allow you to create an OSM note Mateusz Konieczny (talk) 14:03, 17 May 2020 (UTC)
