Well, but how many joins would you need to show all those data in multiple countries?
There are a lot of trees added to OSM in European countries for example, not everyone needs to know that e.g. Berlin has tree data in this DB and Frankfurt in another one.
- maxerickson 10y agoThat's what I meant by hypothetical though. How many people are scrambling to build global tree viewers that would only include the sparse data you would get by importing all the publicly available data sets? The interest in such data is going to tend to be local or be forced to take into account the nature of the data collection (and thus benefit from directly accessing the curated source data). An example of the latter would be an academic analysis; to pull data from OSM, it would need to start by determining geographic areas with good coverage, or the results would be utterly meaningless.
- adrianN 10y agoI like to think of OSM as striving be as complete and as accurate as possible. So I believe every correct piece of data should be added.
- maxerickson 10y agoSure, but a hasty import of large amounts of data that no one is around to maintain it is at odds with accuracy.
- toomuchtodo 10y agoWhich is why we should be encouraging government agencies to use OSM as the canonical reference.
- maxerickson 10y agoIt's probably going to take more than encouragement. Namely, changes to open records laws to make it okay to work on data sets that are not strictly public domain.
- toomuchtodo 10y agoIs not all map data in the US not in the public domain, being works by the government?
- maxerickson 10y agoThe point is that a public employee subject to open records laws can't edit OSM because OSM isn't public domain. Here's an example. The National Park Service can't treat OSM as their canonical data store: https://www.nps.gov/npmap/blog/nps-plus-osm-equals-places-of-interest.html https://www.nps.gov/npmap/blog/nps-plus-osm-equals-places-of... People play blame-the-ODBL, but there's not really any epically strong arguments against adjusting the public records laws to be a little more flexible.
