Bot idea: Fixing invalid capitalization of primary tags 15 days ago

@BushmanK - I haven't spent much time with Keepright - but I suspect you are probably correct. I thought of Maproulette because I recently fixed a number of buildings with self intersecting ways using Maproulette.

Another alternative might be Maproulette which means the edit gets a human to verify the object.

Introduction 15 days ago

Welcome to OSM. Summerland looks like a nice size town for one person to map. I live in a small town just north of Seattle. I've spent the last three years doing what you are doing, fixing street names, adding businesses, mapping sidewalks, adding parks and water features.

I would caution against using Google Streetview. Their terms of use preclude us from using it to derive data for OSM. Check out OpenStreetCam.]( - While no images of Summerland exist today, all you need is a smart phone, phone mount, and a car or bike to add your city.

Check with your provincial government for hydro maps. I'm not sure if BC offers them or if they are licensed for import into OSM, but they can help you with stream direction and connections.

Beginning the mapping of Phoenixville, PA 22 days ago

You might try OSMTracker for android, not sure if there is an iOS version. The app allows you to take pictures or short audio recordings which can be geolocated to the gps trace.

I just take pictures while walking, trying to keep them in order and making sure to get the address/unit number as well as the business name. Then I just use them for reference to add to OSM.

Good luck, Clifford

Validating Wikidata tags on OpenStreetMap about 1 month ago

wikidata-osm is a nice visual tool but it's not suitable to fixing problems or even marking which problems have been fixed or marking ones as valid/invalid. That would save time by not having people look at a tag that someone else has already investigated. I would suggest using maproulette.

Maproulette could be used to mark the osm wikidata tag as valid - such as Unimak Island in Alaska. According to wikidata-osm the two nodes are both on the island but separated by a few kilometers. Or Sanak Island, also in Alaska. OSM has the node on the correct island while it looks like wikipedia has the node in the ocean.

By using Maproulette, nodes could be either marked valid, invalid or fixed. This way even Wikipedia could improved.

Easy Access to United States NAIP Imagery for JOSM about 1 month ago

The Set WMS Bookmark would have worked but I was having a problem with chrome blocking so I did the work around.

Easy Access to United States NAIP Imagery for JOSM about 1 month ago

Found my problem. My browser was blocking

To add the imagery permanently, I needed to go to the link for Washington 2015 1m select wms and copy the url found start after xlink:href=

My mine must be muddled. Can you give more info on adding to JOSM?

Pokemon Go trash about 2 months ago

@forever2darkness - In the US we need more mappers in rural areas. Mostly we attract people in large cities, many with an active community. Our OSM meetup group has over 700 members. I'm real excited when I find an active mapper in rural Washington State.

One nice thing about mapping in rural America - you don't have fights over how something is mapped. You are the expert. So go fix any bad mapping you did early and go improve your town. Join us on talk-us mailing list or join the our Slack channel.

If you need help finding your old edits just let us know.


Pokemon Go trash about 2 months ago

I send out welcome messages to new users in Washington State. Even ones that added crap. I encourage them to add only what can be verified on the ground. Most of the edits are good faith attempts to add data. I've spent hours verifying parks against local database. It turns out that most are accurate. Maybe they don't match shapefiles from cities or county shapefiles but they do add in parks. I've also seen a surprising number of edits from these Pokemon users. Typical new users do one changeset. I've seen a number with over 10 edits. It turns out that most of the vandalism is easy to spot. Parks polygons over residential neighbors is real common. Trails that couldn't possibly be correct.

Do they have quality problems - yes. But mostly because they are not familiar with OSM. Abbreviated street name, paths/footways not connect to adj. streets, and untagged ways.

The last new person changed a street into a waterway. But interestingly he also correct the street name. Local knowledge is useful. I removed the waterway and removed the bogus footways he added. End result, we have better data.

I'm as frustrated as you with vandalism. But I think potentially we can gain some active contributors if we help them.

I'm well aware of the post on Reddit. See my comments on the OSMUS Slack Channel. I also know that the number of new users has increased significantly. In one day, I contacted as many new users as I used to in a month.

I've scheduled a meetup for our area for next weekend. One of the topics is editing for Pokemon.

Rather than fight Pokemon, we need to welcome them with encouragement to become active community participants.


What's Wrong With Bing Maps? 2 months ago

Have you tried other aerial imagery such as Mapbox? Both are slow to load initially, but fast once the cache is built up.

You should be able to change your location under your account in "My Settings." be sure to save the change after you move your marker.

What can I do? 4 months ago

Rick, Lots to do. Arizona roads need lots of care. When I'm visiting my Dad in Tucson, I spend most of my time getting roads fixed. The problem was the initial TIGER import. The TIGER quality in Arizona was really bad. The good news is - it's easy to fix.

Have some fun. Join us on [Slack.](Sign up at ) Post on Facebook

And just get out and map.

Best, Clifford

Building local mapping communities 4 months ago

Joost, I just added my scripts to github to capture new users using the IRC #osm-bot channel. You can find the scripts as well as my welcome message, which came from your community.


Apartment complex addresses 5 months ago

I applaud you for adding addresses to buildings. Hopefully someday soon, every address will be in OSM.

My solution to apartment numbers is using a node with the address, including the unit number (addr:unit) inside of the building outline. The individual units will render - but only with the housenumber. Tag the building outline with the main address. Check out Parkpoint Condominiums that was done a while back.

Road Segments, naming streets and Town-land boundries 6 months ago

We had a similar discussion last night. Roads connected to landuse. I usually un-glue roads connected to landuse or admin boundaries. It would be great if editors complained when landuse, landcover or boundaries are connected to roads.
