New 'TIGER reviewed' map layer for ITO Map
In response to a comment left on this blog some time back we have created a new 'tiger reviewed' map to show which roads in the USA have been checked since import using TIGER and which have not. It seems that most roads still have their 'tiger:reviewed=no' tagging, even those that have been edited in the past few years. Green is used for roads that have had their tiger=reviewed tag removed; blue is used for roads that have been edited in the past three years but which still have their tag; roads in red and orange still have their 'tiger:reviewed=no' tag and have also not been edited in the past three years. Lighter and thinner lines are used for minor roads.

thanks much (i left that comment). this is something that i believe is much needed and will be very helpful. i'm looking forward to using it to help plan my review activities.
Indeed, I saw your comment and that was the spur to create it. I hope it isn't going to give you too much work to do! I haven't put anything on the US talk list - you may like to do that. Any also make reference to it from the wiki.
Many thanks, this looks very useful.
i already mentioned it on the OSM US Facebook group, will have to send something to talk-us. it's not adding to my work load, i was going to review these roads one way or another, but it's helping make the planning go faster.
This is most helpful. How can I download the data for my county and do some followon processing?
What will the update cycle be on this new Ito Map Layer?
The update cycle is daily - new data arrives at about 17:00 UTC at the moment. You can't download data from this service, but the data is just a copy of OSM from the previous day so use the normal OSM export systems.
This is great. I've linked it from the TIGER Edited Map information on the OSM wiki, but I think we could give it it's own page (or at least a section on the 'ITO Map' page perhaps.
I don't find the 'tiger:reviewed' tag very interesting or useful for the reasons I've outlined here, and so I think the the difference between green and blue on this map is a distraction
...but the orange is very distinct and that's what matters. We have to mixup to the TIGER data to eliminate that orange!
Helpful + utility of reviewed tag: I agree with Harry that this is a great resource, but I do disagree on the utility of the reviewed tag; because so few people remove it, I can typically tell where _I've_ touched things in my regular stomping ground by using that tag as a guide. Might be misguided in this, but it's been helpful to me up to now.
Subscribing to the product: Long ago, I subscribed to the OSM Mapper product and it appears on my ITO homepage. Is there a way to subscribe to this new product so it shows up on the same page?
While you are considering meta-data based views ...: One thing which might be useful is a meta-data based view which keys off of the source tag. For instance, work done with the 'Yahoo' (and related) source tags might be benefited from a re-visit and review in context of Bing imagery. Just a thought ... something that's no doubt come up in your brainstorming sessions.
Suggestion for "Key" link: Consider either rendering the Key link at about 5 times its present size and backing or limning with red ... until the first click on the link for any one logged in individual, then thereafter revert to the current format. Initial finding of the Key link was a "gee, where is it" exercise until I found it, and I'll remember where it is everafter now; but that first huntaround was annoying. (the elusive addedvalue link - a property of many many a UI)
Lots of messages. Trying to cover all of them.
Firstly, I wasn't aware of Mapquest's excellent 'tiger edited' resource when I created mine. I would now be inclined to change my colours to match theirs to make it easier for people when moving to and from, except that red/green is problematic for RG colourblind people (10% men). I would guess that neither map performs that well actually. Is it worth ignoring the reviewed tag as Harry suggests? I think he has a point. Regarding brainstorming, our plan is to open up scripting on maps to the community so people can produce just what they want to produce. More about that early in the new year. At that point it will be possible to 'subscribe' to ITO Map and it will appear on the tool bar. Thanks for the 'key' comment, I agree it is a bit small - possibly it should be open by default for new users.
Thank you very much !
This stylesheet is extremely helpful as I am using it to double-check all of the ways (that were imported by TIGER) in my town.
For myself, the tiger:reviewed key is really useful for numerous reasons. When I first began mapping my town, there were a lot of ways that extended longer than they did in reality (through bing imagery or on the ground, personal visits]. In those instances, I split the ways and then deleted the non-existent parts. However, these ways would show up as 'green' and already edited in Mapquest's TIGER:Reviewed map that was earlier discussed.
In the instances when I modified the ways thanks to bing, the data had improved but it wasn't complete in the way that a personal survey would be (verifying the street name, whether it's one-way or not, or street changes made after the bing imagery). This is why I find the blue/green colors on the map very helpful because some users (I don't mean to vilify them) who aren't local to my area did extensive editing based on aerial imagery, but didn't delete the tiger=reviewed nor add the additional information like .
In the case that they did remove the tiger=reviewed tag, how would I know what areas of town haven't yet been surveyed by local people on the ground ?
Thus, once I personally verify the information on the ground, I remove the tiger=reviewed tag.
Looks like the the map moved to a new location here:
>>> ITO map TIGER reviewed <<<
(Link on the blog post is broken)
Thanks Harry for letting us know, we've now put in the appropriate redirect to the new location, so the links should now work again.
