Re: [OSM-talk] The real face of MAPS.ME edits and notes - a short analysis
Note: I'm replying to an old mail. If you don't have it. You can find it here: https://lists.openstreetmap.org/pipermail/talk/2017-June/078181.html "The real face of MAPS.ME edits and notes - a short analysis" >The price to reproduce all the on-the-ground mappers' > contributions we have is > likely to be somewhere between 4 million and 150 million euros: Hello, These monetary considerations could be valid so long as the MAPS.ME bad edits do not exceed a certain threshold. Past that threshold, maintainers can no longer keep up with the noise and the value of the map essentially drops to zero. Take a look at the Middle East, the map was filled with POIs such as "my house", "my uncle's house". For a map consumer, it would be a poor choice to use OpenStreetMap in these regions, because it's junk. They'd prefer Google Maps or Bing Maps. And so, OpenStreetMap becomes valueless, regardless of much money would have been invested in surveying, etc. I've deleted thousands of personal bookmarks in that area but I can no longer keep up and have no desire to continue doing so. The "my house" style tags will probably re-accumulate with time, reducing the value of the map. ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
[OSM-talk] The real face of MAPS.ME edits and notes - a short analysis
Much has been said about MAPS.ME note and edit functionality on this
list and elsewhere. I tried to get a real picture of how good/bad they
are. I went to mmwatch.osmz.ru and assessed 73 edits/notes made
between June 6th and 10th in Poland. Then I made a spreadsheet
(percentages at the bottom):
https://docs.google.com/spreadsheets/d/1LsSEOUnt0Yekv9aHPMW54M3BpPUpAwvZ1bVp9kaXTKw/edit?usp=sharing
Redundant name:xx: 18%
Address problem: 10%
Mistagging / name problem: 22%
Duplicate: 22%
Garbage: 8%
Personal bookmarks / data disclosure: 8%
No issues: 26% (only!)
It should be noted that many of these issues (at least the first two)
could be easily prevented in software. It's high time they get fixed.
I have a feeling that the only force preventing a catastrophe are
power users monitoring edits. Many address problems were fixed by
Zbigniew_Czernik ("daily address fixes after newbies"). He is a
prolific mapper since 2009. He recently told me that he's not keen on
devoting even more time to OSM, specifically because of noobs breaking
data (including addresses).
Given this, I'm actually interested in how things look in places
without any established local community. After all, MAPS.ME is popular
all around the world.
