[Talk-us] Phoneix, Arizona open data

Tue Aug 29 22:15:42 UTC 2017

Hi Greg & other Phoenix area mappers —

To explain a bit more. We will mostly be looking at navigation-specific attributes similar to the editing we’re doing in Detroit (see here: https://github.com/TelenavMapping/mapping-projects/issues <https://github.com/TelenavMapping/mapping-projects/issues>) so: turn restrictions, missing roads (if any), one-way roads, traffic signals, some carto features such as parks. As always we will respect local mappers’ work above everything. Sources will be Bing / DG, OpenStreetCam, Mapillary, ImproveOSM (GPS based detections) augmented with government data where possible (which is where Horea’s question came from).

Where possible we will publish MapRoulette / Tasking Manager jobs for anyone to participate. If you have any (other) specific insights to share, like locally specific mapping practices, things on the ground that are different / specific to the area, data you’ve worked with, let us know. Thanks!

Another way you can help is drive around and capture OSC / Mapillary in the area (duplicate coverage welcome) even though OSC coverage is already pretty good (mostly thanks to Greg).

If you have any questions or concerns just email me or bug me on Slack. If you know of any Phoenix area mappers that are not on here / are unlikely to read this I would appreciate it if you could put us in touch with them.

Martijn

We’ve made a research for local data, and we’ve found this open source data:https://www.phoenix.gov/opendata# <https://www.phoenix.gov/opendata>. The specific datasets are: Street center line for City of Phoenix <http://mapping-phoenix.opendata.arcgis.com/datasets/street-centerline>, Street Name Labels <http://mapping-phoenix.opendata.arcgis.com/datasets/street-name-labels>, Traffic Restrictions along Streets <http://mapping-phoenix.opendata.arcgis.com/datasets/traffic-restrictions-along-streets> and Traffic Restrictions at Intersections <http://mapping-phoenix.opendata.arcgis.com/datasets/traffic-restrictions-at-intersections>.

I know that the MapBox data team has already come through and added to lane counts and turn restrictions along major roads.  I believe other mappers have worked hard on OSM turn restrictions too Paul Johnson appears to be prolific with the work.  Please contribute how you can.  Your edits are welcome.

Look at the beautiful Tiger fixup map.  http://product.itoworld.com/map/162?lon=-112.04146&lat=33.56395&zoom=11 <http://product.itoworld.com/map/162?lon=-112.04146&lat=33.56395&zoom=11> I am going back through now removing all the tiger tags and rechecking geometries created with Yahoo. I know Hans has done a great job in many areas with the Tiger fixup.  Dave Hansen, balrog-kun, iandees  I love you guys for work you did that I did not have to do.  Tiger was the best import ever!  balrog-kun's name expansion saved me so many hours of time.   iandees import of geonames saved many many hours of research.  These automated changes allowed me to work on other issues.  I am an osmer that thinks that the Tiger import was a good thing!

I looked at the site along time ago when it was launched  but found these two confusing links.  I cannot tell if they have just relinked the phoenix.gov <http://phoenix.gov/> website terms into the opendata terms. Is it opendata or closed data?  Perhaps you'd want to send a note to them to clear up the questionable terms.  The site appears to be more of a sales pitch than anything with a real substantial opendata contribution.
