Note: we didn't import anything in the main OSM db.  For this test we uploaded data in the OSm dev server.  See edits here: http://master.apis.dev.openstreetmap.org/history#map=14/34.0220/-118.4653\r\n\r\nSome notes:\r\n\r\n- The download data should only show after you click start mapping to avoid mappers working on a task without locking it<br> <img width=\"409\" alt=\"screenshot 2016-02-19 11 57 29\" src=\"https://cloud.githubusercontent.com/assets/126868/13168211/67e822f6-d700-11e5-94ab-59ac8cdd6cb4.png\">\r\n\r\n- Is it better to just have one button to download both OSM data and import data into separate JOSM layers at once? What is the advantage of having two buttons that we click one after the other?\r\n\r\n- We need an **object conflation tool:**\r\n - When merging two objects, the mapper only needs to select which object's properties to inherit. Currently we need to select this for each individual tag and is not practical.<br>\r\n<img width=\"730\" alt=\"screenshot 2016-02-19 12 35 31\" src=\"https://cloud.githubusercontent.com/assets/126868/13168720/4c591dce-d705-11e5-9a71-e4f780b562c9.png\">\r\n * Like **replacing geometry we need a replace tags function to update the tags from another object and delete the unused geometry.** Current workflow is, selecting import geometry, copy tags, select target geometry, paste tags, select import geometry and delete it.\r\n* **Do we join building parts**?  If yes, we should use the attributes of the bigger building, this needs proper joining of attribute tool as explained above.\r\n* **For areas with existing buildings in OSM, we need to properly visualize the difference between the imported data and existing data**.  Suggestion is to **prepare a map paint style  (mapCSS) for JOSM**. \r\n* Should we import the  `building:levels=<4`?\r\n* **If no building exist in the imagery, do we delete**?  The imagery is 2014. The building data is 2008 and 2014.  It is possible that the data is outdated.  Conversely, **should we trace building if its visible in the imagery and missing in the import data?**\r\n* Importing guide needs more explanation on **how to do comparison from existing data and conflation.**\r\n* The TM task boundary was based on census blocks, this makes it difficult to visualize the edges the task a user is working on.  Suggestion is to create a **background image overlay to show the boundaries of the task.**\r\n* Some buildings have an offset from the imagery, should we **move the building polygon?**\r\n"},"comment":{"url":"https://api.github.com/repos/osmlab/labuildings/issues/comments/203853178","html_url":"https://github.com/osmlab/labuildings/issues/43#issuecomment-203853178","issue_url":"https://api.github.com/repos/osmlab/labuildings/issues/43","id":203853178,"user":{"login":"maning","id":353700,"avatar_url":"https://avatars.githubusercontent.com/u/353700?v=3","gravatar_id":"","url":"https://api.github.com/users/maning","html_url":"https://github.com/maning","followers_url":"https://api.github.com/users/maning/followers","following_url":"https://api.github.com/users/maning/following{/other_user}","gists_url":"https://api.github.com/users/maning/gists{/gist_id}","starred_url":"https://api.github.com/users/maning/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/maning/subscriptions","organizations_url":"https://api.github.com/users/maning/orgs","repos_url":"https://api.github.com/users/maning/repos","events_url":"https://api.github.com/users/maning/events{/privacy}","received_events_url":"https://api.github.com/users/maning/received_events","type":"User","site_admin":false},"created_at":"2016-03-31T09:37:45Z","updated_at":"2016-03-31T09:37:45Z","body":"Immediate tasks hit.
