Thanks for posting this here! I feel like this is mostly good constructive criticism.

I have given a few talks about using OSM data in the US government and it comes down to authoritative data sources and validation. It's a great starting point, but there needs to be another layer (or two) of validation before it can be used at the enterprise level. The National Map Corps has some good examples of how this can be implemented with data stewardship.

I am also working on a few projects to take public domain data and put it into OSM. While it's useful and mostly open, it's definitely less open than the original data sources. Another issues is that as soon as someone edits the imported data, it will become less authoritative as well.



> it will become less authoritative

Or better than the authoritative original.

Like with Wikipedia, where you often hear that people prefer to cite a single person as source (because "anyone could edit Wikipedia", as if no single person can setup a website or write a paper), at least Wikipedia has had thousands of reads and often dozens or hundreds of reviews. People are scared of the idea "it could be anyone", while the most likely editor is just a peer with good intentions.


In many (most?) cases it can be better than the authoritative sources. But there is also the possibility for vandalism or sloppy work.

There are established ways to combat this (peer review, data stewards, reputation scoring) and even OSM has a checkbox for further validation.

OSM will never fit every use case, but it's good to understand where it falls short and can improve.


You're welcome this Jimmy. And you rock. You're one of the people who got me into OSM in the first place.

And I still love OSM. I want to see it succeed!

Go Igles!


As soon as I started reading your article I actually started thinking of Jimmy and how he's been a part of a real government entity (the national park service) sending data directly into OSM.
