History tab: current vs new - local survey edits comparison over 1 year ago

@porjo: It is moving forward but there is still a long road to production. A lot of polishing is needed and also probably a new server for OWL is needed to handle production traffic.

OWL/History Tab Beta are back + UI feedback/ideas needed! over 1 year ago

@ikonor: Thanks for kind words, the current problem is that the UI is not keeping up with the backend/API so there is a lot of stuff that is possible (like showing better way history pages - geometry for each version + way "sub-versions" - when a node changes currently there is no new way version - OWL has that so you can track actual way history) but I haven't had the time to implement frontend.

I do no plan to work on OWL Viewer anymore - I have precious little time left as it is and I plan to spend it on bringing OWL on production and then adding new features based on OWL to the main site (osm.org) instead of working on separate/standalone applications.

@Tom: About the strange "artifact" you found above - it is caused by the fact that areas (landuse etc.) are now proper polygons in OWL database and are served by the API as such. But at the same time they are served in tiles so what you see in your link above is a tile with a landuse polygon which contains only the part of the landuse that actually changed. This looks strange, not sure how to solve it. I will check the Leaflet styling options to see if it's possible to distinguish polygons somehow (e.g. with a fill).

@Tom: Great suggestions, thanks. I will try to merge those somehow with what people have already suggested on Github.

About visualizing modified/deleted geometry - what exactly do you have in mind? Filtering out "insignificant" changes? Deleted geometry should already be shown although I see there's some kind of bug in the frontend that shows it as "previous geometry" so you have to hover the "back arrow" to display it. I will correct that.

Modified geometry is also shown - you can hover the "back arrow" to see previous geometry - this is kind of confusing UI-wise, suggestions welcome how to expose this feature better.

@craigloftus: Yeah, it should work (and works for me).

@Tom: Thanks for the report, I will take a look.

History tab: current vs new - local survey edits comparison over 1 year ago

Yeah, that's the challenge I'm trying to tackle with OWL and the new History tab. The technical problem is that it's not easy to track changes - all database schemas and, in general, data sources that we have are geared towards rendering and/or having only current data. That's not enough when you want to analyze changes - which by definition requires you to have the "before" state and the "after" state to calculate what's changed.

If you have any suggestions on how to improve the usefulness of this tool then please don't hesitate to create new issues on Github:

History tab: current vs new - local survey edits comparison over 1 year ago

@Tom: Exactly. One of the major features of OWL (the service that powers this new History tab) is that it tracks changes in geometry so it's possible to even show some nice animation on node/way/relation history page to show how given object has changed during its life.

Did you map it as a POI? :P
